Trued BC's for .308 199 Hammer Hunter and .264 131 Hammer Hunter?

[Huntnful]

Anyone have trued BC's for these bullets? Out to say 1000 yards, or 800 yards at least for the 131? Thank you.

My brother is running the 199 HH in an xbolt long range 300 wm, 1:8 twist, seated to 3.602" OAL, MV 3100, BC trued up at .298 G7 with drops to 600 so far. We plan to shoot some more in the next month and will let you know further trued BC as he stretches it our more.

Mine was dead on out to 700. At thousand had to drop down to around .260 i think. Can't remember right now.

I should be running them around 3300 fps and have been doing all my data estimation based of a .26 G7 because of my previous experiences with hammers. That's good to know!

 

[Huntnful]

Well the 131's definitely shoot. 3050fps with 58gr. N560 in my 20" 6.5 PRC

The 131's ended up with a trued BC of .22 G7 at 600 yards.

Is your prc built on a short action? Are you using AICS mags or a mag box with bdl? Reason I ask is the 131 is fairly long and when loaded to mag length in an AICS mag they started around .070 off the lands in a friends rifle I loaded for. I'm having one built currently with a 20 inch barrel so it's good to see what velocity you are getting. This bullet is high on my list to try.

 

[Huntnful]

I'm using a short action and have it loaded to 2.97" just so it'll fit in the mag, which about .070 from the lands when I checked them.

This is also a 20" barrel, and 3100fps would be pretty easily achievable. I'm just staying on the low end because it'll warm up by about 50 degrees here in the next couple months

Sounds like you got the same results as me and they shot great at mag length. I'm going to give them a go in my set up. Thanks for the info
