Interesting results.
I was watching your video while sitting at my shooting bench and thought what the hell I should give this a try.
.25 cal 380mm Superior liner shooting 25.4gr @ 860fps from my Crown.
My results at 50yds we’re still minute of squirrel but definitely opened up a bit.
Nice comparison. That certainly looks like a significant difference to me. As others have noted, it probably depends on the individual and how accurate that particular shooter and gun can be as to whether this amount of change would cause a miss. I would certainly prefer the first group to the second.
