Re: Highest 30 Cal BC?

Thanks guys. Even though I know it is true sometimes you just want to hear it again. I'm trying to decide which specialty handgun to use for the International Tactical Rifleman's Championship. My 7.82 Patriot XP-100 MV is 2785 with a 180 gr. SGK (15.75 inch barrel). The other XP in the running is a 1-8 twist 6.5-284 which has a 17 inch barrel. This barrel hasn't been broke-in yet, but I am fairly convinced that I can push a higher BC bullet faster in the 6.5 than I can in my thirty cal. This competition is about making hits, not performance on an animal, so it all comes down to what is going to beat the conditions the best. I will be looking for good loads for the 6.5-284 in the near future. Your input would be appreciated.
My distances will vary from 300-1,000 yards on different sized steel targets shooting from primarily the prone position. So any ideas on a good portable field rest for a center-grip XP-100 (H-S Stock) would be recieved with gratitude.

Lynn,
Thanks for the update. From everything I have heard it would be a waste of time to try them (I don't have that much shooting time). Thanks for the offer anyway.

Re: Highest 30 Cal BC?

Well, I was the lucky recipient of Lynns generousity. He is right, the finish on the Lost River bullets is quite rough.

I like to play around different loads.

Here is what I am thinking. R22 is a pretty good powder for the 300WM. I am thinking of loading up 4rd/charge and increase the load .4 grns. Say 70.8, 71.2, 71.6, 72gr and I will post the results here.

The Rifle is GAP 300WM w Rock 1:10 26" barrel. very capable of .5MOA.

Any comments or suggestions?


Lynn, I will send out the Bergers to you today.

Re: Highest 30 Cal BC?

Guys,
With the higher BC of the Berger and JLK, do you MOLY coat the bulets also? If speed is what we want, does it help? Can you push a 210 in a minumn trist barrel faster and get better resistance to wind drift? Any thoughts will be welcome.
