Thanks Cinders. That was on my to-do list. Maybe that rifle just needs slightly shorter boolits...

[CINDERS]

Wow that is a long pill Ovidio that 160 grainer I would be real careful not to get into compressed loads with it

[Ovidio]

That is the reason why I want to try them in very solid rifles.

[Ovidio]

But you got me a bit scared, damn...

[CINDERS]

Its all good Ovidio your not an inexperienced reloader so know the form.

[Ovidio]

Yep. I‘ll measure the oal again and decide what to do.
Worst case scenario, I‘ll cut the loads a bit and see.
The difference in length is not a small thing...
But I‘ll test in very very sturdy rifles. Someday...;-D

Gentlemen, this is an exercise in logic.
The GP 11 came from the same munitions house in 1898 as the new run GP11 ammunition is being made and currently distributed among shooting clubs in Canada and in Switzerland.
The only change that was ever made and that cartridge was in the early 70s when they changed the coagulent.

The seat depth for the GP 11 cartridge is set approximately two thousands off the lands. When you consider that it worked in the G 11, the Kadet, The K 11, the K 31, the ZFK 55, the PE57 and the MG 51 machine gun, (the only one left in the Swiss Army using this round) why would there be any question whatsoever about powder and seat depth unless you are reloading.

If you are reloading and are unsure about any of these factors, please go here

FAQ | Swissproductsusa and read "What is the process for reloading the 7.5 x 55 cartridge?" This is a specific reloading process dedicated to our cartridge only.

As for brass fired from the PE57, Resizing twice might be okay but as soon as you move on to 3rd time you are rolling the dice. Those striations that you see in the fired brass are the areas that have sunken into the chamber striations that allow the rifle to function on a delayed blowback. They are a substantially weakened area, and please take my word for it. After many hundreds of rounds downrange through a number of different PE 57's In the past 50 years, Second and third round full length brass sizing's left us with plenty of ruptured longitudunal separarions along the striations. You might get away with it once or twice, but it will catch up with you if you're not careful.

How are your hands, Pierre? Doing ok?

Thanks for asking. I lost my ability to type so I switched to one of these new Dragon speech to writing programs and it seems to work pretty well. I just have to be careful how I enunciate things. Ma isn't so sure it was a good thing since he says I don't tend to shut up anymore ! LOL
one thing it has allowed me to do is to begin transferring all of my archives from the old Swiss rifles.com website to our new Swiss products USA website. I'm trying to get everything I've ever written collected in one spot before I'm unable to speak. LOL... But again, Ma doesn't think that would be a bad thing. LOL

Tough gal Ma, isn’t she?
