Caliber question for rifle build

I want to build a 20" "heavy type" barrel for Eastern woods use as a deer gun and bench rifle. Should I go with a .308 or 30-06? I want something a little different and do not known anyone with a short barrel 06. Maybe there is a reason for that. I am a little concerned about the muzzle blast. Do you think it would be much greater than the standard ole .308? Thanks for any suggestions.

For a 20 in. barrel, I'd go with the .308. The 30-06s strong suit is heavy bullets, and a 20 in. barrel is too short for effective use of the slow-burning powders necessary for 200 grain happiness. Most long range 30-06 types favor 26+ in barrels. Mines just under 28 in.

.308, IMO.

There is no real advantage to a 30-06 in such a short barrel. Actually, I'd recommend a .308 even if the barrel were a bit longer. The shorter action may be an advantage if that reduction in OAL is meaningful to you. It should also be more rigid and potentially more accurate, at least in theory.

For the non-reloader there is more quality target ammo available for the .308. Also lots of inexpensive target ammo.

I'd only consider the 30-06 if I wanted maximum performance in a non-magnum rifle. The 06 will give you 100-150 ft/sec more velocity depending on barrel length and bullet weight. For the use that you mentioned, a 100 ft/sec won't make a bit of difference.

Both cartridges have a history of accurate performance.

Definitely the 308 in that short of a barrel. If the '06 then use really fast powder.

Go with the .308 and if you get down my way (Goose Creek), you can try some 180 Aluminum tipped ones. They work great out of the 308 Wichita pistol. Just make sure you get a barrel twist (nothing slower than a 10") that will allow you some flexibility with the advent and deveoping high BC movement.

On the short barrelled 06, HK made some for a while in their HK940 series and they had a "K" suffix (HK940K) on their shorter models.

I shoot a 20" remington and get 2650fps from a 168 amax easily , I've taken red deer in scotland at 520m drt with no problems and the amax seems to kill very well at these velocitys. I also agree that there is more and better 308 factory than pretty much any other calibre.

There is a good reason the .308 is as popular world wide as it is......

Ever consider the new 338 Federal? The larger bore will allow you higher velocity with same weight bullets and longer barrel life. May not be up to BR matches but it would be far more effective on any game animal, especially with the new lighter weight 338 cal accubonds.

Just another option to dirty the waters!!
