What should I be seeing with a 28" barrel shooting 215 bergers from a 300 Winchester Magnum.

I seem to by getting 2835 using a magneto speed. This seems kinda low to me.

Thanks
 
Sounds right to me. Without knowing your posted number, I would have guessed 2850 tops. I am putting together a 308 Norma Magnum. i'm hoping for 2750-2800 fps from it with the same bullet.
 
I get 3000fps in my 3 groove 28" barrel, 3100fps in my 4 groove 30" barrel. I get the same speed as you in my 4 groove 26" Kimber barrel.

Cheers.

I get right at 3000 fps with mine. I don't have a magneto speed: but drops out to 910 yds are spot on. 26" BRUX and used a PTG TAC reamer with a added 50 thou of free bore. 79 gr of H1000 with FED 215 primers.
