I have 100 SMK palmas and 200 178 AMAX. I'm debating which to try out first. The gun is a .308 Rem 700p LTR 20" 1/12. The only powder I have right now is IMR 4064 so I'm going to use that since its so hard to find anything right now. 155s will be fast and according to some buck the wind better, but not a lot of info I could find on the palma version. The 178 AMAX are proven in .308 and there is a lot of data to go off of. I eventually want to get out to 1000 and also be able to use the load for deer and hogs. For know I'll prolly be 500 and in until I get more comfortable. Thoughts?
