I have some data that says 35 grains of 4198.  I’m going to try 31 grains and work up.  I’ll let the chrono tell me when to stop.  I use 31 grains in my 45-90 and get around 1,550 fps.  Same bullet but more case volume in the 45 EX. 
  

Let me (us) know what the ultimate powder charge ends up at.  I suspect that it will be something close to 50 grains.

Loaded the 5 rounds for the 3rd firing with 31 grains of 4198.  This was the most miserable day of this entire process.  Mid 90’s in the garage.  The cases have formed well but this caused me problems. I don’t really have anything to squeeze the necks to get any amount of neck tension.  I tried at least 4 other 45 cal dies but the EX is just too fat near the neck to go into the dies.  I should have stopped and gone into the house to cool off.  One mistake after another.  The worst was I knocked a die set off the shelf.  It hit my scale and the container of powder.   What a mess.  No harm to the scale but after I cleaned up the mess a whole lot of powder got thrown out in the grass.  No way to clean out all the dirt and junk from the powder.

Sounds like it is a good time to pour at least 2-fingers of good whiskey and site down to relax!

I am very curious what the measured velocity will be with just 31-grains of 4198.

I’m done.  Going to read more of Jeff’s book.  No bourbon for me, too early.  I’d just fall asleep in my recliner.  You know me, I chronograph everything.  I put a small wad of toilet paper over the charge to keep it all near the primer.  Nothing like flaming toilet paper in the morning.  I hate cleaning guns, especially when fired with black powder.

I shot the 5 rounds again.  BUT, my chronograph’s rechargeable battery pack died.  I did get data for 2 of the 5 cartridges.  1,136 fps and 1,115 fps.  According to Barnes, Cartridges of the World, 35 grains of 4198 should produce 1,475 fps.  So the 31 grains I used came in under that.  I ordered a new battery pack and should be back in business for next week.  Since I have some brass that has not been fire formed I may use these instead.  This way I know the bullets are real tight in the neck. 

I need to inventory my powder.  After the incident last week I may need to buy some 4198 and probably some others too.  Powder is so expensive.  4198 is around $50.

Chuck,

The factory original Winchester 45 Express cartridge was loaded to 1,633 fps (at 50′ from the muzzle) with a 300-grain bullet.  If you are trying to recreate the factory load specs, you should shoot for (pun intended) 1,650 at the muzzle.

I’m not going to shoot black powder so I will keep the pressure down and stay around 1,500 fps.   If you read Philip Sharpe’s book, Complete Guide to Handloading page 401, he shows breech pressures and with some powders you produce more breech pressure at a lower speed than others.  Unfortunately like most manuals he only goes up to the 45-90.   With 125 grains of FFe the factory load went 1690 fps at the muzzle, according to Barnes. 

While doing research I found in one of the books that toilet paper as a filler was determined to be the best.  I will have to sit down and go through at least a half dozen books to find out which one had the section on fillers.  When I do I’ll post it.

Chuck,

If you intend to use IMR 4198, the peak pressure curve is slower than FFg black powder.  Further, the action and barrel are capable of a LOT more pressure than can be generated by FFg or appropriate loads of 4198.  I have never used a filler of any type when loading BP cartridges with IMR 4198, as it is not position sensitive powder.

In Clyde “Snooky” Williamson’s book, Winchester Lever Legacy, he has a page about using modern powder and reduced loads in black powder cartridges.  This was one of the first loading books I bought in 1988.  He mentions 4198, 4895, 4064, 4350, 4320, and 3031. With 3031 and 4895 being the most consistent.  See page 617.  I use all of these in one caliber or another.  In some cases I developed loads with 3 different powders.  He developed his loads after years of consulting with Elmer Keith, P.O. Ackley and  Lyman’s cast books.  He says that if he doesn’t use a filler between the powder and the bullet, velocities are erratic.  He tried cream of wheat, grits, corn meal, dacron and kapok.  Toilet paper is what he uses.   That’s enough for me.  I have always used toilet paper. 

I’m not going to get into the blown up barrels that were caused when the powder flashed over the top.  Read P.O. Ackley’s book.  It has happened and I’m not going to try to reproduce it.   Keep the powder near the primer.

Snooky’s book gave me the reassurance to use a filler when using position-sensitive powders but as Bert points out some are not. Many of today’s powders don’t have the issues Snooky ran into in his day. Position and temperature sensitivity are reportedly not a factor with 4198. I’d prefer not to use fillers.

Mike you know I value your opinion, but until I see a noted author/shooter put some of the specifics about not needing a filler for specific powders in print, I’m playing it safe.  Snooky was using the same powders including 4198.  The 45 EX is the largest and has the most case volume, next to the 50 EX.  I have experienced erratic speeds when not using a filler or not getting it to hold the powder near the primer in smaller cases.  You have to remember I’m going to end up with about 34 grains in a case that can hold 125 grains.  There is about 2 3/4″ of empty space between the case head and the bullet.  And on the other hand, has anyone seen facts why I shouldn’t?

Let the powder spread out along the case and you can get flash over.  Authors have printed flash over events and guns blowing up.  Just like speed being an indicator of pressure.  With certain powders it is true but with others it isn’t.  Since most loading manuals don’t give you the chamber pressures I play it safe. 

This rifle is 138 years old and not easily replaced.  Let alone my ugly face.

