Have been working up loads for a post 64 Mod 70 Win. and just had to share the latest target.
This rifle shoots groups with 300 gr. Sierra BT, Swift A-Frame and Nosler partions that are all centered within 3/4" of rifle zero (1" high @ 100 yds).
All group MOA if shooter does his part.
The following target was shot with 300 gr Noslers. Shot @ left was a different (270 gr. load). The highest shot was .2 gr lighter than the three shot group 1" high @ 12 o'clock and the shot dead center was .2 gr. heavier. The 3 shot group measured .240" as best as I could measure it!
Funny thing about this rifle, the lighter the load, the higher the 100 yd. impact; as load increases, POI drops. As the maximum load is approached, group tightens up no matter what bullet is used.
Aren't accurate rifles fun?
