IMR4227 and magnum primers

[Fordtrucks]

Does anyone use regular small pistol primers with IMR4227 in the 357 magnum? Some of my books say that magnum primers are not required for IMR4227 in the 44mag but assume it's because of the large pistol primer.

Not sure if a normal spp has enough juice to get consistent and full ignition.
Just wondering what the general concensus is.
I want to shorten the list of components and if I can quit buying spmp I'd be happy.

Maybe even if I could use small RIFLE primers that would be good. They might have just a bit more juice to help with ignition if my pistol can get them to detonate. I can use softer Remington SRP as a test then move up to Cci see how that works.

Anyways, give me ur opponions. I have been in the hunt for some 2400 powder as I know that one is good with regular spp, but it's quite scarce right now.

I use mag primers with all loads. You can use them with 2400 also with excellent results.
If you have reg primers use them. Then just buy mag primers.
The rifle primers are usually a bad choice in a pistol.

I am BAD with primers. I use Tula LPP for ALL of my loads but using magnum might be better for some of the .44.

I use SRP for some pistol loads, but I gotta see how they fire. If the guns like them then I might just switch over completely.

I use 4227 with my 357 mag, but I do also use magnum primers (with good results). From what I've read it's only 2400 that you can use standard primers with.

Hmmm. I should try some of the magnum primers with my h-110 or blue dot loads. I wonder if I would still get powder flakes on my arm.

[Fordtrucks]

Wow stilly u use regular primers with H-110? I though there was as much danger with that as there was with going below minimum charges with H-110. Like an un controlled explosion or something.... double ignition chrachertistics.

I'm actually being serious BtW. Lol

I have never used Magnum primers for IMR4227 in either .45 Colt, .357 Magnum or .44 Magnum as that powder doesnt need it IMO. And my .45 Colt loads were heavy "Ruger only loads of approx 25 Gr under a 185 Gr HP for a Measured MV of 1300 FPS

I have heard some powders need a little more Oomph to get em going but IMHO IMR 4227 aint one of them.

[Fordtrucks]

Thanks for your info Noonanda.

[Divernhunter]

Stilly---Yes you really need to use mag primers with H-110 or Win296. I cannot remember a book that does not say to use them. Then sometimes my memory......

Been using LPP with IMR4227 in 44mag...working aok, no problems.

[nrgcruizer]

I used regular small & large CCI primers on my .357 mag & .44 mag. I didn't have any magnum primers at the time. I used IMR 4227. I can't tell the difference. They all went bang. May be if it was match ammo I'd care a little bit more. But they were for plinking.

[stilly]

I own like 14k LPP and maybe 1K LPM because at the time the magnums cost more. Plus I got a little penis since I load for .44 so no magnums are needed...

BUT, I have fired hundreds of Enforcer, H-110, 700-X, Blue Dot, LiL Gun, 2400, AA#7, and 4227 with only LPP and never had ANY issues. This aint a ONE TIME thing. I have ALSO fired about 100+ rounds of H-110 with LPP Loaded at 22.0GR when the starting point was 23.0gr For the longest time up front I was shooting 22.5gr with a 240gr pill and LPP and never had any issues. For the record, BoLee on P. 644 (44 remimag) states LPP.

So yeah. Put that in yer pipe and smoke it...

My choice of primer is based mostly on what is stamped on the barrel. I load in the "real deal" range for all my Magnum guns, so the Magnum primers just remove the question about what I should use. As far as supplying primers, I can appreciate wanting to avoid buying 5k just to make sense of a HAZMAT fee and then having more primers than you can project using. One has the option of paying for local supplies in smaller quantities, proportional to their use. What I won't do, given any option, is change powders to suit my primer supply.

I darn well near blew a Colt New Frontier up using standard primers with a 20 grain load of W-296 behind a 250 grain Hornady XPT bullet. Load was listed in the manual, and with magnum primers it was accurate as all get out, even took down the 200 meter rams. One fine day I grabbed the wrong tray and loaded standard primers (proving I should have read the label twice, then a third time before priming, and again afterward). When the first round went off there was a noticeable hangfire, a huge pop - boom, and substantially more recoil. I unloaded the revolver, and found a huge lump and some smaller pellets of W-296 melted together that fell out of the barrel and case. Seems the primer didn't have enough heat to fully ignite the powder, but what powder did ignite forced the bullet into the barrel, the the rest lit off and pressure went all nuts. That pressure fused the unburned powder which became a plug, but didn't burn. Hornady subsequently removed that load from the manuals, must have been too many cross-eyed handloaders out there.

Lesson: Check what you have in your hand, is it the component listed in the recipe? Eyes play tricks, then the brain fills in, and you see what you want. Ever reach for a can of peas on the grocery shelf and wind up with green beans at home? Then never vary in the recipe - period. W-296 (same stuff as H-110 in a different canister) need two things for proper ignition: Magnum primers and a heavy roll crimp. IMR-4227 isn't as finicky as W-296, but always use the primer strength called for in the recipe. In the .44 Magnum, .45 Colt and .480 Ruger, it produces fine accuracy, but at a reduced velocity.

Another similar powder to IMR-4227 is Accurate 1680, a clone of the old W-680. In certain magnums this is an accuracy powder, especially the .357 Maximum ( CCI 450magnum primer), the .454 Casull, .460 and .500 S&W (all WLR standard primers). It was far and away the best powder in the .357 Maximum, winning me a bunch of IHMSA revolver trophies (they are somewhere in a box of dust in the green-room closet, not as important as they once were).

I'm a lemming, I follow whatever loading book I am using that day, be it Lee, Hornady, Hodgdon, Sierra, Speer, Nosler, etc. If it calls for Mag primers, it get's Mag primers.
