Reloading for Rem 700. 300 win mag/w 220 matchking
Ok, so im going work up a load for my 300 win mag with the 220gr matchkings with AA 3100 powder . I have a 26in barrel with 1-10 twist , what kind of velocities should I expect ??? If anyone can help that'll be great !
Re: Reloading for Rem 700. 300 win mag/w 220 matchking
I use 210 grain Berger bullets and i get 2850 fps using reloader 22 powder with 26 inch barrel/300 WM I have not used matchkings.the BC for berger BTHP bullets is 0.626. i have used them to hit a target at one mile.

Thanks bud ! Seems like you have a really good load . Im currently using federal 215 primer/190gr matchkings with 75.0gr of AA3100. I haven't shot it through a chronograph yet , but im assuming around 3000 fps or more . I'm going heavy just to shot a longer ranges. What type of primers are you using???
Re: Reloading for Rem 700. 300 win mag/w 220 matchking
I use 70 grains of AA3100 (now XMR3100) with a 240 SMK and get velocities from 2750 in a 26" barrel to 2900 in a 28" barrel. I'd say you would get around 2800 to 2850 depending on your particular barrel.
