"A 34.6 grain load in 30/06 with the FA 173 grain boat tail was listed at 51,000 CUP in the early 1950's. Our target load in '03's is 16 grains with the 200 grain cast bullet. I have seen two double charges of 32 grains. Luckily both were Remington WW2 actions that bulged the barrel shank's square threads into the receiver requiring machining to remove the barrel. Both case heads failed releasing gas into the action and both blew the magazine floor plates out and cracked the stocks. Both shooters had powder burns and splinters in their right hands. Cone breeched actions are not the ones to be shooting when this happens.
Reduced case volume and a cast bullet in the 308 must be making enough for the primer to blow."
I forgot to mention that the floor plate, follower and spring were blown out onto the bench. Inspection by a member who is a gunsmith and has owned a shop for many years said no apparent damage to the rifle.
I truly appreciate the very detailed responses. I'm a little better informed today. I hope it sticks. Gray hair is working against me. But I do find that if it is a subject I truly enjoy, it tends to stick. When the info is analytical in nature, I don't think you need to remember it, it just folds in with the info already stored in the gray matter.
I've loaded 30 rounds with those PC bullets. I weighed them and they are a nominal 167gr.. They are bevel based, so that might work against them for accuracy. Although the BB bullets I got recently with a .38-55 Browning Traditional Hunter have shot well in their first trip to the range. Will be taking that rifle with me as well. It now has a set of Steve Earle's blocks and my 10X Lyman STS will be on it. Excuse list just got a bit shorter.
