"Hi was going to load some of the Hornady 50gr SPSX up for my 223 i have a Rem 700 1:12 twist"
I have shot the 50 gr SX before (a brick - 500) out of my M700V w/1-12" twist. They work fine and expansion on varmints was explosive - pun intended! I was using original BLC2 at the time so can't give a current good load for them. However, I settled on the 55 gr SX over 26.5 gr of H335 and shot over 8,000 of them before I had to set the barrel back to pick up some throat. They are very accurate as the rifle would shoot in the .5s" when I first started using them and was still MOA when the throat was shot out. With the barrel set back the rifle once again is shooting in the .5s" (that's 5 consecutive 5 shot groups).
The SXs are very deadly on small varmints and I have connected on rockchucks beyond 500 yards. I like to "line up" ground sqirrels as they sit by their dens. The max with one shot is 3 KIAs with the 4th very gut splattered. On coyotes I seldom get an exit on a heart/lung shot under 250 yards or so and little pelt damage when they do exit.
Even with the new technology in BTs etc. I find the SXs are still my 1st choice, excellent performance and reasonable cost, in all my .223s of 1-12 and 1-14 twist.
