Mostly I use once fired range brass that has been tumbled and the primer pocket cleaned. Ive found that Win LPP tend to either seat to loose in the pocket or are too big to fit. Most of the problem seating seems to be in once fired Win brass as well. Overall about 9/100 have this problem. Out of 1000 primers thats 90/1000 that don’t work. I mostly use CCI LPP and have had ZERO problems. For price and quality Ill stick with CCI.

Had a number of failure to detonate primers in 1000 rounds (5). Happened in an XD (2) and S&W 625 (3). All primers had a good primer strike dent centered on the primer. Other rounds (both reloads with other primers and factory loads) did not have any problems.

I’m a very serious shooter and loader and have had a lot of experience with Winchester Large Pistol primers. When ever I have a light primer strike it is with Winchester primers. The striker spring is new and striker channel clean. The primer is seated deep enough. Seems like lately some lots are better than other lots. It is a knew fact if you have a comp gun with a lighter striker spring use Federal primer because they are softer . I only buy Winchester if that is all that can be had. I don’t use lighter springs in my pistols

I suspect that these primers are more sensitive, in the packaged state, to humidity, temperature and contamination than other primers. Loaded 100 .45 LC and had three misfires, 100 .45 ACP and had three or four misfires. Before using them, I stored them in a secure closet in the garage that is not air conditioned. Also, my auto prime broke so they were primed one at a time by hand and it was HOT where I was loading. The combination of a humid Florida summer and sweaty fingers were probably the culprits. Incidentally, Remington primers stored under the same conditions have not been problematic.

Have loaded around 2000 45acp with these. Usually have about 1-3 per 100 rounds that don’t fire even with a good primer strike. Put it in another 1911 and it goes bang. Use for target and IDPA

I like the fact that it’s both large pistol/magnum pistol friendly. I prefer CCI but have not had issues with Winchester primers in the past.

I’ll use CCI when I can’t find Winchester primers. They always seat easily and never a misfire.

I have used Winchester primers for 25 years, about 90k rounds reloaded. There have been 2 FTF rounds in that time that were faulty primers for the Large Pistol primers. Autopsies of said rounds revealed the cause. Not perfect, but excellent.
