You got it made.
We rock the BRNO 602 (prone/bipod) out to 500+yd., with 80'ish grains of IMR 4350 under the Horn. 270gr. S.P.. (work up in your gun)
So many smiles, from so many <new to medium bore> gunners over the past 20 years.
The gongs?, they take a serious beating.
First reloads that I'm going to try will be using H-414 (74.0 - 80.0 gr.) and Hornady 270 grain bullets. Got them loaded already but will keep IMR 4350 available if the 414 doesn't work.
Ordered a Kick-Eze from Brownells this morning, shipped 2 hrs later.
Weighed the rifle, scope, and magazine with 3 rounds today...............only 8.6 lbs No wonder it thumped my poor old bones!
