Yes they have caused a few problems for our club members and myself . cci450 i have problem with in omark 223 Omark 308 and savage 223 ,308 all had plenty of firing pin contact but faild to ignite

I thought I was as I had one not fire in the 308 then had a bunch of issues in the 6mm. Turned out that my 8 month old sucking on a 308 case had done it no good and the 6mm was just the joys of fire forming from 6br to Dasher. Bit of a relief as I have 8000 CCI450s in the safe

Trev I have fired several thousand 450’s with my barnard in the last couple of years without issue, I have just started using a new lot no in the last few weeks I can check it for you if you like.

A member from my club had issues with 450's at a prize meeting, where he had nearly 20 miss fires and tried another bolt before giving it away... He ended up giving me that brick of 450's.. My young bloke has been using them all year in his dasher and hasn't had a single miss fire...

[Barry Davies]

Insufficient striker energy and/or striker protrusion or too much head space.

In my Dasher after hydro forming yes headspace is an issue, but my 308s l just bump the shoulder down 1 to 2.5 thou on a fired case after a little spring back.

The 450's dont have a problem like the Br's any isuses with 450 is probably headspace. I have fired thousands and thousands without a single issue. Those having issues are you full length resizing? My guess is yes and you are getting head space wrong.
