Hi everone Iam gona get a 338 edge build started in a few months and i was wondering if i should get a 30 inch barrel or 32 inch with muzzel break on the end it would be 32 inches or 34 inches total lenght. Maybe if awyone has one they could tell me what velocieties there getting out of there barrels, Iam trying to get some ideas before i send my action a kevin to start this build for me. I really wanted, one really big boomer but after talking to a few people ive decided to go this route ,iam realisticly just shooting to 1000 or 1200 yards so mabey the edge will work great to that distance. Any experience you have with this calliber that you can share with me would be great THANKS TIMMY.

You made the right choice. Go with a 30" barrel plus the brake at the longest. No reason to go longer.

I went with a 29" plus brake, running 300's at 2830.

Biggest reason, much longer wouldn't fit in my soft case.

I would go 28 to 30" + brake what bullet are you planing on shooting and will your rifle be a Single shot or repeater.

Maybe someone that is smarter will correct me. I think as long as powder is still burning and expanding in the barrel you will gain velocity with longer length. A 308 that shoots 40 grains of fast burning 3031 (just a guess) would probablly loose velocity with a 32" barrel because the powder would be done burning and friction would slow it down. You will be shooting over 90 grains of slow burning powder like 7828 H1000 and retumbo. That is slow powder and a lot of it. I think 2 more inches will give you a lot more velocity. I would guess 100fps if not more. Someone correct me if I'm wrong, thats just my thoughts.

Iam gonna shoot the 300 smk or 300 grain bergers thats really the only to iam planning on shooting , and oh yes it will be a repeater.

Im using a 30in. I get 2795fps ( 300SMK) with a load that is shooting in the mid- high .2s. I have shot loads at 2890fps, but my best load has ES of 8fps, and the accuracy is great. Its been shooting 4.6in to 5.5in 3 shot groups at 1000yrds no BS. It makes me look good, and is fun to shoot. I dont think you will gain 100fps with 2in more barrel. I would think more like 40-60fps. Thats about what you will usually see.
