[QUOTE="bushmotornv, post: 1579378, member: 72331"] I am relatively new here but,I have 400 Bertram cases in 338 RUM. Out of those,I only had 54 cases that weighed within 4 grains. The neck thickness averaged .004" with many above .0065". Case heads were all out of square by a minimum of.005"+. Case heads being out of square causes extractor engagement issues,if the case enters the chamber on the high side the extractor won't engage the rim. By comparison,150 pieces of ADG of the same lot number,all weighed within 1.6 grains,and neck thickness is all within .0007".There may be those that say that is too much work or being too critical,but you only get out of it what you put into it! And,the ADG is very reasonably priced IMO compared to Nosler or Norma,the latter needing forming to 338 RUM. No,i havent shot any yet,barrel is in the lathe as we speak. [/QUOTE]
