Thread: 7.62x39 reloading.

I have a CZ carbine that I use (Lapua brass) a 123 grain Hornady SST on top of 28 grains Reloader 7. Primers are Federal 210M. This is one grain over Nick Harvey's max but no pressure signs at all. I seat the projectiles quite long - a lot longer than you would have in a semi.

Please work up at least 3 grains below that.

Nice, Thanks @huntsika for that one. Any idea of the velocity? It looks like Serious Scooters has Reloader 7 by the pound! Gets some good velocity in 22 inch barrels by the look of the data. Has anyone tried Vihtavuori N120? Oops, mistake in my first post, it is from Serious Shooters. Great velocity claim from a short 16 inch barrel, nearly 2500fps.

A little over 2400 - was chronographed but a long time ago and I think that might have only been 27 grains and not 28 (?). I've only got a 16" barrel so pretty good in my view - I also briefly tried AR2207 and one of the Benchmark Powders (either I or II), but found Reloader 7 really well balanced in terms of pressure and accuracy so very quickly gave up on anything else.
