I can only go by my personal experience, have over 1500 rds [handloads] thru my Model 20 and haven't had any problems. Sorry to hear your 10 MM malfunctioned. Take Care

I have a Burris 2-7 on an Encore 17.5 barrel in 300 Win. Mag. barrel. Its been a very good scope, been on that barrel for about 3 yrs and no problems.

I was thinking about having an Encore barrel built in this caliber [18 to 20 in. long] was wondering if anybody else was shooting this caliber. Opinions pro and con appreciated.
