[QUOTE="Alaska2006, post: 1267895, member: 92741"] Went to the range and ran the Bertram Brass through the 7 STW. Think I need to back the load down a bit. Flat and I mean flat primers. running 80.0 gr Reloader 25 Nosler AB 140 gr and pushing these across the lab radar at 3,318 - 3,331. I Have ran Nosler brass with the same 80.0 gr and didn't notice the flat primers but these were not breaking about 3,300 MV either. These loads today are likely the best ES (13) & SD (4.2) out of 6 rounds I've ever seen out of this rifle. ran another 10 rounds through it and got an ES 47 SD 15.7 same load but barrel was a bit warmer. This load was the std. tack drive for this rifle; 10 rounds is 1 ragged hole <.7 with 2 out layers maybe 1/4" left of the ragged hole. I'll de-prime, measure and size these and come back with some more info. This far I like the Bertram brass. Happy New Year gun) gun) [/QUOTE]
