I acquired a good sized batch of once fired PPU brass in 30-06. I normally use Remington and Winchester brass for my 168 match target loads.
I have fired hundreds of these with great results and no pressure signs other than very slight primer flattening. This load(H414) is already under max by about 1.5 grains.
The first time I loaded some of the PPU, I used the same data I used for my target load using Remington brass. It gave some over pressure signs in the PPU brass. Flattened primers and some cases were hard to extract. One primer opened at the edge a little.
I only fired four rounds. I pulled the remainder.
Today, I loaded some of the PPU with a different powder(IMR4895) and went 2 grains under the start load for that powder/bullet/cartridge combination.
These shot very accurately, extracted easily, and had slight flattening of the primers. I didn't have my chrono with me so couldn't test the speed.
Given the slight flattening, this still indicates that the pressures are running higher in this brass than the same load would in my regular brass.
Anyone here have any experience showing PPU brass tends to run higher pressures than other brass?
