Flame pattern and intensity (duration) will be different. I'd suggest dropping a grain from your present load to compensated for it.I am very fortunate to have at least 1000 primers in all of the versions I use except for small rifle match which I let myself get low on. Guess I will find out how much, if any, difference there is when using regular primers in my target .223's. No such thing as buying primers of any kind and powder is almost as bad. Think it may be 6 months plus before it gets better.
So true. Even sworn-off-for-life ex-reloader TTSH is taking note of the value of reloading components (especially SP primers) and will be investing in same if/when sanity ever returns to the reloading marketplace. Even for a non-reloader like me, owning reloading components represents the ultimate security against the ammunition taxers and prohibitionists. 😎LOL....
Around these parts, components are more valuable than gold doubloons.
A feller can find gold & silver at every turn, primers, powder and bullets are not to be had.
I bought a thousand small rifle primers a couple years ago, anticipating that I might start loading 223. I never did, but still have the primers. Figure I could trade for small pistol or in a pinch use as suchi + many others have been safely using small rifle primers for pistol reloads for decades -
