Shot that well last year and the start of this year too, only when I took it out to double check my zero for the ML season did it change. It was a lot colder the last time too. I found an average 120 gr (volume) comes out to about 88gr wieghed on my scale. Could the cold affect the plastic sabots and not be as plyabe or load pressure. Also I noticed that the new boxes of sabots have a lighter color of blue than the old ones, could this be a problem too? Could my BH209 be getting old? Or could it be how tight I pack the bullet in the barrel? Thanks for any help, Meatyrem
The [new] sabots could definitely be the issue (the age of the BH209 should not, especially if you used the same powder this year), I believe TC switched something in their SuperGlide sabots also. I am now using Hornady's version (same bullet, different sabot) with better results. You could try purchasing Hornady or M&P sabots and see how they shoot.
One other thing I would check is the hinge pin, make sure it is still installed properly and not rubbing on one side of the forend or the other.
Good luck, and let us know.
