Well with some further testing I am back to the Injexions and feel they are giving me the best overall tightest groups, that's what I am after. I will say I have had 6 now that have had some slight wobble after quite a bit of shooting. After further testing I find it coming from the D6 fieldpoints so I will need to carry some extras all the time. I feel it is do to the reduction in the shank size and might be prone to the weak spot. You probably would not notice it shooting a bag target etc. However, I have been shooting through hay bales with the black mates behind them and they have been penetrating them in a big way. I seem to not have an issue with the standard shanked fieldpoints but the D6 have not held up as well in these same conditions. I will continue to test and monitor this as time goes by.
