I've shot the 55gr SP dogtown and the MSS VE bullets with the same effect. In my mod 12 vlp(.223) w/1-9 twist I have to keep them below 3200fps. Around 3150 to 3200fps they'll actually leave a vapor trail and a grey swirl mark on the target. Above 3200-3225 they'll simply disapear before hitting a 25 yard target. They're about MOA at 100 and 200 yards for me, so no complaints there. Now I also reloaded them for my brothers mod 10(.223) with a 1-9 twist and I had to keep them below 2900FPS or the same thing happened to them. I have a friend who I loaded some for his Colt AR-15 with a 1-7 match grade barrel and I was able to get about 300FPS before the same type of effects started happening. So maybe the barrel roughness has something to do with it. I do know the there is an RPM limit which is about 3200 FPS for a 1-9 .223 barrel. I think it's around 240,000 to 260,000. I did a search on here awhile back and found simular results to mine.
As far as saving pelts with these bullets forget about it. While they don't have the explosive performance as V-Max or Sierra Varmit bullets they still make big exit holes.
