I love CCI350, but during the Bosama The Clown scare all I could get was Wolf LPM.

I Chrono'd Wolf LPM against CC350 using a known golden 44 mag load and discovered that Wolf is much different.

240gr OT LSWC, 23.5gr H110, 10 shot strings, 4" barrel 329pd.

* CCI350 23.5 Avg=1232fps, ES=44fps - no flash
* Wolf LPM - Avg=1183fps, ES=110 - very flashy


The 23.5gr of H110 load with CCI350 is my control load and the results closely match previous chronograph work.

My assumption, based on the flash, is Wolf LPM is not hot enough for the slow powders.

Does anyone have any experience using the Wolf large pistol mag primers?

A little more information on those miserable Wolf Large Pistol Magnum primers.

270gr WFN, 4" barrel

Enforcer 19.0gr

* Wolf LPM - avg=1056fps, ES=82fps - One near squib - very inconsistent
* CCI350 - avg=1108fps, ES=37fps

2400 17.0gr

* Wolf LPM, avg=1048, ES=46 - Consistent
* CCI350, avg=1091, ES=39

AA#9 17.5gr

* Wolf LPM, avg=1043fps, ES=135fps - One very low
* CCI350, avg=1097fps, ES=9fps nice shooting


The only powder that worked OK was 2400 - which is a flake. Both Enforcer is a ball powder and AA#9 is a squashed ball powder. The fact that 2400 worked OK further confirms my suspicion that Wolf Large Pistol Magnum primers are really just regular Large Pistol primers in a different package. For 44 magnum - they suck.

I have not used Wolf LPM but used their small pistol and small rifle with no problems.

Wolf (in the small rifle at least) label their primers differently to every other manufacturer.

Magnum in Wolf primers does not mean "hotter" (at least in the small rifle), it means harder cup.

So if they have used this nomenclature across their entire range then indeed the Wolf LPM are not suitable for hard to ignite powders like H110/Win 296.

Check out Wideners for the explanation that goes with the small rifle primer types.

Ive too found them to be pretty mild. I tested them along side there standard primers and they seem to be a tad hotter but not much. No where in the same league as cci350s or for that matter any of the other mag pistol primers on the market. Id steer clear of them for powders like aa9 and 110/296.

I just measured the primers. CC1350=0.119" tall, Wolf LPM=0.116" tall.

Just a bit of trivia..

Well like you I picked some up for the most part to keep from shooting up the good stuff just for kicks.

I have only shot a limited number of them and in rifle mostly. Thanks for the heads up though as my main powder is 296 for the revolvers, so I will keep the Wolf for the lower loads shooting cast.

The SAAMI spec for large pistol primer pocket depth is 0.118-0.122". So considering the wimpy ignition system of S&W revolvers, if the right combination of deep pocket/short primer happened, would inadequate crush cause the inconsistency?
