Primers for 4227

[ejcrist]

I want to try 4227 in a couple of wheelguns I have (32 H&R, 44 Special, 44 Mag, and 45 Colt) but don't have any load data details in any of my manuals. I found load data on the web of course but with regard to primers I couldn't find consistent info; some use magnum primers while others stick with standard primers for the cartridges listed. Is there any consensus on mag primers vs. regular for these rounds? I'm guessing regular primers for 32 H&R but I don't know about the 44's and 45. Any info would be appreciated.

Thanks, Gene

I use Winchester Large Pistol primers for all my large primer pistol loads. No worries.

These are not my loads, so use your own judgement about these.

Thanks for the info - definitely appreciated. From what I've seen so far there's more load recommendations with regular primers than magnum. The only info I've seen so far recommending magnum primers was individual pet loads. so I believe I'll start with regular primers and adjust from there if necessary.

I am using 13g of IMR 4227, with CCI large pistol primers, and am very happy with this load in the .44 sp. The load claims to be 947 fps with a 12600 c.u. p. rating. I shoot it out of a Flat top Ruger Bisley.
I don't know why I did not use it in the .45 lc, I guess maybe it is because they were already loaded with W231. (fires real dirty) I still use the CCI LPP in them also.

I use Win standard primers in almost all my loads . never had any problems , but i do not make reduced loads with Win 296 or H 110 . starting loads and up .

ive never tried 4227 in 44spl/mag or 45 lc but I do use it in 32 h&r and 327 fed mag . for 32 h&R I load 9.5 gr under a .314 90 gr swc bullet from a lee mold with a standard primer .it shoots good but is very dirty .max for 32 h&r is 10 gr according to the reloading pages of md smith. I also use 4227 in 357 mag on occasion .I got lucky a while back and ran across 4 lb of this powder in a local gunshop as new old stock for 15.95 a lb so I grabbed all of it .

Thanks Sandman - that's good info to know. I've read a lot of good things about 4227 and the 32 H&R so I really wanted to give it a go.

I have loaded 4227 in 32-20, 38, 357 & 45 Colt. I have gone to magnum primers in the heavier loads, the result is less powder residue. My preferred loads involve a compressed charge behind a heavy wadcutter lit with a magnum primer.

[Radarsonwheels]

4227 and accurate #9 are my go-to powders for reduced magnums for when I want more than a special but not H-110. I use standard primers. I don't see a lot of unburned powder unless the loads get too low.

No need for a mag primer at all. But I will never use 4227 in the .44 mag again.
I shoot 296 in the .45 Colt with standard primers. WW will work.
SP mag primers are different so they are good to go in the .357, etc.

Just curious, 44man, why won't you use 4227 in the .44 Mag again? I burned a few pounds of it a while back, and had excellent accuracy. I did have some powder residue in the bore, though.

I shot IHMSA and started with the 4227's like all the others on the line. I got super groups at 200 meters and thought I could clean 40 targets easy. Not to be, as the gun warmed things went to pot. Velocity kept going up and I hit lower and lower. Primers got real flat.
when I got to 200 meters I was 16 clicks over normal and still hit 50 meters short. 296 cured it and I started shooting 40's.
It still hurts me when anyone recommends 4227 for the .44.

What was this caused by--a barrel-time/recoil-arc anomaly? Interesting, in any event.

I use 4227 in some of my 300 AAC rounds that I are still under development. I have had no issues with standard SR Winchester primers.

[Cornbread]

I use CCI 300 primers with 4227 in 45 colt ruger only loads and get really good ignition and accuracy with that combo out of my 45 colt blackhawk.

Seemed as the gun got hot, the power burned faster.

My apologies, lack of question clarity on my part--I was seeking your view on the targeting anomaly, i.e. the lowering bullet strikes as firing continued. My thoughts are that as velocity picked up, "barrel time" decreased, and bullet exited at a lower point in the barrel's upward recoil arc.

Exactly what happened. Shot cool and the powder worked fine and a shot at a deer would be OK. Why it worked in a very hot .357 max confuses me. Must be case capacity. Most on the line used 25 gr with a 240 gr bullet. I dropped to 21 and had the same problems. Seems heat is the cause. 296 cured it right off. Then I found 296 does not like a mag primer, cut groups by 2/3's with Fed 150 or CCI 300's.
