Please don't use my load figures, these were worked up carefully using special plastic bullets and are not suitable for normal bullets.
I'm trying to work up some max loads for 55gr remington SP bullets loaded into 5gr sabot sleeves in the 7.62X25 out of a CZ52.
With the factory powder (from recent production S&B 85gr ammo) I had to increase the charge about 30% (working up carefully) to get the pistol to cycle and that is still a low pressure load with no signs of pressure on the fired primer.
Using alliant unique the pistol barely cycled with about 20% over book (for a normal 85gr bullet) and 30% over it cycled OK but that is the casing full to the rim. Both of these loads are fairly low pressure but physically too much powder and make seating difficult so I need to find a faster or lower volume powder to work up some full pressure loads.
I'm thinking I'll buy some accurate #5 and try that but I'm open to other suggestions. I have bullseye and tightgroup on hand but my manuals don't list any of the fast powders for this round so I'm shooting in the dark with those.
If anyone has sabot data for 7.62X25 or .30 carbine it would great.
