Picked up some of the 174 gr HH for my big 30, hoping to get 3500 - 3600 fps with accuracy, It'd be a heck of an elk load.
What neck interference are you using and are you crimpingover 6 inches at 500 yards just not acceptable and thats just me!

Pull the expander ball, I'm betting this will solve your problem, and as always….. LEE FCDBB Adg brass .0025 nt non coated and no crimp yet try other things first 1 step at a time.
It's seems kind of strange; only two OPS mentioned the 174HH. When I bought my Tikka T3X 300WM/1:10", I contacted Steve Davis and he recommended the 174. He said they developed it specifically for rifles with short mag boxes. Fast forward, I'm getting 1/2" groups reliably at 100 yds with 76.5 gr H4831SC at 3100 fps. Plan to use it for moose in Newfoundland this fall and elk in WY in 2024.Picked up some of the 174 gr HH for my big 30, hoping to get 3500 - 3600 fps with accuracy, It'd be a heck of an elk load.
