[QUOTE="johnnyk, post: 1242359, member: 307"] I have only tried the 190gn SMK once in my .300WinMag and it was a very accurate bullet. I used H1000 w/CCI 250 primers. This was the "first" time she had the 190SMK's and H1000 and I must say I was well pleased. However, I wanted to shoot heavier bullets and only shot one box of the Sierra's. I tried from 79.0 to 80.5 in 1/2gn increments. All four of these loads were .522" or less, with 79.5gn being the .522" group. 79.0gn was the most accurate @ .142" and velocity averaged 3078fps with an ES of 7.83 and a SD of 4.12. 80.5gn was the next most accurate @ .4185", 3160fps, ES 31.07, SD 13.63. I shot these four loads twice through this rifle and results were repeatable. The 190's were seated .010" off the lands with an OAL or 2.9090" (my chamber). Shortly after shooting these I got a muzzle break for my rifle and never looked back at the 190's. I have shot the 208gn A-Max's for quiet some time now and they are equally as fast and accurate. Pretty soon I plan on running some 212gm ELD-X's and see how they do. Good luck and hope some of this can benefit you. JohnnyK. [/QUOTE]
