Barrel Length and Crown Suggestion

[matthausarchery]

Going to have the barrel cut down on my kimber montana 308. As it stands it has a 1:10 twist and a 22” barrel.
I am trying to decide if I want it cut down to 18” or 20”. I have a 2-7 mounted on it and it wont be used past 300. Will I neuter the 308 too much going to 18”?

I also know nothing about crown options but want something that is slightly protected from abuse in the field.

Thanks for any opinions.

I shoot a tikka in 308 with 20 inch barrel ,love the rifle .

What’s to be gained by a shorter barrel ? a couple oz. ? less FPS ? more noise ? faster handling ?
If the crown is damaged have it recut to a floorboard crown.

I mainly want to have it cut for quick handling and compactness. A shorter OAL will be beneficial in the woods here in the northeast.
Everything I have looked at suggests that I will loose anywhere from 50-100fps, which is not a big deal to me. Noise, i believe can be mitigated with powder selection.
My main concerns would be the ability to stabilize a 180 partition if I went to 18” rather than 20”.

Shorter barrel= more recoil, less accuracy, less bullet speed. Yes shorter is lighter, and faster

Shorter barrels actually generally improve accuracy. A shorter barrel is stiffer and has less flex.

barrel length does not have an impact on what bullets you can stabilize.

louder? Maybe.....you should be wearing hearing protection anyways.

crown type.....doesn’t matter as long as it cut square and clean.

I might just know a touch about short barrels....this happens to be a 6.5-284

An 18” 308 will do you just fine

I also thought a short barrel would cause more muzzle jump and if extremely light gun would make it jump and flex more.

I lighter gun will recoil more. That’s physics.

a shorter barrel will flex less...also physics.

50-100 fps within 300 yards shouldn't be too noticable, if at all.
Any crown as long as it's square.
I prefer a recessed 11° crown, but that's just me.

go 19"
Rem model 7 308 with 18.5 is a killer

Look at Hammer bullets new Absolute Hammer. You will get the velocity back. mtmuley

That makes sense

Split the difference and be a trend setter. Go 19".

 

[noharleyyet]

I'm in the recrown only & Hammer load crowd.

 

[VOLhunter]

16" with 11° target crown. I carry a LaRue OBR with 14.5" barrel shooting 175gr Sierra matchkings way past 300yds. That's my "long gun" as a LEO

Are you going to put a can on it? If so, 18" If not, 20"

Nope.

lol

I will eventually cut it to 20”.
The gunsmith I like is booked for 13 weeks so I will drop it off to him this winter for that and cerakoting.
