45-70
« on: July 19, 2003, 01:10:16 PM »
Please inform me-I have Marlin 1895 rifle in 45-70.I use jacketed bullets 300gr and 405gr-and I use Accurrate 2015 powder as well as 2230--strong/hot loads.Rifle shoots well,what I do not like is that a lot of not burned powder is inside the chamber and barrel.Which powder is good to use to avoid not burned powder? I also use 500gr hard cast bullets and shoot it for fun at  about 1000fps and I use Accurate 5744 powder for it-it shoots accurately,but again and even more unburned powder is inside the barrel and chamber-sometimes it makes a problem to load a new round into the chamber with a lot of powder in it.What powder would burn completely and could be used without any filler to push 500gr bullet at 1000fps?
Thanks a lot for your help.
Best regards,Petr.

Don't know about the heavy bullets, but with the 300 gr's I use IMR 4198.  Get complete burn of the powder and great accuracy.

I use Accurate 2200 both in my 45-70, and 444 Marlin, and get complete burn of powder.
bullet maker :D
I like to make bullets, handload, shooting of all types, hunting, fishing, taking pictures, reading, grandchildren, 4 wheeling, eating out often.

KN, would you give us more info on H-322 in the .45-70?

I'm sitting on eight pounds of it that I bought for peanuts. Some advice and decent data for use with a  405 grain cast bullet would be much appreciated.

I'm nearing the end of my surplus 5744 that has been my .45-70 mainstay. Back in the pre HAZMAT glory days, I bought 32 pounds of it for about what a single pound now costs retail. I foolishly sold half of it covering my total cost and making a small profit before I found out what a great cast bullet powder it is.

I'm shooting a 405 remington JSP in mine, not a cast so I really don't know what to tell you. I got my loads fron the Hornady book, loading a little under max with a mag primer. Be sure your using the marlin data and not the #1 data.

Never fear, KN.

I'm shooting a synthetic stocked NEF that probably weighs under seven pounds. The action will take a lot more than my shoulder will so I load them light.

I've been shooting the .45-70 Marlin 1895 for over 25 years.
When I first got it, I was advised to use IMR3031 for heavy loads. I did so and accuracy was remarkable.
I never considered anything else. But I learned a few things along the way.
First, with heavy loads in which a lot of powder is used it helps to use Magnum Rifle primers. Not mandatory, mind you, but helpful.
But the most important factor when heavy loads are used is bullet crimp. Without a heavy crimp, the bullet starts forward before the powder is properly ignited.
I learned long ago that if I found a great deal of IMR3031 powder in my bore, just as you did, the bullet crimp was the number one suspect. And each time, a heavy crimp combined with a Magnum primer cured it.
I suggest you examine these two factors.
