I am thinking of building a silenced 45-70
has any one had experience with that combination
I am worried about using lead projectiles
but I want to use 520 grain projectiles and lead is the only option
hows lead go in a silence and whats the best baffle style for a big slow chunk of lead
thanks

You'll need a can that you can totaly take apart to clean the lead out of it. I would think a M or K baffle would work just fine, You'll need some Volume. I'd try loading with some faster burning powder would help.

Sounds interesting
What is the base rifle?

The ability to clean it is important if you are shooting lead bullets but I doubt a 45-70 can would see the amount of use a 22 can does so I am not sure it is absolutely necessary.

I don't know much about the 45-70 but the two things that I have noticed that really dictate what type baffle to use are the pressure and the bore hole size. Something like a K tends to work well with higher pressures and and a small bore hole. simpler designs that do not "work" the gas a hard like a cone tend to work will with lower pressure cartridges but AAC has used cones in their rifle cans (high pressure) with very good results too.

If I were building this gun I think I would use a long cone with a notch cut in the side since the cone works well in high pressure and with a large bore hole.

I'm thinking about getting a new .45-70 barrel for a single shot NEF I have (it's currently in .500 S&W mag) and silencing it, but the issue of sights is what has held me back. I may just have to go with a scope and forget irons, but in either case, I was planning the following:

2" OD, 16" long over a 16" barrel (total length around 24") stainless tube 0.085 walls, aluminum monolithic core with a gap of .015" around the core vs. the ID, guides on either end of the core to center with the endcaps in place, and completely removable for cleaning.

I figured the total cost including the gun, NFA stamp, scope mount, scope, and materials at less than $800.

If you're thinking about an NEF I'd act quickly. Marlin owns NEF and Remington just bought Marlin and Remington has already stated that they are going to reorganize/down size their assests: In other words they are going to shut down NEF. Here's a link to the news release: http://www.marlinfirearms.com/news/press.aspx#plan

I'd go with a T/C Contender or Encore in .45-70 if I were you.

This integration will be seamless and will not affect our customers or our product offerings.

In that very press release it states that they're simply moving the production. I called them a few weeks ago when it was released - they stated plainly that production WAS NOT ceasing, nor was the barrel program being stopped.

As for the Encore barrel, there's no reason to spend that much more money. I can get a complete NEF for less than the price of one barrel.

Stick to the .500! handloads.org lists a 700gr 975fps load for the .500 S&W that would (IMO) be the tits out of a single-shot suppressed rifle. People have loaded the 700gr to supersonic levels so you could even eek it to the 1,050fps region. That would destroy just about any animal on this continent.

Why I didn't think of that is far, far beyond me... I've been loading 500gr bullets at about 1,000 FPS anyway.

I am thinking of using a big martini action with a 12" barrel and an integral silencer to make it up to 18" or 20" barrel length.

That would be quite a sharp looking rifle, and probably just about perfect for hunting to boot.

Would jacketed .45-70 make a pressure difference?

I shoot lead in 458 socom, 510 whisper, 300 whisper, 338 whisper and 9mm. The rifle cans are easy to clean. The 9mm sees more lead through it and it really builds up. I have to scrape it off then use a scrub pad to finish, a real pain in the butt. Jacketed 338, 45 and 50 cal bullets are expensive, so I cast my own 300, 500 and 950 grain bullets for use in the bigger guns.
