CCI Std vs. Magnum Primers - Follow-Up Question

[GypsmJim]

I realize this has been asked before. I just wanted to get an updated answer.

Background - NY is now requiring a NICS check to buy ammo. So far it has been a disaster. The scuttlebutt is that primers and powder might be next.

I DON"T buy ammo. My rimfire supply will last me forever. I have adequate powder. My only future issues are primers.

I have a supply to last me at least 3 more years. But, at age 74 I'm now close to being able to get a lifetime supply. (it might take a couple SS checks, but who cares.....LOL.)

I have a source to get SPP at a "reasonable" price, but they only have Magnum LPP. Obviously, with hazmat charges I would like to buy ALL my needs at once.

I Load 41 mag, 41 spl, 45 acp and 45 Colt. Those are my only LPP needs. None are loaded hot, just target loads. I have enough regular LPP for 45 Colt Hunting loads, so I can keep my Ruger only loads separate.

My question is: For my target loads can I substitute Magnum LPP without any issues, or should I have to go thru a test program to see if there is a problem?

They should work just fine. If you want to really get precise, you might consider re-working / re-developing your load, but that may not be necessary at all. I've substituted without doing any new development and all has worked okay.

Yes. A widely discussed topic here. If it will fire in your handgun reliably, it will be OK. Winchester LPM and LP primers are identical. I think primers from other makers are labeled differently, but their performances are essentially identical.

Like said above, there should be no problem. As usual, drop your load back a bit and work back up but in reality unless you are at max charge weights you will see little to no difference.

The biggest difference you'll find between standard and magnum primers is that the magnum primers will point out which loads you're using that aren't very efficient.

Some powders tend to do better/burn better at certain pressure ranges. Don't know how many times I've read that powder xyz does better when the loads are at the top end of the reloading data.

A chronograph will pick up on this. On another website there's a guy that does pressure testing. He tested different 9mm loads (mag vs standard) using starting loads. The end results were that fast-burning powders like bullseye were unaffected by the standard vs mag primers. Slower burning powders like unique showed improvements with the mag primers.

Most look at those improvements and think that "I have lower my loads by +/- 1gr and rework them". In reality the unaffected loads are burning 90%+ efficient. The affected loads are safe and simply burning more efficiently.

Years ago when I hunted with revolvers I'd cast my own bullets and work up hunting loads with them. There were always 2 tests I'd do with them after finding what I considered an accurate load. I'd increase/decrease the hardness/alloy the cast bullet was made with looking for increases in velocity while maintaining accuracy. The second test was to switch to magnum primers if I was using a standard primer. Again looking for improvements in accuracy, velocity & changes in sd's/es's.

There seems to be very little difference in pressure generation between standard and magnum primers. Magnum primers may actually make the combustion of medium burning rate powders a little better. My advice is that if you are loading to maximum safe pressure levels with standard primers, then it is wise to back off a few tenths of a grain and work up to maximum safe with the magnum primers. If you are loading to less than maximum safe pressures, then the magnum primers are not going to create ammo that exceeds safe pressure.

Winchester LPM and LP primers are identical.

Winchester, like Remington, only makes one style of large pistol primers.

Thanks to all for the comments about magnum primers. As it turned out the supply dwindled.

NOW, I have a chance to get some FIOCCHI regular LPP. Never tired them before. What say y'all? Good, Bad or Ugly?

I got a great deal on 1,500 Fiocchi SPPs and they work great in my 9mm loads.

Only drawback is they are packed 150 to a tray in an asymmetrical layout, rows of 9 except the last one, so you need to pick some out (or put some back) if you want to dump an even 50 or 100.

I haven't heard anything negative about Fiocchi primers, but never reloaded with them. Have shot a fair amount of their loaded ammo with no complaints at all.

The best approach when switching to Magnum primers over standard primers is, do another load work up. Start new, from basic reloading manual data and develop a load that suits you and your gun. I too have a decent inventory of components and I like reloading so a new load work up is just more fun in my shop...

Certainly the very best advice, but I don't think most handloaders would bother with a new load workup. Sometimes it can make a difference, though.

Fiocchi Primers are just fine Back when Alcan was in business they made Alcan primers. They then made S&W primers too. I've used and sold bunches...

Why don't you just take a vacation to a um.....friendlier state and pick up some trinkets.

Just sayin

Good idea. Now tell me which state has CCI pistol primers sold over the counter at prices that are inflated, but not gouging.

I'm in NY and they are now just starting to appear, with no hassle buying them, except that the flavors are not what I've been using for the past 50 years. Hence my questions.

BTW, thanks to all that responded to my questions. Now I am confident that I know what to do.

I like Fiocchi primers a lot. They are a very good product, reliable and clean too. Back when the crunch started I bought a bunch and was happy with the results. I wish I would have bought many more.

I like reloading (I don't reload for $$$, nor rare cartridges, max velocities. odd component pairing, etc. I reload because I like reloading.). If most handloaders won't do a workup or use some internet "formula", I figger that's fine. Doing a work up is just added fun for me. I have seen differences when changing components, some drastic and some (many) slight. One enjoyable part of handoading is analyzing the results. I record all my handloads so I can bring out past load data/results and compare. If I was just reloading for ammo to go bang, I'd probably give it up and invest in factory fodder...

Yes, I find load development is the most fascinating part of handloading, but some don't really enjoy handloading as a hobby in itself and that's okay. We all have different perspectives; it just seems a handloader that doesn't experiment misses out on a lot.
