Hoping the little 77's hold up well enough on deer, know good and well the scirocco's beretzs mentioned would.
gunner, Pat loves Scenars, as you know. But, IIRC he's using heavier, larger caliber bullets, not sure if he's killing stuff with .224's.
I once (only once) shot a WT with a 6mm 90 gr. Scenar at .240 speed. Big mess, swore off those in the Wby. Now, they may do fine in a .243. It's an art, matching bullet construction with velocity.
The 75 gr. SSII is a good bullet. Those can be a bit COAL sensitive like VLD's. I've used Berger protocol for optimal COAL, works with SSII's just like VLD's. Once you have the optimal COAL, you're good to go.
But, a .22-250 isn't going to push a 77 gr, 80 gr. bullet at warp speed. At around 3K fps, I think an 80 gr. A-Max or VLD will perform pretty well, shouldn't blow up at that speed. For sure, the SSII won't.
