338 edge barrel length

I am looking for input in regards to the proper barrel length and rate twist for a 338 edge using 300 bergers. I have heard anywhere between 26 inches and 30 inches not including muzzlebrake, but that is a broad range. Any input is greatly appreciated.

Re: 338 edge barrel length

1 in 10 twist and I would go with a 28 or 30. It depends on what you really want from the rifle. Will the 30 be a problem for you packing it? Are yu going to shoot past 1500 yards?

The 28" will gve you a muzzle velocity around 2800 fps with a 300 Berger and H-1000 for powder. The 30 will probably get you closer to 2850.

Im thinking on trying 26" on a new barrel i just purchsed from this site it has a 9.3 twist. Guess it will either work or not.

Re: 338 edge barrel length

You can go with 1:9.3 to 1:10 twist. Broz is right give us a little more information on what you plan using this rifle for and we can better help you. You are going to lose 15-25 fps per inch depending on the individual barrel.

I think accuracy will be good, but it will have a little less velocity from the shorter tube and a little loss from the twist too. But I don't think it will be a huge deal. If you are considering a 26" you are most likely wanting a rifle to carry and such and probably not worried about the ELR shots past 1200 yards. So it will probably fill yourneeds just fine.

Re: 338 edge barrel length

I talked to tech support at Berger and they suggested 1-9.5 and 1-10 twist should stabilize their whole 338 bullet line. I think I decided on a 1-9.5 with a 28 inch barrel plus a muzzle brake. I am not sure on the brand of barrel. Any suggestions?
