Having just about run out of Varget I'm looking for an alternative european powder to use with Speer 85 gr BTSP and Sierra 85 gr BTHP bullets in my .243. Viht list N150, N540, N550 and N160 as the powders for 85 grain bullets in their latest .243 loading tables. Speer have N560 listed in their tables and Sierra N140.
I've tried N140 and at Sierra's max load (37.3 gr) get good accuracy but modest velocity, barely 3,000 fps through my 22" barrel which is marginaly large deer legal in England. Has any one experience of any of the other Viht powders listed above with 85 grain bullets? I'm looking for a load which will give accuracy at 3,150 - 3,200 fps which is where I am with my Varget load.
