Finally I can also share my load on here. Turns out, my inability to shoot well with a 4MOA Fastfire II caused the horrific groups I previously shot with my 24" Browning 71. Now it's wearing the Lyman peep sight again. Today I shot two sub-MOA groups at 100m with a .358 Sierra Pro Hunter sized to .348 over 54 grains of VV N140 with Starline brass and CCI standard primers. I was tempted to send it down the road recently, but with these results, I'll have to give it another try.
