My 20-in lightweight would get 2470 with a Max charge of CFE 223, my 24-in would get almost 2,700 if I remember correctly.
By 24 inch 527 would get very close to 2700 with 8208.
All with 123 grain amax or eldms.
I shot two axis deer in the 100 lb range, three or four goats, and a couple of sheep. Never had a penetration issue with 2, 123 Amax going butt to chest on one axis deer.
I was less than impressed with the expansion and shocked delivered by the 20" prompting me to double tap, and in one case triple tap, what I was shooting at.
Never shot anything with the 24 in semi, but both I and the guy who now owns the 527 now, have shot a number of animals with it, and have not experienced that issue.
