Thread: Suppressing a 45/70

Hey team. Possibly looking at a henry single shot in 45/70. Just wondering how short you can cut the barrel on them and what the go is with suppressing them.
Cheers

If you have your eyes set on the henry that is fine. But just to let you know, there is a bergara single shot as well imported in the country that comes with the barrel already threaded. I would try to keep the barrel around the 18" mark,

It's not a binary thing like "17 inches is fine but 16 inches is instantly fucked". As the barrel gets progressively shorter, the intensity of the muzzle blast increases, so the quicker the baffles will get eaten away. You'd probably have to go stupid short to threaten the structural integrity of the suppressor and it'll vary by make - so best fire that question at whoever you go with, if you're gonna do that.

45/70 needs a big suppressor. It's a big exit hole with a lot of gas and so it needs a suppressor with a lot of forward volume to strip as much as possible to make any meaningful difference to noise.

for me...anything less than 18" and you wasting the round...... with longer barrel you WONT need to suppress unless you shooting stupid hot loads and lots of them. I dont even notice mine at 28" my ears dont ring at all...its fun to fire becuase of it.

nah old n grumpy...only partly deaf LOL
but seriously a longer barrel takes blast away from your ears,it is further away so everything is better,angle included..... love shooting the hefalump gum with black powder duplex loads......so much fun indeed.

Am going to suppress my 45/70 Henry at some stage. Gonna talk to Friwi about when I have the funds.

With suppressor on I’d want it to be no longer than it is with original barrel. Will be using factory loads.

Yes high has volume so reasonably big suppressor will be best
But relatively low pressure from a 45-70 so it won't eat the baffles like a high pressure round in a short barrel

I cant see subs being tough on a suppressor.
The quietest sub rifles have vented barrels so instead of cutting the barrel really short and hanging a long suppressor off it, a stronger set up might be venting the barrel from inch 12 on so that the overall set up is shorter. Just an idea, someone here will know if its viable

Can it be done with a muzzle forward on the marlin guide guns?

If you meant Something like that :
Can simply fitted at the end of a non ported barrel

that works with the smaller calibers like the 357 and 44 in the model pictured but my 45/70 1895 sbl dino gun does not have enough barrel protruding past the mag tube to allow fitment of supressor .
It would need what I would imagine would be a fair amount of money spent to shorten the mag tube slightly and cut a new dovetail in the barrel for the mag tube mount .
Obviously a different model may not have that problem , with say the 20" barrel as opposed to my 18.5" .

Yes, DPT make them, looked into it a while back.

Consider a .44mag singlehot as well . . With 300grn. XTP bullets you have a Big hitter & using .44 specials you have subsonic

Hi rossi, I've got a 44 and tried the 300grn XTP. They are very accurate but the lead is too hard ( they are made for protection against Bears) and they perform poorly on game. The 300 grn Nosler HP is much better on game. Neither give performance even close to the photos you posted of what you got with the cast big metplat bullets in your 4570

hey MoaH, good info . . back n the day when i 1st tried the XTP they were a real step up from the cast classic pistol bullets i started with, performance was brutal at close range on Goats & Fallow, smashing running animals in med step, Big holes in their chest you could look into, clockwork spread across the ground . . holy fck moments. After that i got seriously into big bore subs.
but Nothing stays the same, old designs change . .
