Should I cut my 375 H&H barrel?

hoytcanon said:
I doubt the outside barrel diameter is the contributing factor, but most of my carbine work has been with medium and large bore rifles, 3 or 4 at .308", but the rest @ .338", .358", 9.3mm, .375", .411", .429"... and quite a few at .458" and above.

Thanks hoytcanon.
intend to do a little remodeling of the Zastava M70 .375H&H. I'm debating whether to shorten the barrel or try to make a muzzle brake thread. I want to install a compensator and mount a Blaser kick stop cylinder in the stock. Given that you have experience, which muzzle brake would you recommen? Thanks in advance for your reply

5/8X24 is a pretty standard thread pattern. Brakes and compensators are very different devices. I used a lot of Ross Schuler custom brakes on projects, but to be honest, I don't know if Ross is even still in the brake game. We are not allowed to possess compensators in Canada, so can't help you there. Most guns intended for compensators are set up with shorter barrels, 20" & 22" being common on big game rifles, but 16-18" are not unheard of.

Barrel leng is 23.5 (600mm). I must cut because in begining have a slot for front mechanical sight. I want remove that slot and cut on 22in and make a thread. I have hope for good precision after that

I went with 5/8x24 as well

Seemed to give the best options

Jeeper,do you have a same compensator?

I don't have a comp/brake yet

Currently trying to decide. Will likely get a cheap KAK as a placeholder. Might go with a rearden with plan B outer threads for a blast shield or eventually silencer/suppressor
 
I've alway been a shorter barrel type hunter. My first rifle was a Mauser 98 first thing I did was take it to metal shop in the 8th grade cut it to 20" finish the end of the barrel and put new sight on it.

375 is not really one of my go to cartridges but if I lived in Alaska it would be closer to the top. The one I have I cut to 20" it a good length and I never make it a second though about it length. I much rather have a shorter barrel that a longer one I need to fight in the brush some day.
 
In Europe, the trend is now short barrel. 20 and 18.5 in. are forced. I like shotguns in hunting. They are agile and easier to manage in the bush. But it is known which calibers can be shot from a short barrel.

I wasn't necessarily worried about QD. Nice to have, but I'm not reliant on it even though I still have the irons

And for $6, I didn't bother verifying anything. So I'll check into it

If it didn't work... Oops, I'll need another M70 to put them on

That's the spirit!!!!
 
OP here.

Got some new accessories to try (new mag spring to hopefully get an extra +1 and two cheap KAK compensators to run and see what it looks/shoots like)

Also got a quick pic from my gunsmith. I picked Cobalt cerakote. There was a small imperfection so he's redoing it, but I got to see a mock up of the color.

I'll be redoing the stock on my own, just to keep costs down.

What you think for compensators?
How much a recoil energy go down with this models?
 
To each his own, but I wouldn’t cut mine if you paid me. I feel a bolt action rifle with a 24-26” barrel balances nicely, especially a magnum chambering.
 
Is cutting down the barrel really necessary ? If a rifle was originally built with a 20” barrel, then I totally get it. For for some reason, the sentimental side of me absolutely can’t bring myself to mutilate a fine weapon by cutting down the barrel. I just feel very bad.

I’ve carried .375 Holland & Holland Magnum rifles equipped with 25” barrels through some pretty dense thickets (such as Rift Valley in Kenya, Zambezi Valley in Rhodesia/Zimbabwe, Luangwa Valley in Zambia & Southern Sealous in Tanzania). The Southern Sealous is particularly bad, because some paths are only accessible by cutting through foliage with a machete. I (much like yourself) initially thought that such a long barrel would be unwieldy in the bush (esp. for on-foot safaris). But it quickly proved to be a complete non-factor. And I’m definitely no Hercules.

Of course, by all means… cut your rifle barrel down if it serves you well. But do take my words into consideration. The longer barrel offers slightly higher velocity, better accuracy and recoil mitigation.

No idea, the ones I got are super cheap so I'm not expecting much. I'm hoping to keep the muzzle blast down more than anything

The Winchesters are so front heavy because they use very thick barrels. I hated it, no where near as nice as my Steyr or Ruger mini-mag

Too late, already at the chop shop

We'll see if I'm cool or an idiot once I get it back
 
Bild a photos when you get him back with the compensator
 
No harm with cutting the barrel to 20". Don't flute the barrel though. While at the 'smithy's shop, get the gun balanced to you' that makes a big difference in the perceived weight and handling.

Would you want a Ruger Super Blackhawk in trade for the HUsky?

Be careful of hunting Chewore South, the area has been decimated.....


Curious about this. I hunted Chewore South with D&Y in September and they did tell me it was there last hunt there.

Which outfits shot it out?
