Throat length, does it really matter that much?

[QUOTE="KYpatriot, post: 1003111, member: 48028"] Is there enough barrel to get complete burn of the extra 3 gr of powder? I assume 30in would be enough, but if not perhaps the extra 3 gr was wasted and that's why you only saw an additional 4 fps. It would great to do your test with the pressure trace system. I have thought about buying one myself just out of curiosity. I wonder sometimes if we might be surprised by what we think we know about chamber pressure by reading brass. So far spending $600 of the gun budget to buy a strain gauge out of mere curiosity seems a little much for me since I am not pushing the boundaries of the sport or creating new high performance rounds like some of y'all are. It would be really cool though to correlate reliable chamber pressure data from a strain gauge with our observations of brass condition ( and velocity data) to see where the truth lies in reading brass. Any ever used that pressure trace system? [/QUOTE]
