I’ve got an AI ( pretty much a twin of the Weatherby) with a 24” barrel....getting 3130 fps ( according to my chrono) with 250 TTSX’s. Went to 3160, but the groups were starting to open....figured that 3130 was “OK”! Haven’t determined brass life yet....but expecting (hoping) 10 or more firings before discarding. Only “kissing” the shoulder when resizing!

I can’t say that it kills any faster than my H&H, but it does flatten trajectory a bit....making long shots a little more doable! memtb
