Thanks for that...I'm not after super high velocity but would like an accurate load that gives me 2900fps, but I don't think is unreasonable.

Upto now, the loads I have tried with Varget and RL-15 show good accuracy at 2650fps -2700fps, but then fall off as the velocity increases.

I have a batch of 155grns loaded over some TAC to try next, and if that doesn't work I may switch to VV N140 or N150...

Acutally their N5XX powders sound like they are meant to perform with similar pressure curves to Rl-17, so N540 or N550 maybe worth a try as well..

Regards,

Peter
