So after 3 days of load development I have officially concluded that I am going to be sticking with Sierra 107grn Bullets......I think

.... until I get a chance to try some Bergers perhaps?!?!
The top speed I could get the Lapua 105's up to was 2860fps (avg of 5 shot group) with 31.1grns of Varget and seated kissing the lands. More powder (31.3grns) just made for slower velocities by 20fps
I took the Sierra 107's out tonight and here are my results:
2 different sets of loads, both tested at 100m
Seated Kissing the Lands:
30.5g Varget - 2860fps - ES 8 - Group .554
30.7g Varget - 2874fps - ES 26 - Group .357
30.9g Varget - 2896fps - ES 15 - Group .574
31.1g Varget - 2923fps* - ES 21* - Group .688
31.4g Varget - 2922fps - ES 33 - Group .606
Seated 0.015 into the lands:
30.5g Varget - 2871fps - ES 21 - Group .333
30.7g Varget - 2886fps - ES 17 - Group ..604
30.9g Varget - 2915fps - ES 17 - Group .419
31.1g Varget - 2934fps* - ES 6* - Group .790
31.4g Varget - 2940fps* - ES 10* - Group .487
* - Total of 4 shots recorded due to either user or electronic errors
