Recoil on the 308 is not that heavy unless you are recoil sensitive. Since it is uncomfortable to you, I would suggest you replace the recoil pad with one that is designed to soften the recoil better first. For heavy recoil rifles, I really like the kick-eze. It will definately tame most rifles. If that dosnt help enough, then got to the brake. The kick-eze should drop the felt recoil of a 308 to about a 22-250.
No such thing as a stupid question. What is stupid is not asking it.
