i just in from putting 50 rounds of cheap walmart remington thunderbolt thru the rifle...or should i say...47 rounds.
i had 3 ftf stovepipes (all occurred after firing a round. all ended up nose of bullet above the chamber with a very smashed bullet).
adding oil to the gun and more rounds helped cure this, a bit. i think the bolt is moving farward too slowly and is allowing the cartridge to tip up too much as it is stripped from the magazine.
using the awesome zeiss zfk 4 x 25 scope and a VERY POOR KNEELING POSITION (unsupported, no sling) i could easily hold 3" at 50m. with a more solid position, i think it will easily group well below 2".
the trigger has a mile of take up, but is surprisingly good at let off...pretty light and fairly crisp. none the less, i wil be installing a red star arms match trigger group shortly...i like my rimfires as accurate as possible.
with irons, i was all over the map! man, the light was fading fast and i was having a difficult time getting a sharp front sight AND a steady window for the shot release from my half assed shooting position. i shot two bulls of 10 rounds each and all shots were in a 5" group...not very good shooting on my part.
next trip out, i'm going to try it rested, just to see were this rifle really shoots.
btw, looking at the plastic bolt buffer thingie, it looks as if the rear of the bolt does not ever recoil far enough to come into contact with it.
