Hello dakota elk slayer,
I have not shot any 250 gr. yet. I have used Varget with the speer 270 gr. bullet, my load is:
Norma brass trimed to 2.436, fed. 215 primer, 59.5 grs. of Varget (Hodgdon Max.), O.A.L. is
3.280. Velosity is 2429,2411,2413,2415,2402,2410.
Using Siellor & Bellot brass velosity was 2398,2292,2333,2408, 2376
I don't like the S & B brass.
Re-formed 30-06 brass which is 19 to 24 grs. heavier had velosity closer to norma brass.
BLC-2 max. load of 66.0 grs. has velosity 2503,2513,2486,2507,2476
I like this powder with 270 gr. & 286 gr. bullets, Varget was a little more accurate.
H-4350 67.0 grs. with 286 gr. bullet average velosity was 2345
BLC-2 62.5 grs. same velosity 2345 fps.
I have cz 550 fs, didn't expect great accuracy, I noticed my groups were shooting in 2 different
areas. I noticed that the bluing being rubbed off at metal cap. Long story short I steel bedded
the end of stock from mussel back apx. 2 1/2 ", the gun shoots 5 rds. in apx. 1 1/2 " at 100
yards off bench allowing barrel to cool between shots. I"m very happy.
I would like to experiment with seating the bullet out further, using more powder, the CZ 550
has the room, Hope this information helps you.
