Re: 300 Win Mag Loads- Browning BAR

Like most BAR's the

IMR 4350 is the correct burn rate for the BAR's in most of cal offerings.

In my 1974 BAR in 300 Win Mag I use

IMR 4350 @ 72.0 and 180 gr AB or Nosler Protected Point with WW Brass and WLRM.

I use Hornady reloading dies so far I have not had to use RCBS Small base sizer die. If you expercience ejecting problems or bolt closing u might need small base sizer die.

Next i repaced my recoil spring with a Wolff power spring which helped with ejecting.

And cleaning the piston i use a 20 ga brush and bore solvent at least once a year.

Any Questions feel free to shoot me a PM
