QL request for 6.5 PRC

[Thebear_78]

I was hoping someone could do a quick load search for 140gr Berger hybrid target and re 25, re26, and retumbo.

Thanks

Hopefully someone can chime in with what you need, but if you can’t find it, A few months ago I needed Berger data for my PRC for the 156 grain and sent an email to Berger, just a few hours later Corey called and gave me all the data they had for the 156 grain, and what they felt was best. Real friendly and willing to answer any questions.

I've had the same luck with Berger and data for my 26, quick and friendly. Barnes on the other hand took 2 emails and a week for them to respond that they have no data for that cartridge and pointed me to the hodgdon website. Funny how they have 6.5-300 Wby data, I guess that's what happens when you sign a deal with Weatherby for your bullet to be in their loaded ammo.

No. I have ordered the latest update, but it takes quite a while to clear the border, so it may be in the newest update. However, I'll be waiting for a while longer to see if that is the case.

OK. Thanks
