[QUOTE="Bart B, post: 562734, member: 5302"] Hope your 7mm barrel's not like a 30 caliber one a friend had some years ago. He had it fitted and chambered for .30-.338 then started working up loads. At several grains over published max, he decided to have the bore/groove dimensions checked. They were .303" and .311" instead of the normal .300" and .308". He called Douglas Barrels and asked why his 30 caliber barrel had way oversize bore and groove diameters. Douglas said they probably mismarked a rifled blank made for 7.65 Argentine Mauser or .303 British as a 30 caliber one. If your barrel belonged to me, I'd check its bore and groove diameters.