Chuck-

You use a chronograph quite a bit so you have a much better idea about powder sensitivity than I or most other shooters do. I’m fascinated by powder, even Holy Black. The processes and coatings they use to adjust burn rate and reduce sensitivities amaze me, I’m still trying to get my head around these new CFE powders that reduce fouling. I tend to believe what the manufacturer tells us because I suspect they burn through more powder in a week than I will in a lifetime, all in controlled conditions monitored by instruments in more ways than I can imagine. None of that matters as much as your results and that’s what you should base your decisions on. 

My insomnia remedy these days is “Cartridges of the World” and it seems the author and editor thought/think 4198 was/is the best powder for many of the old BP cartridges I enjoy. 4198 is not a new powder but I must admit being a bit more comfortable with the old classics. Fillers are not mentioned but reloading data is not the main focus of the book.

I’ve said this before.  I bought a chronograph in the late 80’s before I started loading.  I have chronographed almost every shot since the beginning.  (not some of the 22 RF’s).  Believe me, Cartridges of the World is always used when I’m trying a new load.  As are about 6 other references.  I use 4198 in at least 5 different black powder cartridges.   When reliable data is available I use 3 different powders to see which one shoots best in my rifle. 

Jeff’s new book is what I read when I have down time.  I am building a F Class rifle in 284 Shehane.  Wildcat 284 Win.  I need to get the stock in the mail to have it CNC’d so I can install the action and trigger guard. My barrel is in Oregon for reaming the chamber.  I am working at changing out my 6.5 CM barrel. I have shot out my second barrel.  This happens about every 2,000 rounds. The barrels are prefit for the action so I can install this one myself.  Then I’ll have to fine tune the powder and bullet seating depth to suit this new barrel. The twist is a little faster, 1:7.7 for the new 153.5 grain bullets.  I will be shooting and loading a 308 bench gun along with the 45 EX each week.  And then there is the wife’s list.

I seldom use my chronographs, I study the targets if I’m trying to evaluate a load. Jeff’s book is more like a textbook, I believe he even refers to it as such. The last few chapters required serious study and I’ve had as many as four Models 75 in my Lazy Susan gun rack on the table in front of my reading chair while I worked my way through. Before JeremyP claimed his prize I had an early, middle and late Target as well as a Sporting Model to examine for reference. The middle is somewhat modified so it’s not much help. The pics in the book are great but I like having one (or four) to fondle or gaze upon. I also have to double back at times when the section I’m reading helps an earlier passage make more sense. I even enjoyed the ‘scope chapter as it helped me understand the optics worn by my Sporting are not “period” as I thought but actually a few years newer. No biggie, they look right at home and I appreciate the benefit of the 1″ tube. Definitely not bedtime reading, I’ve also enjoyed the Army manuals (thanks Elliott!) as they were obviously very well written and illustrated.

Back on topic I sometimes think these big BP cartridges are more trouble than they’re worth unless you’re willing to burn some Holy Black. Those cavernous cases with a little dab of smokeless powder just don’t work like they should, they work best filled with BP.

Mike, I spent a couple more hours going through Jeff’s book.  I wish I had a couple of rifles to compare as I go.  It’s hard for me to grasp everything when there are sooo many model variations.

I sure had less problems shooting BP.  But I hate the mess.  The BP Cartridge Competitors that shoot at the range do use a few grains of Smokeless then the BP.  They have new rifles with great sights or scopes.  They pour their own bullets. Most bullets are 500 gr to 600 gr.   Maybe they would pour some for the EX?  I only have 300 gr and 405gr and they are not target quality.   Since I don’t shoot the 45-70’s that much I haven’t used any 500 or 550’s.

I loaded 5 new cases for fire forming.  Used 31 grains of 4198.  This time I placed a felt wad over the powder then TP from there to the bottom of the bullet.  Nothing is really compressed.  I did push the felt in so if there is any compression it would be here.

I shot some more rounds with different powders and fillers.

The first ones I shot with 4198 and a small amount of TP gave me results that were erratic.

444 fps, 649 fps, 1,136 fps, 830, fps and 1,115 fps.  I was fighting several other things too.  My chronograph battery is giving me problems and none of these had much, if any, neck tension.  I need a better way to keep the powder near the primer so it all goes off at once.   And neck tension would be nice.  I need to call Lee Precision and see if they have a crimp die that will work with the large diameter just below the neck.  It needs to be shorter or larger in the body area.  This was the 3rd firing for these. 

Yesterday the ones I shot with the 31 grains of 4198 were erratic but better as far as the fps.  These had not been fired before so there was a lot of neck tension.   

1,244 fps, the next one only the primer ignited, 1,228 fps.  The 2 that fired did not fire form the case as uniformly as the black powder did.  So I did not shoot the last 2.  These had a felt wad over the powder then TP to the bullet.  I do remember that one of the felt wads was not flat over the powder charge and was at a slant.  This may have been the one that did not ignite?  I do my best to keep the cartridges with the bullets up.  I ordered a box that will hold this length cartridges and allow the cases to be put in, bullet up.  

I pulled the bullets on the 2 and dumped out the 4198.  I will load these with black powder and shoot all 5 again. 

As a side note.  The RCBS impact hammer device for pulling bullets does not work well with this length cartridge.  The final hit each time caused the entire case to fly out of the hammer and over my shoulder.  Luckily the TP kept the powder in the case.  You need a spacer so you have more room in the device so the bullet can come out unobstructed.

Chuck,

You really need to use a larger charge of 4198. Due to the slower burn rate (as compared to BP), the 31 grain load you chose is not creating a sufficient pressure curve.  Dupont specifically published a formula for using IMR 4198 was a BP substitute. The recommend starting load is 40% of the BP load… 125 x .40 = 50 grains.  This is the load you should be using, and I am willing to bet the “erratic” issues will greatly abate.
