Hi

I have recently got into reloading the 7.63Mauser pistol cartridge.

As usual the best reloading tool is a chrony.

Fiocchi factory ammo does about 1250fps out of a 5.5" bbl. That's hardly the 1420fps the books and Fiocchi's catalogue talk about. It is much louder than anything else I have shot. I guess this is to make you feel that you are really playing with something hot.

I had some DWM shells in my collection, grabbed the uglyist one and fired it off. It recorded a speed of 1345fps. That's more like it.

7.0 grns of SR4756 with Sierra's 85grn .308SP loaded to a length of 1.375" gives and average speed of 1344FPS +/- 20fps. The stretch marks on the reloaded cases match the fired DWM case. Point of impact is the same as Fiocchi.

You could lighten the load to be kind to your baby if you want, but 7.0 is not harsh.

Don't forget, you can get new recoil springs from wolff. Highly recommended <img border="0" title="" alt="[Wink]" src="wink.gif" />

I have been trying to get a 84.grn cast bullet to shoot in my gun, Trying being the key word, they keyhole so beautifully.

FWIW. I use Lee dies, but I am not overly impressed. If I had to do it all over again, I would get RCBS.

Have fun
