Waow! That is great mate! I got a similar group last weekend with 250 gr Nosler BT. Most other loads are around 1.5 inches at 100 meters.

You can get another 100 fps with that bullet. I got 2450 fps with ADI 2208. The primers were still round & the bolt lift was easy. John Barsness reports 2550 fps in his CZ rifle.

I also got 2200 fps with 320 gr Woodleigh RN & 56 gr of ADI 2208. Accuracy was 1.5 inches but point of impact was 6 inches lower!

Do let us know how you get on. Any plans of "blooding" her?
