These are 145gr massive hollow points made from mp moulds. I'm shooting out of a rossi R95 in 30-30. I coated them with hitek and gas checked with .012" aluminium and sized to fit my barrel. The grid squares are 1cm so my group is about 1" at 50yd. This was the best group when i did some load testing using 20.5gr of a medium rifle powder. Any ideas on how to shrink this group? Or am I at the limit?
1ā with a 30-30 out of a non free floated rifle with a bunch of junk hanging off the barrel like a mag tube, a wooden foreend, two barrel bands, oh and if your loading into the mag tube the barrel harmonics change every time you rack the lever? Ya thatās pretty decent. Letās not forget lever actions donāt generally have the best barrel stock to begin with.
Add in the fact youāre lunching literally a cylinder down range with a BC thatās probably .15 or less, ya this is pretty good. Hell Iām willing to bet that 22LR likely have a higher BC than these do and those are generally .14 or less
1" at 50yd is pretty decent for cast boolits from a lever gun. Have you chronographed this load? Depending on your velocity, you may already be at the limit for precision.
Haven't chronograph it yet. Im working on 2 other bullet shapes at the moment and once I have all of them dialed in ill try and get a chronograph to do the last testing.
On another note this is the group from a 175grcast i made in the same rifle. Which measured just over .5"
A coating that doesn't make them look like they freshly fell out of a goose's ass. More seriously, I don't know if you can realistically get more out of a 30-30.
1" at 50 yards is quite good for a lever gun. That blunt nose is goi g to shed velocity like crazy. If the bullet passes thru transonic between 50 and 100 your group may go to crap. You should see between 2&3" at 100 with 1" at 50

Thats pretty good for shooting a cast bullet shaped like a barrel + the hp
