Mike C Posted January 1, 2023 Report Share Posted January 1, 2023 I'm running out of my trusty Murom KVB-223 primers which I've used solely for my 6.5CM for a while now without any problems at all and they were on the 'hot' side. Obviously I won't be finding any of these again any time soon so, Q: has anyone had any experience with PMC standard small rifle primers which I have a good amount of ? Or do I just swop over to Federal 205M Quote Link to comment Share on other sites More sharing options...
Nick 53 Posted January 1, 2023 Report Share Posted January 1, 2023 I think there’s quite a few people running out of trusted primers! It might be worth looking for alternatives and unfortunately re doing your load development once you’ve found a alternative buy in bulk if you can ive done this buying in bulk but alternative primers will be required! and load development needed nick Quote Link to comment Share on other sites More sharing options...
Richiew Posted January 1, 2023 Report Share Posted January 1, 2023 At the moment I’d settle for whatever is available. Stocked up a while back with cci and federal so should be good for the new year. Quote Link to comment Share on other sites More sharing options...
Scotch_egg Posted January 1, 2023 Report Share Posted January 1, 2023 Be prepared for a shock when you see the price of primers. If you find them in stock that is. Quote Link to comment Share on other sites More sharing options...
Catch-22 Posted January 1, 2023 Report Share Posted January 1, 2023 PMC, and Wolf, are the same as Murom…same factory. Quote Link to comment Share on other sites More sharing options...

PMC SRs are Murom KVB-223 from a generation back. They are very well made and 'mild', but if they have unplated copper colour cups, they are very fragile and prone to 'blanking'. Depending on your rifle's firing pin and its fit in the bolt-face allied to the load you're using, results will likely either be excellent or unusable.

The Gun Pimp Posted January 1, 2023 Report Share Posted January 1, 2023 Laurie I remember, we started using them in 6PPC but every time one 'blanked' - pierced - the case was scrap - no way of removing the primer. Annoying with a fire-formed, neck-turned Lapua 220 Russian case....... Quote Link to comment Share on other sites More sharing options...
Mike C Posted January 1, 2023 Author Report Share Posted January 1, 2023 Well going off those comments I think I'll save on potential issue's down the line and use Federal 205's instead, got plenty of em 🙂. I shall appoint the PMC's to something less demanding. Thanks for the comments 👍 Quote Link to comment Share on other sites More sharing options...

I'm using my remaining stocks up in 120/123gn 6.5Grendel handloads for a Howa 1500 'Mini' Oryx rifle. They're ideal for that, likewise 222 Rem and mild 223 Rem loads.

Brillo Posted January 18, 2023 Report Share Posted January 18, 2023 If you can get them, a good alternatives are Magtech and Fiocchi. I seem to recall that Laurie rated the former very highly in his SR primer review a few years ago. Quote Link to comment Share on other sites More sharing options...
Mike C Posted January 26, 2023 Author Report Share Posted January 26, 2023 For what it's worth. I managed to sneek a day off and go up to the range last Tuesday morning to do a quick test using Federal 205m primers and compare with my archived murom kvb 223 test results from a few years/800 rounds-ish back. Rifle is a tikka tac A1 6.5cm, lapua sr brass, N160. Temperature was around 8C (very mild for the time of year) and very little, if any, wind. Standard harris type bipod and rear bean bag. I did the following tests at 100yrd: Firstly for safety, a single round going up in 0.5gr increments from my lower node charge weight up to my higher node charge weight to check for signs of pressure. No over pressure signs so on to my mini test. 3x rounds at my usual highest node powder charge: 8.5mm group. 3x at -0.3gr: 7.5mm group. And then: 3x rounds at my 2nd node down: 5mm 3x rounds at +0.3gr: 10mm 3x rounds at - 0.3gr: 5mm Comparing the groups with one's done using murom kvb 223 primers some 2 years back it appears the 2nd node down has shifted ever so slightly down in powder charge some 0.2gr if that. The higher node has spread out by around 2mm and again shifted slightly down on powder charge. So for my rifle, Tikka Tac A1, changing from Murom kvb223 to federal 205m primers will mean reducing my charges down by 0.2gr to stay in the sweet spots. However what I haven't managed to do yet is measure muzzle velocity for consistency and I only did 3 shot groups and not 5 like I should have done but bullets, powder, primers etc are getting bloomin expensive.
