[QUOTE="Hawk in WY, post: 1087507, member: 70947"] Success! First of all thank you to all who helped enormously with data I did not have. The Berger data looks conservative and is well below other published sources, but was very helpful. I now have three loads which will put the 145 gr. Barnes LRX bullets into just slightly over one half inch, 73.5, 74.0, and 74.5 grains of RL-22. Fed GM215M primers. 3.40 COAL (.060 off lands). Normally I would now fine tune the powder load and play with COAL but since the 74.5 grain load put five into .364, I'm done. No signs of pressure, but the absence of published data made this more difficult that it needed to be. Barnes needs to update their reloading manual. Will run this load over a chronograph in a few days and stretch it out to 1,000. I will return to 168 gr LRX load development when I'm done with this load. Now what some might not agree with is what else I did to make this fine rifle shoot to my satisfaction. I pulled a bullet because I thought seating required more effort that normal. Found the new brass and the once fired brass tumbled with pins was shaving the sides of the bullet. Chamfering the case mouth and adding a bit of powdered graphite to the inside of the neck got this rifle shooting. I realize there are many variables here, but in future I will be chamfering the case mouth of new Dakota brass and either dry tumbling after wet or using graphite on the inside of the necks with either new brass or "squeaky clean" brass from wet tumbling with pins. Hawk heading for cover. [/QUOTE]
