Yeah, after I wrote that, I thought it might cause some confusion; didn't really make sense......what I meant it, that yes, they most certainly DO have great powders which reloaders don't have, but I believe that that had already been using it in all of their rounds, to get the best possible vels one can get, within saami pressures, and so what I meant was, the leverevolution ammo is no different in that respect - it is going to be very efficient, but no more so than other ammo from them, including the previous ammo in .30-30, .444, and .45-70. The light mags just push the pressure limits with those same great powders; hence the warning bolt action only. Anyway, good idea, but not a *major* improvement over the old - not enough to convince me to change anything that I use.
As far as the extra vel you mention, I believe that it's not *really* there - it's a combination of flat out exxageration (falsehood), mixed with quoting vels from really long test barrels, mixed with rounding up, mixed with test firing in 95 deg heat, mixed with (you get the picture). But just my opinion.
