[QUOTE="goodgrouper, post: 109431, member: 2852"] I have now switched over to my match brass for the thunder and it weighed about 3 grains less on average than my load development cases. The load of 94.5 grains now does not shoot quite as well so I bumped up to 95.5 grains of RL22 and she is back to shooting where she does best. <font color="blue"> The new velo is 3333 with the 225 AB's and a sd of 5 fps. </font> This speed and the bc of .568 translates to just over 1 ton of energy at 1000 yards at 5000 feet elevation! The load development brass really got pounded hard and was fired upwards of 10 times with over-the-top loads and can still be used. The primer pockets provide no resistance to seating a primer but they do not fall out yet. Not bad for Remmy brass. On a side note, I set up that old bowling ball at 410 yards and shot it with the AB's the other day. WHAT A DIFFERENCE! That bullet decapitated the top half of the ball and launched it off the rock, down the mountain, and into the river below! Unfortunately, I was not able to recover it for a picture but it was a very noticeable difference in reaction than when it was shot with the MK's. [/QUOTE]
