yea with a 28" barrel id say it prolly was a little fast. however im shooting a 24" barrel. gonna load some in a few minutes and find out what itll do. i still have a little 4831 for my 100gr nbt, but was gonna try the 17 in 75gr vmax and 85gr nbts. hoping its not to fast for the smaller bullets with the 24" barrel. ill post some results tonight.
