[QUOTE="DaveB, post: 5627836, member: 5958"] The procedure to follow is : any time you change a component you need to reload at the lowest recommended level and build back to your desired or best available accuracy. If you change from SR regular to SRM primers you should have started at the very low end of the powder charge scale. Flattened primers are an indication of over-pressure. The issue is worthy of research on your part just to insure you know the exact cause. For example, if the only difference in 223 loads is the Magnum primer and you have flat primers and did not have before, we can confidently blame the magnum primer. Have you noticed any increase in recoil? Muzzle blast? Sticky bolt lift or stovepipes or ejecting brass to the next county? Look at the SRM fired brass neck for splitting. The SRM fired brass primer pocket compared to a fired SR primer pocket from same rifle you see a carbon residue difference? My experience says you will see a difference in POI. You need to watch for any signs of overpressure beyond flattened primers. Be careful as you approach the max load. [/QUOTE]
