Re: 6mm cm long range load development.

The way I was taught to do load development by my mentor:

Find the powder and bullet which it sounds like you have, chrono it and check es, sd(single digits). Play with seating depth and see if you can do any better. Print groups as far as you can see the group develop. For me it is 300yds with the optics and range I shoot at. Don't just shoot one group of five, shoot four groups of five. You will get a better idea of what the rifle actually will average. The first time I watched my mentor do this it was only a couple hours at the range. He had a load worked up for his comp gun. A portable press is very handy for load development and matches like the NBRSA Nationals in Calif. where you can get six days of shooting.

Re: 6mm cm long range load development.

Up date on 6cm load. Chronographed some loads 49 grains h1000. Showed 2950 fps with an es of 16 fps. My and my brother took it out yesterday and shot steel at 500.them 800. Them 1000. Made first round hits at 500 and 800. Had to lower my fps bye 15 in shooter to hit at 1000. After that it was easy ten inch gong rang a lot. It was a great day and iam ready to do it again.
