300 win mag barrel length for suppressor.

[Encore4me]

Getting my Tikka T3x super lite suppressed and wanted to shorten the barrel. If I reloaded it wouldn’t be as much of a question due to powder choices. My suppressor is a Dead Air Nomad Ti XC. I can’t imagine ever shooting at an animal over 400yds. What would be your suggested barrel length?

Download Gordon’s reloading tool and put in a few different loads and barrel lengths. It will give you an idea on what to expect. Then decide how slow is too slow for you.

20"

My 300WM barrel is 21" and I am using a Dead Air Nomad 30 on that gun. It is still a bit too long for me, but that is mostly due to the Savage action being longer than most. That being said, the longest barrel I will use from here on out is 20".

As short as that suppressor is rated for a 300wm.

This. At the shot distances you mention, as short as possible.

But at least 16", unless you want to get a SBR stamp.

Personally wouldn’t go shorter than 22” for a win mag. You will be eating a load of recoil for nothing. You could find a 6.5 prc barrel And cut it shorter 18 or so but a shorty 300 win mag is gonna be a super hard kicking.308 basically

I did my tikka 270 at 19. Not a true magnum but still a high performance round. I lost 100 fps from 22.5 and total length is now 26 inches with my R2. Its my 'longer range' non-stalking rifle with a swfa 3-9 & shooting 129 lrx at 3050 fps.

If i were you, Id just trade for a 308 and chop to 17. I did this too, and still get 3000 fps with a 130 ttsx.

Recent personal experience:
Rem 700 SPS stainless. Had to cut, crown, and threaded twice. First time was 1/2x28 and used a 5/8x24 thread adapter. I had all kinds of accuracy issues and got them sorted to shooting just under MOA. Still wasn't satisfied and talked to Thunder Beast, and I was told by them that my OD was too small for .30 cal and thread pitch I had chosen plus stacking tolerances of the adapter. They suggested 9/16x24 and to use their muzzle indexing break. I sent the rifle to them and got the service. All my problems went away. At that point the barrel length was 23.5"

With my 180gr Accubond and IMR 4831 handloads and a Thunder Beast Magnus I was getting 2742fps and small groups at 200yds. Small being sub MOA.
The rifle fit in a Cabela's blind, tree stand, and open country elk hunt.

It's not uncommon to be 400yds from a legal elk where I go, so that distance was important to me. I a papered the loads up to 200yds and shot small steel plates out to 600yds. At 400yds I should have been 2074fps and 1720ft lbs.

Side note, I don't recall but, I think I was at the first node in loading. My 26" 6.5 PRC with Berger 156 EOL, has better numbers past 200yds than that WinMag did. When I get that action back from re-barreling, I will be looking to improve my WinMag numbers at 24".

Yes!

I have had 700 clones with McMillan A5 stocks in the 11 to 14 pound range.

Unless:

You only hunt out of a truck or blind.
