Maybe that's not the correct term or phrase for what I'm speaking of but basically what I'm talking about is when the gases from the powder charge pass by the bullet/sabot before it exits the barrel. How can I test this without a chronograph?
Reason for ask my is because at the range this past weekend I was dialed my in my omega, my go to load has been a 250 grain xtp with a black crush rib sabot pushed by 90grains of bh209. This load does very well in my gun and I get 1.5" groups @ 100 yards if I do my part. It loads evenly down the barrel and seems to be a snug enough fit. Now while at the range i tried the Federal bor lock bullet 270 grain trophy copper. It consistently shot 4 inches higher tHan my xtp does , I found it strange that a slightly heavier bullet would shoot that much higher which leads me to think I'm. It getting a good deal with the xtp and crush rib sabot, even tho it's very accurate. It worries me that I may be losing velocity, any thoughts on how to test this? Or am I being a worry wart?
