Nice work. My increase in velocity was well over 170 with my 6mm creedmoor. It happened fairly quickly too. Less then 75 rounds.Hi, from New Zealand! I was shooting a fairly new custom 65-284 last weekend and got a 2 1/2 three shot group at 543 metres. 50 odd rounds down the tube.
I shoot off a bipod and bag but this time it was a jacket for the rear rest.
My 18 year old son shot a group just under 3” 20 minutes later at the same distance using my rifle.
Load is 130 VLDH 51.5gr ADI 2209 which is the H4350. @ 3025 FPS. Waiting for the barrel to shift gears as cut rifle barrels usually do and see another 100 FPS or thereabout.
Rem 700 short action,
krieger 26” 1-8
Calvin elite trigger
McMillan HTG -
Swrovski X5i 5-25x56
By the way the rifle and I are handicapped, lefty
It will be great to hear/see what you good folk consider a good group that will be inside the (kill zone) in field conditions at 600,800 and 1000 yards from a long range hunting rig.
