Winchester Large Pistol Primer in Rifle?

[BBDartCA]

Bought by mistake a couple boxes of Winchester WLP (Large Pistol). Are these OK to use with 30-06 or 308? Dimensionally they look the same as small rifle. I've heard the only difference in the WLR versus the WLP is the WLP has a thinner case.

I've been told by RC that they are shorter then LR & they look to be but I have never measured. I use Tula LPP in my 30-06Sprg all the time with fast powder. I've been told that they tighten your ES numbers but again I've never tested that ether. I do know it is a quick way of knowing which powder is in the case.

The large pistol primers are both shorter, AND thinner. If seated to the bottom of the primer pocket, they might be too low to get a good hit with the firing pin. But that's the good news. The bad news if you're using them with a normal powder for a normal bullet weight, they'll possibly pierce, the FP dent or fail at the edge of the cup. Both could badly damage the bolt face due to very hot powder gasses escaping the hole.

Get some large rifle primers, keep those pistol primers for if you ever load for hand guns.

Snuffy beat me to it; too short and too thin can be hazardous...
