whitty, I use that load in my Omega except I use Pryodex the 777 pellets were made to be the " equivelent" of Pyrodex pellets.
As for using245 PB with a 150 gr load they make good varmit bullets" and you can call CVA and ask them for deer they will work all right if you use 75 to 90 all though some get by using 100 gr I would suggest that the 295 is a much better deer bullet, a 300gr xtp in a sabot or a conical also would do well.
