ChrisF Posted November 16, 2017 Author Report Share Posted November 16, 2017 This was only 10 rds of each , but will do more to bring it to 50 - 100 total , and see if their is any real difference . But on the above data , even with out grouping it , the winner for me is the STD , as its SD is the best , and its 1/3 to 1/2 the price of the Suppressor/Subsonic here in NZ . Remember that this thru a bolt action rifle , if you run this thru a semi-auto the speeds will be approx 70 fps less , mainly due to larger chamber spec , which would mean it the STD ammo would be subsonic .
