I loaded up some h4831sc 57 gr made my o.a.l. .010 longer and shot a three shot group at 1.2. I am still .030 off my lands i dont know if i should seat out or in. Can rifles shoot better with a short seating depth? That is with cci 200 primers. :
I have been working with the 140 ac and reloader 19 and the best shot group i can get is .932 at 100 yards. Do you think i could tighten it up a bit with seating depth. That is out of my 270 win.
I have a ruger 270 m77 and 130 gr accubonds i came up with a seating depth of 3.189 does this sound like it is seated to deep. the nosler s.a.a.mi. overall calls for 3.340 max so i was wondering if i had them seated to deep and was worried about pressure
what is a good load with 130 gr accubond in a 270 winchester. I just bought some 130 gr bullets along with H4831sc powder i was wondering if any body had tried this combination
