I have one that is real accurate for me .
I use the Hornady 300 g. XTP or an Accurate molds 43-300 .
Both loads use 2400 as the powder .
Best 3 shot group at 50 yds. was 3/8" .
Average group is 1/2" at 50 yds.These are with a scope off a rest groups .
Thanks , Steve
Took mine to the range twice, shot it very little because when I did it placed one shot on top of another. Love this little gun! Hornady factory ammo, packed away in the safe somewhere, forgive me I don't have the specifics--240 gr. I know.
