today- I did not touch the swinglock die after yesterday's slightly adjusting during as session that showed some accuracy promise after increasing the bullet per bore fit just a tad. yesterday after the adjustment I would guess say hankin's 275be style loading around 5-10lbs..... for the 327mh/I4198 @ 73.0gns --speeds were approx. 2670fps area-triangle group roughly @ 1.360"@200yds
today die untouched & gun I was surprised by loading resistance from yesterday to today & it was all 3 shots(bore approx. 50 un cleaned)-very firm guessing around 50-60lbs down the tube thought we were going to have a flier so to speak of...thing was speeds were down to approx. 2640fps & 1st 2 were touching with the 3rd vertical stringing upwards to make this group approx. 1.287 with an overnight/overlaying target.
marked with black marker vertical in nature
this is a good average groups size for this powder/barrel & 327mh bullet & I like this consistency day-in/day-out but probably will not take wood @ ky's shoot but this gun is returning with some accuracy from the past.
weird-so what the difference In loading pressure all the sudden-same box of bullets/etc?? I have no clue??? temp's & humidity were close to same.
oh well another brief moment on the range!
