I was addressing Ron, since he started the thread, and posted his results. Looks like his Volume equivalents got him the same results out to 200 yards, even though the charges were weighed and quite different from the two different lot numbers. You must have missed this from Ron, right before my post?
"Hey Doug,
Haven't clocked the load from lot 31 yet, but did shoot the loads this morning. Shot 250g XTP. Shot them from a rifle zeroed for 460g conical loads, so had to shoot at 25 yard, then 100 yard.
After hitting the bull at 100 yard; moved the target out to 200 yard. Turned the elevation dial up 7.5 moa, the same as i used to do using the lot 29 load. The bullets hit the bull.
It seems the bullets shot by 61.4g weight of lot 31, fly about the same as bullets shot by 67.4g weight of lot 29. Just one look is all, so far."
I'm always relaxed. It seems the guys that weigh it, are the ones that get uptight and defensive. I quit weighing it way back in 2008, because there was no practical difference at normal hunting ranges out to 200 yards. I could care less about long range hunting and target shooting. They have a forum for that about 5 doors down.
