LR hunting bullet for 300 prc

[wind gypsy]

I also had my rifle chambered with a .050 shorter neck than SAMMI, I think this really helps with velocity

By neck do you mean freebore?

 

[codym]

Yes

 

[762 ULTRAMAGA]

Yes

If you have less free bore than a saami chamber then the bullet will be seated deeper in the case and velocity would actually be reduced.
Did you actually throat it out .050 beyond saami?
Sorry I'm confused the way you are describing it

Nope it doesn’t, do some research. Dave Tooley recommended the reamer and chambered my barrel. Couldn’t be happier and I am getting much better velocity than those with the longer free bore.

 

[codym]

I have a couple friends that have went to this chamber vice sammi spec and have gained velocity.

I would take a serious look at the ABLRs. I think a bonded bullet is a good compromise between an all copper and cup & core type bullet. The Bergers will likely have great accuracy but after seeing their performance on two bulls this year I would try to work up a load with a bonded bullet. I know this is designed for a longer range rig, the Bergers would probably perform fine at distance but if you're presented a closer shot they tend to break up.
