Thread: Trying something, Eric Cortina method of load development

ok bud..following you so far....now an OLD SCHOOL way of doing same....use your cleaning rod with the, object removing bit on end..eg flat end....push a projectile up the chamber and hold it as far in as it will go...may need pencil...or indeed you could just seat one only just in case and hold it in place...poke cleaning rod down from muzzle and mark rod at muzzle.remove case replace bolt,close bolt and reinsert your cleaning rod right down to bolt face,again mark...the distance between your two marks is now.............pretty darn close to your other measurement...its your maximum OVERALL length.....which in my poohseventy is no bloody use to me at all as a 130grn ballistic tip will be JUST in case mouth and no way in hell will it fit in mag....so all my rounds are made 1mm short of mag length and thats it...
