[QUOTE="Jason.N, post: 2608893, member: 124144"] I've got about 90 rounds down with mine. Picked up about 10-20 fps from the first trip. I loaded up some hornady 105s with varget and starline brass. 25-27 grain in .5 grain increments. I was g2g at 26.5 and hit good pressure and 2 of 5 blown primers at 27 grains. I did have to adjust the gas block up and down. At 26 grains the gas was just right and 27 where i hit obvious pressure it was also over gassed. I think both contributed to the pressure signs. Next round i will try 25.5-26.5 in .2 grain increments. Barrel is still speeding up so whatever node i find will likely change again. I have also have been loading them at factory legnth. Once fully sped up i will do a seating depth test. Another note - my sd's have been fluctuating from 5-20 on 5 shot groups. Hopefully i can find a solid speed and sd node along the way. For those that have hundreds of rounds in there barrels- how many rounds til your speed plateau'd ? [/QUOTE]
