[QUOTE="308 nate, post: 61323, member: 1920"] Winmagman, I built on the standard .223 single shot SA receiver.But a 3" cartridge length will fit in the SA magazine.(Mine is strictly a bench gun.) I also eliminated the barrel nut. This is my feelings on neck length. The 7mmwsm neck measures .247. The 300 win mag neck measures .264. The 6.5-284 neck measures .268. The 300 win and the 6.5-284 are both proven 1,000 yd. cartridges. If .020 neck length is the secret I'll eat my hat.In fact the 6mmbr wildcats are taking neck length for more powder capacity and making a heck of a thousand yard cartridge out of it.I have been very impressed by the 7mmwsm cartridge! I am not competition bench rest shooter but love to shoot and maybe someday when my kids are grown, I will start shooting competition.But untill then I'll just stick with building acurate long range rifles. 308nate [/QUOTE]
