Not a good signal for an ammo to fail in firearm that is has otherwise been !00%.
When I purchased my "old" Herters a few days ago the ammo guy said "new" Herters was made by Winchester. WWB (Winchester white box) is not on the A-list for very many shooters. My poor test and your cycle prob... ghost/clones of WWB?
Pretty sure that it is winchester - the lot number format is the same as winchester - only tried 2 boxes of it in .45 & it ran flawlessly and was accurate. i wonder how the brass is for reloading - if it is Winchester then probably fine for that- headstamp on this stuff is *USA* - actually "star"USA"star"
Shot a box of "old" Herter's by S&B, and a box of 'new" Herters' made in USA with my 995ts.
Shot 10 rounds of old (top pic) then another 10 of new (bottom pic.)
Alternated between the two version every 10 shots until all 100 were shot.
Bench w/ simple support, just 25yrds, Not going for gold... just as consistent as I could get for a simple test.
Icky results. Will test another box of each another day.
Tested old vs. new Herter's again (9mm, FMJ, 115). Shot 30 rnds of each in groups of 10. Results were rather similar this time, unlike the testing of a couple of months ago (in post #14). ??? My groups were not so good that day... prob my fault. Will test again. But this is pic is typical of the test ('old' on top).
