	Yesterday at the range I had multiple rounds fail to ignite the powder charge and it's got me stumped. About 50 percent failed and I either had to tap the from the bore or they landed in a puddle about ten yards down range. Here's the load data. Shiloh 74 sharps in .50-70 lyman 515141 450gr bullet spg lube 36.0 grs of imr 3031 winchester lg pistol primer for std or mag bertram brass Range temp 38 degrees F All I can figure is because of the cold the primers were not hot enough to completly ignite the powder even with the rifle tilted up so the powder charge was up against the flash hole as the bullet bases were wiped clean before loading. Is there something I could be missing.

	Check your firing pin and make sure that it’s not broken.

	I had that happen recently with some 357 mag loads. Turns out the brass was still wet when I loaded them. I think the primers got wet.

	ASSRA # 11318 I haven’t lost all my marbles yet but there is definitely a hole in the bag somewhere.

	The cases were dry tumbled and the primers have a really good dent in them but I'll check the firing pin tomorrow.

	I had that happen with my Shiloh in .44-77. Seemed to dent the primer sufficiently, but they didn’t go off. I took out the breechblock, slid the cover aside, took out the two-piece firing pin and spring, cleaned and inspected the parts (nothing broken), sprayed WD-40 and ran Q-tips through the firing pin channel. Not a lot of gunk came out, but when I assembled everything again, all the rounds (including the dimpled but unfired primer rounds) fired with no problems. Maybe the “smack” of that big side-hammer isn’t as all-powerful as one might assume.

	The hammer strike is setting off the primers but for some reason the powder is not igniting properly. I'm thinking either the primers weren't hot enough for the cold or somehow the spg contaminated the powder.

	sounds simple enough to try the same thing with real primers made for that type of load. pistol primers in cavernous cases seems silly to me anyhow. first, try to cleanup that firing pin to make sure. good luck and merry Christmas.

	I've been using 3031 in my hunting rifles for decades and I have never had an ignition problem from the cold. It was 9 below zero this year when a healthy dose of 3031 in my 45-70 put a buck on the meat pole.

Same here I use 3031 for my competition loads and was shooting 2 other calibers that day that were loaded with 3031 without any problems. The only difference was they loaded with the old type lube and large rifle primers. .40-65 and .45-70

	I have had misfires with certain types of smokeless powder with colder temperatures. The solution was to use rifle magnum primers - NOT pistol magnum primers.

	I had a batch of .357 Magnum do the same thing a couple years ago. They were all 148 grain DEWC bullets with a light load of Bullseye. I’ve shot that load for decades with no problems. I pulled the bullets from almost 100 rounds, and all had powder, so that ruled out a no powder situation. It was the last box of 100 primers out of an old brick of Winchester SPP. I was shooting indoors, so temperature wasn’t an issue. The same load from the same 8 pound keg of Bullseye worked before that batch and after that batch. To this day I blame it on a bad batch of primers.

	Had a somewhat similar thing happen in one of my silhouette pistols, chambered in 7 mm BR. As I recall, the load was about 25 gr of 748, with a Hornady 154 gr spitzer. The primers were CCI BR4. This load shot great in the summer. Tried it in the winter, temperature around 25 F, and got a number of hang fires and complete misfires. I disassembled some of the misfired loads and found that the primer had detonated, but the only evidence of that was a small clump of powder about the size of BB fused together. I talked to a ballistics tech a Sierra about this, and he recommended using a standard small rifle primer, instead of the BR4, stating that the BR4 primer is very low powered. I tried this, and found that the low temp ignition problem disappeared. Mike

	That's a pretty light load of 3031 in those big cases. Years ago I used a lot of that powder in light 45-70 cast loads. 38.5 to 40gr with a 405gr bullet. Often I would get hang fires. I never use less than 45 gr now and haven't had that problem recur. For light loads I switched to H-4198 and magnum primers which is a great combo. I don't know if that powder is suitable for the 50-70 though. Chris.

	In the 375 H&H with cast using 4895 I had hangfires years ago in the winter.I cant recall the charge but knowing me it was probably a 1600 FPS with the RCBS GC.Iv went to 5744 since then and haven't had a repete.I also use 5744 at 30-35g (no filler or wad) in my 50-90 with great accuracy and no unusual ignition. That load was shared here from another member and it's wonderful.
