Dear all
I own a 1873 in 38 WCF, it was manufactured in 1892. It is good condition, bore in goood shape. I have been researching a lot, since 1892 seems to be a bit earlier to the transition to smokeless powder, so probably this rifle was originally intended to shoot black powder ammo. I really want to know how safe would it be to shoot modern 38-40 cartridges, in my location is pretty much hard to reload or to get cowboy action ammo.
I really thank your professional advise

I have shot different brands of new old stock ammo (Remington, Winchester and Western) in my old 73’s and have had no problems. If the box said something like “High Power” I didn’t buy it. If its from a handloader guy selling stuff then I would be a little concerned.

“there is no problem with shooting the modern Winchester brand ammo” – what about other brands of ammo – is it all safe to shoot in a blackpowder gun?
Thanks
If it is one of the major brand companies, and is not marked “High Velocity”, it should be safe to shoot. That stated, you need to do your homework, and decide for yourself if it is safe to shoot in your gun. Like Bob, I have shot Winchester, Remington, and several others with no issues. With off brands, and specialty makers, I would check with them to determine if it is a safw load for an original Model 1873.

I use Starline brass, a 180 grain bullet I cast from wheel weights and a full case of FFFg black powder or a moderate charge of Unique to make ammo for my 38WCF rifles. Rifles like yours are a good reason to get into loading, maybe even casting.
Probably off topic and out of my lane, but I used to have a SAA in 38-40 (talk about anemic) and people who know more than me (everyone) said to make sure I did not shoot 38-40 rifle rounds in my 38-40 revolver. Never understood that but always told the store I was buying from that I wanted them for a revolver. Maybe you all could educate me. Are they the same size with different loads, or ??? Do they fit both revolvers and rifles? Anyway to tell the difference without a box? If you are worried about an old Winchester 73 could you use the pistol rounds in it? Thanks in advance.
The loads are different when loading for a revolver vs a rifle. Crack open a Lyman’s reloading manual and compare powder grains in the rifle section vs the revolver section. No way to tell once loaded unless if you pull the bullet on one and weigh the grains and know what powder was used. Yes, perfectly safe to shoot pistol rounds in a rifle–provided that they are not so anaemic that they don’t actually travel the full length of the barrel.

The ammunition manufactures came out with a high velocity round developed for the Model 1892 and not intended for use in revolvers or Model 1873’s. It was eventually discontinued as there were instances of people using this round in the wrong guns.
“At one time there was a high velocity factory load offered for the .38-40, intended for use only in rifles. This was loaded with a maximum charge of smokeless powder and had a catalog MV of 1775 fps. This ancient “+P” load was discontinued because shooters insisted in firing it in black powder revolvers and other unsuitable actions with disastrous results.“
