Re: powder/load recommendation 338lm/berger 250otm
Lag time might be the same, but trajectory WAY flatter. Ballistics tell me nearly 2mil difference at 1k. Less drop means flatter trajectory and less vertical spread for variances in velocity. In fact, according to Shooter, the 250s have slightly less wind drift at 1k. So at shorter distances the 250s have the advantage IMO.
What other powders do you recommend? If I knew the MV/°f for a given powder without having to send a hundred rounds down range I'd have less problem with non extreme powders.
