should I try the 168 LRABs?

Loaded 4 each at 68g of retumbo and 68g of h1000. Will shoot these at 300 and hopefully get some more crono readings.

Also loaded 1 each at 70,71, and 72 of retumbo for pressure/velocity check.
 
70 71 and 72 retumbo clocked in at 2900,2935,2960..no signs pressure. Will try one each at 73 74 maybe 75.

68g h1000 put 3 into 1.5" and flung one high about 3". Could have been brass issue as that round chambered harder then rest. 2800fps single digit ES.

68g retumbo shot like crap..5" group at 2800fps. Single digit ES as well. It shot .5" at 100 the other day.

68g h1000 shot 5/8" triangle at 100.

Looking like h1000 is holding the groups way it should.

More testing with retumbo at 70+ I think and fine tune this h1000 load.
