Lyman 457193

I have a mold on the way. How's this bullet for hunting in .45-70? Been thinking of shooting this with black powder lately, so any insight on that is appreciated too.

I shoot that boolit in my Marlin 45-70 cowboy and love it.
Is more accurate than I am.
I think that a 300 grain slug should be great for deer size game.

I've used the Lyman 457193 for years in several 45/70 rifles with great results. To be honest though, I've never shot it at higher than about 1,300 fps.

It's a plain base design and when cast soft and not sized to any extent it will also shoot pretty well in most original Trapdoor Springfield rifles unless they have a challenged bore.

I've had good accuracy with it out to over 800 yards on both metal and targets of opportunity using smokeless powder. I've never tried it with black powder, but I think that it carries enough lube that it should work well when used with an SPG type black powder lube.

It's an old design for the Marlin, and of course works well in the Winchester repeater as well.

This is a really useful bullet and is used in all kinds of singleshot and repeater rifle models. I imagine it is a good seller for Lyman.
As far as killing power, you don't need high velocity to bring down large game when using this bullet. Also, many a modern buffalo hunter has killed his game with BP and this bullet.

I'm shooting a Handi rifle, and sticking with Trapdoor level loads. Been working with 300 and 350 grain bullets so far and they're fine, just wanted the traditional weight. Might go back to the 300 grainers after trying, but this looked like a real good general purpose design.

Rich, I've generally found the 405 grain designs (Lee and Lyman) to be very accurate and a good compromise between the 300 and the 500 grain boolits. They hold their accuracy much better out at longer ranges than the lighter boolits and don't recoil as hard as the heavy boolits given the same velocities.

I'm looking forward to trying some. Might have to give 20-1 alloy a try, I've got some bees wax to try out a recipe for lube.

For me and my CVA 45-70 a tight crimp was required to get good groups. Just keep that in mind if shots pattering more than grouping. But, I bet you knew that.

300 gr. 45-70 boolits are quite accurate out to about 200 yards but start to open up beyond that.

Kungfu,

In your single shot 45/70, try seating the boolits out to where they just touch the rifling when you chamber them.

By doing so, you can avoid having to crimp your cases, yet you will still get good consistency at ignition and good accuracy. Cases should last longer too as you're not stressing the brass with a heavy crimp. It will also help center up your round in the chamber if you have an excessively large diameter chamber.

With my single shot 45/70s this has proven to be the most accurate way to go. It will depend on the design of your boolit, but I think most designs will work. The Lyman 475193 of the OP will certainly work well in this regard.

Of course download your powder charge and work your load back up gradually.

Thanks, I'll give it a go.
