[QUOTE="stcummingsjr, post: 852659, member: 7597"] Well I finally got a chance to run the 130 CE bullets and a few of the 160 gr. matrix VLD through my STW As hard as I tried, My STW would not stabilize the G05 130 grain cutting-edge bullets... My 1-9 twist here at sea level Struggled... I believe I was right on the ragged edge of stabilization ... If I ran the velocity up to Max in this rifle they would stabilize to some degree.. Two would touch, then I would get some slight keyholing and groups would open... Very little consistency.. Some would , some would not be stable.. When I backed the velocity down to just under 3500 fps (My max load where I could still get three firings ) the groups were plagued with Oblong holes. I tried reloaded 33, reloader 25, retumbo , and wc-872 My best velocity came from Retumbo with Rl-25 being a close second. I did put down a few 160 grn matrix vld today!! Ran them up to 3200 fps.. With a heavy dose of wc-872. 160's running at 3200 fps here at sea level appear to need a-little more twist.. I'm going to put a few more down range before I give up on them.. Next barrel will have a 1-8.5 twist or better!!!!!! #%^*dam! [/QUOTE]
