Just laid in Lyman’s 4th Edition of the Cast Bullet Handbook. Several recipes of interest to me list a powder Lyman abbreviates as “Rx7” that I am inclined to believe means “Reloder 7” — although that seems an oddball way of referring to it.
I’ve seen “RL-7” and “RE-7” but the “X” makes me nervous enough to ask before I start building 45-90 loads with it.
Thanks,
Bill

OOH Bill you just gave me a warm and fuzzy when you said 45-90! Lets hope that stuff works.

Zeb, I have taken the “Rx7” to mean Reloader 7 for years, but admit to not using any recipes from such listings. “Propellant Profiles” only addresses Reloader 7 spelled out. Over time, Reloader 7 was not available as a canister powder for reloading but was brought back, due to popularity. The “Rx 7” may have predated the newer availability. I would approach loads judiciously in any situation. My old Lyman reloading manual shows Rx 7 for a lot of cartridges such as the 32 Special, .30-30, .45-70, etc. Tim

Tim, Alliant (whoever that is, these days) swears by all it holds to be Holy that Reloder 7 is the business for big bore low pressure cartridges like the 45-70 and bros. It is said to be fairly bulky and position insensitive.
TxGunNut has generously gifted me some of the prettiest 330 grain .458 hollowpoint lead bullets you,ve ever seen and I propose to load a series for both 45/70 and 45/90 and see what’s what. I would be pleased to see an accurate load at 1300 to 1400 foot seconds at the muzzle.
The quest for a reasonable supply of Accurate 5744 has gone for nought. I have a can Mike gave me I’m saving for 33 Winchester duty but enough to service my forty-five caliber rifles can’t be had right now. Lyman has a number of recipes for big bores using RL-7 so, when Midway announced it had gotten some in, I threw caution to the wind and bought three pounds. The kegs were gone before I could buy one. I hope it works because it makes an expensive fire ant killer.
Tom, Rock Island Auctions had a big display at today’s TGCA show up in Denton. All the treasures of Ind and Araby laid out for us proles to marvel at. Nothing to buy, just to note down for bidding later.
There was one RIA lot you just have to have to impress your fellow downeasters: a small caliber [45-70] “Police Gatling” for riot control. Yes. Shiny polished brass cover, brass and oak tripod. And an engraved Colt placard dedicating it to somebody. I think it was to be wheeled up on a carriage drawn by deaf or drugged horses. Take up a collection and buy this bad boy for your local cop shop — just to watch the ACLU disappear up its own ….. well, you get the idea.

Thinking of using Reloader 7 for the following
40-82-260
45-90-300
50-110-300
Using lead–what would be a safe starting load? Bill

I’m planning on doing the same with a 45-90-330. I’ve been getting recipes for 45-70-400 but nothing so far for the former.
As soon as I find something and use it without parting my hair with the Winchester’s hammer, I’ll post it.
