300wm 180gr nosler ballistic tip

[planetwaves]

For 300 WM, I use 73 gr of H4831 and WLRM primers with the 180 gr Nosler Ballistic Tips. Tight groups from my Ruger Magnum Hunter Rifle with a 24" barrel. Haven't chronographed it, but no pressure signs. Also got good groups with 72.5 gr, but increasing to 73.5 gr widened the groups. Haven't tried it on game yet.

I shot 75.5 grains or reloader 22 behind the 180 BT for quite some time with 3/4 MOA accuracy. 3250 FPS out of a 26 inch sporter barrel.

Decided i would try to get the groups tighter, i settled on 72 grains or reloader 22 CCI Mag primer W/winchester brass....I now achieve consistent 1/2 MOA accuracy with velocity at 3085 FPS average with an extreme spread of 11 FPS over a 10 shot string (that took a long time to let the barrel cool .) all the while shooting off my bipod and rear bag.


Very happy with my results, with lower pressures to boot gun) I cannot believe how well this rifle shoots now!
