LL, As I recall, there are 3 sizes for Limbsaver small, medium and Large. The small one fits my 444 and 336's perfect and the Medium fits the 7600 and all my bolts both Rem and Ruger.
The last time I saw one was at Acadamy Sporting Goods and they were under $20.00. No installation fee! A bargain. They really do work
I shoot around 60 rounds (max or near max loads) out of my 444 at a sitting on range day. I don't think the 7600 (30-06) kicks as hard as The Big Dog pushing 300grain lead. My shoulder doesn't even ache. I mean nothing the next day.
