Win. small pistol primers

[marshall623]

Anyone use these , I located a brick of them ( standard )and wanted some feed back before I buy . I use mostly CCI. And Fed how do the Win. Shoot compared to CCI &Fed. I, m loading 357 MAG. IN GP 100 & 10" contender using blue dot and will have soon H110 or 300 MP.

I prefer Winchester over CCI and the aluminum metallic fuel in the mix seems to produce more uniform velocities and reduce temperature sensitivity, particularly with spheroidal powders, for which they are designed.

Similar performance to the government primers in M882 Ball. Winchester standard primers perform about the same as CCI magnums.

Might want to use mag primers with the 110, I use both CCI & Winchester & both are very reliable, plus I don't notice any performance difference!

I have been using Winchester, Remington, CCI, and Federal recently(last 3-4 months). The only difference I can tell is Federal is somewhat easier to set off if you have a light hammer spring. They also seat a bit easier, I suspect due to a softer shell.
I can find no other differences in performance or accuracy. I suspect I am not a good enough shot to tell any accuracy difference between them. My chrono doesn't show any significant differences between them either, however I use mixed brass so a minor difference would not show up.

My experience with Winchester primers in the .357 mag with Blue Dot and 2400 is I get 70-90 fps less velocity than Federal SP's and larger sd's. Not my preference. YMMV

They work well for me.

This isnt exactly data from a .357 magnum but... a 3 grain charge in 380 cases with one loaded with cci and one with a winchester. The winchester produced a 22fps average higher velocity. Never had a problem with them in general used thousands.

Winchester has been my go to primer for over 25 years.. I use Federals only for light hammer tuned Revolvers.. RP, CCI, magtech, Tula are all okay if I can't get Winchesters... Tula's seem to be a bit oversized... and sometimes hard to seat.. and are in general a harder primer to ignite, They all tend to go bang in the right circumstances..

[marshall623]

Thanks for all the reply post, that the info I was looking for

[bobthenailer]

Federal are my go to primers with Winchester and CCI are my second choice, never had any problems with any of them, Ive shot around 300K of those 3 brands of primers.over the last 45 years.
Just work up the load with what ever primer brand you like

I prefer Winchester primers. I like Federals for my light strike revolver, but Winchesters have been working as well. I will not buy CCI, too hard, too many FTF with hard primers. I've only used Remington small rifle primers.

WSPs.
My go to primer in the 22 Hornet.....dale

Awhile back on the CBA site, there was a disscussion on filler use on some reduced powder charges. Ed Harris had mentioned that he does not use a filler but prefers Winchester primers because they produce a better flame and that flame fans out better in the case.(IIRCC)

I use both cci and winchester primers in my pistol loads. Havent noticed any accuracy differences but thats just me. I like em both.
