Trued Rem 700 in .260 AI with 29" 1:8 twist Gailard barrel
Lapua .243 brass once fired not touched other than uniformed primer pockets
CCI BR2 primers
COL is 2.875"
#s 1-4 are H4831sc (47.5-49gr) with 130gr Berger hunting VLD
#s 4-8 are H4831sc (47-48.5gr) with 140gr Berger hunting VLD
Weather was -13 deg C mainly calm @ 3400ft ASL.
I know this post is REALLY old...but ivo, if your still around, are you getting any pressure signs with your upper loads you showed on that target? What do you think of those loads? 3100 w/a 140 in a 260 AI seems like way more than what most people are getting...I'm having a Krieger barrel made, medium palma contour 4 groove 1in8 twist, and can have it as long as 30" that I'm going to build into a 260 AI on a Remington action, I was figuring on 2,950 fps w/140, if I could get over 3,000 I would be WAY happy, I don't wanna know what I would do if I got 3,100 without pressure signs and decent brass life ha ha...
Also, I'm planning on using H4831sc as well...thanks in advance for any reply.
