I was fire 240 gr xtp with mag express sabots under 85 grs of paradex p at 100yrds. my shot where all over the place some did not even hit the target. I was shooting nice groups last week with the same bullet/powder combo but it was in the mid 70's overcast and slite breeze but today almost 30 degrees cooler clear and little to no wind.
Corey, just my thoughts so do not necessarily jump on them, usually for me ML's do shoot better when it is cooler outside, especially when shooting sabots. The one thing that kinda sticks out gor me is the powder charge that you are using. Again for me only, I have not had the best of luck shooting light charges with the lighter bullets. I guess I would suggest bumping up your charge to at least 90 grains of Pyro and probably 100 would actually give you better accuracy + velocity. I am shooting T7-2f so my velocities will be a little different than yours if you are shooting a Pyro powder. I normally shoot 100 gtains of T7 from my inlines and 80 grains from a sidelock true Renegade.
For me, the added pressure/velocity of the greater charge creates a better gas seal with the sabot/projectile combination. and still of course the biggest effect on accuracy is the condition of the bore...
