It was 75 degree and beautiful this am. I shot 20 shots in all, all at 100 yards (really 92.5 range finder yards):
5 TC Bonded SW, 300g
5 Parker Ballistic Extreme, 275g
5 Barnes TMZ, 290g
5 TC SW, unbonded
all using the supplied sabot, all shot with 44g of Accurate Arms 5744, and using Remington Kleenbore Primers.

Here is the TC Bonded SW, which I shot first.





Then I cooled the barrel with towel soaked in ice cubes and shot the Parker Ballistic extreme:





I then cooled the barrel again and shot the Barnes TMZ, 290g:






The best overall group was the Parker Ballistic Extreme, with about a 1.5" or1.75"group, I was supprised at the spread of the TC SW, both bonded and unbonded. The TMZ has not performed well in the rifle, most say you have to push it faster, which I will try. Right now, my fall load is going to be 44g of AA 5744 and a Parker Ballistic Extreme with a Remington primer.
