[QUOTE="johnnyk, post: 1041381, member: 307"] I tried the 190gn SMK with H1000 and CCI250's back in Aug2010, in Georgia. It was 94 deg. that day with a heat index of 110 deg. I loaded from 79.0 to 80.5gn and velocity averaged from 3078fps to 3148fps. Largest group (79.5) was .522" and smallest (79.0) was .142". Currently (2014-15) shooting the 208gn AMax and 210gn Bergers. Using 81.0gn of Retumbo w/CCI250's. These two are tit for tat in my rifle. Accuracy is almost identical at just under .4" and veloctiy for the AMax was 3072fps, the Bergers came in at 3073fps. Installed a muzzle break and recoil pad in 2013, as the 190gn's, even in a 12-13lb rifle, were brutal. These two items are priceless when shooting the heavy pills, IMO. Work your way in to these loads, your mileage may vary. JohnnyK. [/QUOTE]
