As a follow up, 168g tsx shot as follows today:

89g 7828 = .5"
87g MRP = .8"

180g nosler partitions:
85g 7828 = 1.25"
84g 7828 = 1.0"
82g MRP = .8"

165g Interbods were a dissapointment--they seem to pattern more than group:

86g 7828 = 1.25"
87g 7828 = 2.25"
88g 7828 =3+"
86g MRP =1.8"
87g MRP = 2+"
85g MRP = 1.75"

150g Lazzerheards (a variation of the tsx marketed by Lazzeroni--it's manufactured undersized then a superslick finish is electroplated on it bringing it back up to diameter)

90g 7828 = 1.0"
89g MRP = 1.25"

This same rifle shot 2" to 4'' groups with the same bullets using various charges of RL22

I'm going to play around with the tsx and lazzerhead seating depths to see if I can improve these any. After 6 different boxes of barnes bullets (XLC and X), I've finally found a bullet with acceptable accuracy--I'm thinking the 168g tsx will be just about perfect for a long range deer load/back up rifle load for elk .
