The 50 gr with a relatively light 200 gr bulltet is more than capable of taking deer within the 100 yard range with very mild recoil. Where we hunt you will not get many cahnces at a deer over that distance anyway. All deer I have taken as been 35 yards and under.
Take a look at the Photo Corner - 2009 Harvest Photos or go to the Indiana forum. Got pics of my son who took a doe Saturday morning with the CVA Wolf using the exact load I stated. The shot was at 10 -15 yards but the bullet went clean through the deer. I have taught my son to always shoot center mass and put it in the boiler room rather than go explicitly for the shoulder. Deer ran maybe 40 yards before dropping, babout what you would expect from a similar placed bow shot.
Hope this helps. If anything just try various bullets and powders. Just cause mine likes the combo does not mean yours will.
Veni, Vidi, Sagittam Mittere, now I'm ready for my nap
