I took my m305 18.5" out for the first time yesterday. Shot about 60rnd in total. 40 @ 25yrds with VG results (for me). However, I only managed to get 5rnds out of 20 on paper (24"x24") at 100yrds with the stock irons off the bench. I can't wait to go back and give it another go!
All I can add is I had a blast and I'd take a crappy shooting session @ the range over a good day @ the office anytime…..
