....finally got out over the weekend to try some accubonds and was pleasantly surprised to see the same results as many of you have expierenced /ubbthreads/images/graemlins/smirk.gif.
Gun is a 300wm Rem700 Sendero w/a 25" barrel. Leupy 6.5X20LR. nothin fancy, had the action/lugs lapped and brake installed a while back nothing else....oh, i skim bedded it a month ago...
I shot six different groups at 100yds. Three with IMR 4831,70gr,71gr,72gr, and three with R-22,69gr,70gr,71gr. The best results being with 72gr of IMR (.545 three shots) and 71gr R-22 (.520three shots). The R-22 group was a perfect vertical string (barrel heating i guess) and the IMR was purty little cloverleaf /ubbthreads/images/graemlins/grin.gif. didnt have a chrony for the fps but pressure signs are minimal(minor primer flattening/no cratering/no ejector marks)
...even out shot the guy next to me w/a 6mmBR... /ubbthreads/images/graemlins/wink.gif /ubbthreads/images/graemlins/grin.gifanyways...
heres my question for some of you...what load do i go with to hunt deer this october?
i have heard about R-22's sensitivity to temp but exactly how bad is it?? what about the IMR 4831 is it temp sensitive too.
I have loaded up ten of each of these two loads to run across a chrony this weekend to see which is the most consistent, but i would like to ear more about each of these powders and which is more temp stable... preferrably from expierenc, not what the mfr says /ubbthreads/images/graemlins/crazy.gif
Thanks in advance for the input...
