Besides blown primers a problem with misfires may occur due to .008" shorter pistol primer not getting a suffecient primer strike...

Yeah, I considered that but my test shots (primed cases - no powder) in a Yugo M48 and an SR 96/11 went BANG without a twitch. I haven't actually measured but it appears those old milsurps have a bit more firing pin protrusion than something like my Savage M10 or M700s. Loaded up twenty each 8x57s and 7.5 Swiss with 700X and W-W LPs using load data from Lyman Cast Bullets #1 and will post result after my next trip to the range.

Never had a problem using Win LP primers with cast bullet loads......257 Roberts, 260 Remington, 7mm08, 308, 30-06. 30-40 and 7.5 Swiss
Got to the range this morning and test results were actually a little better than I expected. In both rifles, POI @ 100 yds was about 2 1/2"-3" lower than my 'regular' loads (LRPs and 4895) but, maybe, just a skosh tighter (or I could have just been having a good 'iron sight' day :wink:). Anyway, all 40 rounds fired consistently with no flyers that might indicate erratic ignition. Also fired a half-dozen 30-30s, using essentially the same load, through a 10" Contendera - same story: clean ignition, decent grouping, no flyers.
All three loads look promising and worth fine-tuning.
