Pulled out of the safe a few weeks ago and finally cast some boolits for it. 180g truncated cone, 235gr rnfp from a Heavy Metal mold (HM2) that has been a stellar performer in other guns, and a 358318 HP mould probably about 230gr.
Put gas checks on them and then powder coated them with Smokes Traffic purple. Ran thru the Star again to re-size and put some lube in the grooves. Then loaded up some re-formed '06 cases with 41.5gr AA2495.
Shot the 180 first at our 150 meter gong using a bench, but no res but my arms. Awful trigger pull, but three shots had two nearly touching at 2 o'clock and the third about 3" away. Went to the 235's and aimed at the left edge of the gong. First shot in the center!! Adjusted scope to hopefully bring group to center. Second shot hit center and made one large smear. Third shot was also in the center!! Shooting better than factory ammo.
HP boolits hit about 3" high of center with two in one tiny smear and the third about 2" out. Durn trigger.
All in all, good day. I was impressed with the performance, since factory ammo was maybe 2-3" at 100 yds and these beat that at 165 yds. Velocity was probably in the neighborhood of 2000fps.
