7n1 ammo question

[pslshooter]

I'm pulling the 7n1 bullets from the ammo I have to reload into boxer primed cases and I am wondering if I should save the russian powder to re-use. I would like to know what common commercial powder it is equivilant of similar to.
The reason I'm pulling the loads is that the 7n1 is too long to operate consistantly thru my PSL mags. I know I could just re-seat the bullets to the length of the CZ rounds that operate without fail, but I'm going my own way and putting them in new cases.
Thanks for all the help, any info is greatly appreciated.

Just a suggestion. Pull the powder from 10 rounds and check the charge weight spread. Get a good average and write it down. Check the capacity of your boxer primed cases versus the 7N1 cases. You may or may not find a difference between the two. If your boxer primed cases have less capacity than the steel 7N1 cases you may have to reduce the powder charge to prevent getting overpressure. Not familiar with either the 7N1 cartridge or the PSL but since its a gas operated firearm playing safe with the brass cases may save you some aggravation and spare you from messing up the case rims. Sort of like the port pressure on a M! Garand. Frank

The average load of the russian powder is 46.5 grn. The case capacity is slightly higher in the brass vs. steel (.5 grn). I've loaded up 25 rounds witn this spec and the length from The CZ LPS ammo for consistant feed thru the mags. I'm hoping the brass will hold up to this mixture. I've ran some 150 grn loads in brass thru it and have had no case problems except finding them after fired.
The PSL is basically an beefed up Ak action to handle the  x 54r ammo. Used effectively as a Designated Marksman Rifle by the Romanian Army. I've had a lot of hands on training time with the Romanian military rifles during my deployment.
The 7n1 round was developed for the Dragunov SVD. A specialized round for their snipers, very high ballistic coeficient for long range shooting.

Thanks, I have looked at the specs for the 7n1 b4 I even considered doing this. By pulling the rounds I did find that none of them were over 47 grns of powder let alone 47.5. I zeroed and recalibrated the scale several times to verify my findings. All of the bullets were consistantly 151grns with only minute variations (.01 - .08) and those being small specs of powder in the hollow bases of the bullets.
