Quickdtoo-
I was pushing them with 100 gr of T7 (two pellets - actually, a bit less than 100 gr I believe). Got lots of flyers. I tried the TC sabots with the same load and viola, my groups tightened. I also noticed that the sabots fit much tighter in the barrel - perhaps this had something to do with it - who knows? Last year, a guy in a range stall next to me was having the same problem with PB's and I offered him up one of my bullets - he hit the paper for the first time that day. Last Saturday at the range another fellow noted that I was using the TC sabots and said he had switched to them as well after having terrible luck with PB's. Clearly, they work very well for many of you guys, I wish the did for me as well.
I've learn a great deal over the last year, hunting, reading, at the range, and, here on this forum and am now working with loose powder (T7 still). Perhaps I'll give the PB's another try with a lighter load as you suggest. Currently I'm using about 90 gr with good accuracy.
