Ok now we have something to work with.........

If you start at 292fps as What Browning says the IBO speed is I' ll give it a rough guess.

292-(25-30fps) for your draw length at 27" = 265fps.
Now your arrow weighs 200grs over what would be an IBO legal arrow of 250grs.
What this means is that you are probably losing about 80fps.
You are now looking at 265-80= 185fps
Minus some for what you have on the string and the fact that its a 50-60# bow probably means another 10-25fps loss.

until its all said and done your bow is shooting about 170-175fps is my guess...and if that' s the case and your arrow really weighs 458grs you are looking at about 30 ft lbs of KE

If all that is correct this means that you are marginal for hoping to get a pass thru on a whitetail consistently with ANY broadhead.
My advice to you is TRY to shoot a little more draw weight IF YOU CAN. It will help if you can do it comfortably.
Keep the shots VERY close and perfectly broadside.
