Hello Don,

You might be right.

Yes, I know, but I additionally wanted to make the point that the impuls is just mass x velocity. And for that reason the higher weight of the bullet might be problematic.

In the end the only way to find out is to try the different ammo.
And I will follow the advice concerning the starting point with 124 or 115gr low power stuff.

Best regards,
