FX FX Maverick Sniper .22 Tune for H&N 34gr

Make sure you aren't putting too much air behind them. HUH???? Yep, too much air out the muzzle destabilizes the slug. I got this from Matt Gruber (sp??). Start backing off the HSA in little tiny increments to find the sweet spot, I'm thinking your speeds are too low but you may be maxed out. Try a lighter slug, more speed and close to the same FPE, likely better stability in the process. Been there, done that.
