[QUOTE="johnnyk, post: 75789, member: 307"] cbaker, I have more or less given up on the (non)AccuBond in my .25-06 Sendero. I tried IMR4350/w CCI BR2's. Started at 48.0gr and increased up to 49.5gr in .5 gr increments. Velocity average (3-shots) was 3009/3021/3029/3115fps. Accuracy was .4345/.4870/.6555/.7490". Then I tried IMR4831/w BR2's. 51.0-52.5gr, velocity was 3143/3136/3175/3214fps and accuracy ran 1.041/.7205/.8595/1.327". Next was RL22/w R9.5M. Loads were 53.0-54.5gr. Velocity averaged 3181/3218/3242/3271fps. Accuracy ran .8435/.7570/1.1365/.6690". Three days later I tried 54.5 & 55.0grs and believe it or not velocity average and accuracy for the 54.5gr load was almost identical. Velocity was 3271fps (exact same as before) and accuracy was .6965"! Only .004" over the previous group. Velocity and accuracy for the 55.0gr load was 3302fps and 1.0705". This is about where I wanted the velocity to be (3300fps) but I was hoping for better accuracy. I may try them again someday, but for now will stick with the Barnes TSX's. They are one-holers in this rifle at 3300+fps. Good luck. Johnny K. [/QUOTE]
