27" or 28" barrel on 300 Win Mag?

What should I go with. It will also have a muzzle break. It will have slightly smaller contour as the Remington sendero. So weight will not be an issue.

Just trying to squeeze some velocity out of it. Thanks

That inch will get you 22 fps on average

Go 28"+ the brake... 22 fps is 22 fps.

I have a 28" and a 30", the velocity difference is about 100fps with slow powder, like Retunmbo and RE25, not so much with H1000.
If I was limited to 28" as maximum, then that's what I would choose.

Cheers.

28" for me. I want me to be happy even when others make fun of my choice.

IIWY, I'd go with what MagnumManiac, you can always have it shorten if you changed your mind but not the other way around.

Will this gun still be manageable to carry?

For years I carried a 28" 7-.300 Wea. Only one time did the long barrel bump into some brush. It will still be most manageable.

Ditto on what Wildcater said. My .270 AI has 30" Lilja barrel ...

That rifle looks fabulous! What scope is that?

Thanks! It's Burris Veracity 4-20x50 E1 FFP varmint reticle with Horus Vision ASLI (https://www.horusvision.com/asli.php) atop a bedded 20 MOA EGW rail.

A fast 26" will beat a slow 28" barrel any day of the week. My Sendero 7stw (26") was shooting my pet 140grain ab load to 3400 fps even. My new 27" shilen is at 3340 fps with ammo from the same box. Same accuracy but 60 fps less.
My 24" 7stw fell off the wagon with this load and only did about 3200 fps, but would wake up with rl26 to over 3400 fps with normal pressures.

As others have stated, a 1" longer barrel should give you a 20-30 fps boost, but do not expect it every time.

What happens if he gets a fast 28" barrel!?

hell will freeze over...


We had that happen once with a Ruger #1 ss in 300win... The rifle (my Brother's) was doing nearly 300rum ballistics with 200grain pills. We were using it for long range prairie dog hunting. I believe he only took one edible critter with it before something else caught his eye and the rifle went to rifle heaven though.
