Finally got to take mine out today. Put 85 rounds of various ammo through it before the rain started. Took all of 8 rounds of AE to get it rough sited at 100. Wouldn't have taken that many, but I forgot to treat it like an AR, and bore site the upper. The AE didn't impress me with accuracy, but I know that's what they use to test fire the rifle, and it's cheap to rough site with. Next I decided to try some Winchester 150gr PowerMax. First three rounds went into pretty much one enlarged hole. Then I screwed it up cause I got all excited and pulled the next 2 rounds. I wanted to try the Winchester cause my M-305 seems to really like it, and let's face it it's cheap. I still think that it's got potential for a good hunting round, even though it's not "Match" ammo. Tried some 150gr and 165gr Hornady SST hand loads. I kept getting those 3 round groups, and can't get the fourth and fifth to go where I want them to. I can't blame the gun for my inadequacies. Hopefully as the gun gets broke in, and I get used to the scope, trigger, etc. they'll get better and tighten up.
