bjarup, the Khan has plenty of power for hunting my man.... I am shooting the 55#@29 inch draw just like you and this thing throws arrows!
I'm shooting 500, and 550 grain arrows, total weight, some 600 grain arrows, and the penetration I get is astounding. It is also silent, you can barely hear it, only the arrow whacking the target.
I put some beaver fur silencers on mine, shoot it three finger at a slight cant, and I'm shooting groups out to 15-20 yards with no problems! I'm new to traditional archery and this bow has been very forgiving and a ton of fun. I don't think I will ever shoot another type of traditional bow with a 3 finger draw after having shot this one.
I have shot my friends long bows, and recurves, and they are just too bulky and have unnecessary weight and heft. To me I feel like I'm holding a log with a string after using this.
This bow feels like an extension of your hand, doesn't even weigh a pound, and is very forgiving.
I use the full length 33" carbon arrows I'm using for my other Korean Traditional bows (Gold Tip Traditional 5575), and it shoots where I point it.
I have a cronograph on its way to me, I will post the different speeds and FPE (foot pounds energy) calculation based on weight and speed to see how much power this thing is actually making. This is a phenomenal bow for the money, and is built to last with the micarta limb tips.
I recommend heavier arrows, like 500 grains, to get optimal flight. I tried lighter weight beman 340 carbon arrows, that were 9.3 GPI with 100 grain field points, and they were fishtailing all over the place. The arrows flew noticeably faster, very very fast but they were flying erratically.
Now, haha I don't know if that was my shooting or the light weight arrows, but I'm sure the arrows were more sensitive to proper release at the lighter weight. These heavier arrows I'm using are much more stable and smooth shooting. If you want to use your carbon arrows, I recommend getting 100 grain brass inserts for the front end, with 125 grain points, leave it a few inches longer than the draw and let them fly. Also using 5" feathers on a 120 degree right wing helical is great.
I am experimenting with 4" feathers, 4 fletch with 90 degree placement and right wing helical to see if there is a difference, and will report back. Somehow I feel the 5" feathers X 3 @120 right wing helical is the best combination.
What do you plan on hunting and where are you hunting?
