I'm sure you will find the rifle will shoot what it shot before
just because it shot with one type of 150gr projectile does not mean it will shoot all 150 grainers

Forgive me, but don't I need to use a minimum of 150 grain for hunting larger deer in state forests?

In 308 accuracy is best at around 30 thousands off the lands.
165 hit around 45 from factory 150 believe it or not can be 100 or more.
This jump kills accuracy.
I have bullet pulled factory 150 and re seated them to 30 thou. Group 1/2”.

SCJ429 wrote:It is optimal to jam a bullet but there are reasons not to do this such as, the round will not fit in the magizene, you cannot reach the lands or you don't have enough of the bullet supported by the neck. I would not jam a hunting bullet because it may stay stuck in the lands when you eject an unfired round.
If you are going up to 165 why not 180 or 200?
SCJ429 wrote:To get a Browning to shoot one inch groups is quite an achievement. If the 130 work then I would continue to use them.
If you want to try a heavier pill, by all means give them a try. The better Sectional Density will definitely be helpful in a hunting situation. If I was trying a 180 I would do a ladder test with 2208 until I could not fit anymore powder into the case (without heavily compressing the powder). You will find a load very close to the max powder load. Worry about the Coal after you have the powder charge sorted.

Will definitely be the next ammo I try thru the rifle.
