Here's where someone like yourself comes in. Ive have been researching last couple days for two good rounds to send them, a lighter and a heavier one. I have come up with a 200g nosler partition and maybe a 215 or 230 berger hybrid. I am looking for the best long range load for deer and elk a past 1000+ if need be. What rounds and exact loads/OAL would you recommend. If it is easier I would like to call and chat, my number is 757 701 6266,
There are things I need to know first. One, are they using a standard reamer with Weatherby freebore?
I have helped set up a lot of 30-378's for long range. The bullet we are having great accuracy at distance with is the 230 Berger. We have been using the OTM version that has a G1 BC of .719 with H-1000 and a FED 215 M primer. The accuracy has been awesome and velocity is good too. The 230 Makes this large cased 30 a lot more efficient.
If you will be doing the majority of your shooting under 1200 yards I would consider the 230 Berger Target with a G1 BC of .743. But understand the target has a slightly thicker jacket and will not expand quite as well at the longer distances. But will still most likely be more accurate and expand better than most any other over the counter bullet at longer distances.
