What kind or speeds are you guys seeing from you dom. 3d and what setup. Trying to evaluate mine somewhat she's kind of a turd.

27" 61# 376gr xcutter 266fps. I know draw is short pounds are low and arrow is heavy but was hoping for a bit more.

With your dl you'll hypothetically lse 30-36 fps off of your speed. Your draw weight would lose 2 fps at an ibo arrow. Then you're shooting a heavy arrow. With the weight on your string as well you lose more speed and depending on fetching and degree offset they have you'll lose more. I would say 266 is pretty close to what I would expect...

If you went to a 310 gr arrow, you might get close to 300, but I doubt you'd break 300 with a 27" DL.

I was getting 307 with a 311 grain arrow off my old supra me set a 29" so 266 for your specs doesnt sound too bad. You could shoot a 280 or so grain arrow and probably be ok with that short of a draw length. That might get you to 310 or so. I wouldnt as I found the light arrows made my bow feel harsh on the shot. It still shot fine and was indeed faster. The trade off was not worth it to me since feel is a big part of being comfortable with the bow.

Shoot, work, shoot!

I wouldn't shoot a 280 grain arrow pulling 61 pounds no matter the dl. I wouldn't want to go below the 5 grain per pound rule period.

The 5 grains per pound thing is debateable. I believe that applies to a 30 inch draw and we know a 30 inch draw will produce much more speed or force on the arrow if you prefer than a 27 inch draw. 280 gr. @ 27" wouldnt do anything worse than 305gr. @ 30". I personally dont like the extra vibration and jumpiness ina bow thats shooting a super light arrow, but I dont think it would damage anything. Now if I were the OP I would be looking for 280-290fps. That seems to be the best balance in speed versus feel for me. To achieve that speed he would only need to cut about 50 grains of fat. He would still be safe with 5gpp at 325 grains or so.

I could see how it's debatable but I wouldn't want to chance it. However I agree that I wouldn't want to shoot a super light arrow due to the effects it has on the bow such as noise, etc. I also agree about the 280-290 fps as well. That would be excellent speeds for that bow with that draw length. I would try to cut some weight off of your current arrows and attempt to get 280-290. Just my opinion, I've heard of people going below 5gpp but I wouldn't personally.

Ran the setup through the calculator at a 325ibo and got 266fps so it is what it is. I dont need the speed for indoor and indoor 3d right now. The thing drives tacks so i cant complain about that.
I will probably got to my 320gr GT 22's for k45 in the spring. thanks for the input guys.

Shooting known distance I would NOT give up even a .1" of group size for 20 fps! I shot K45 this past summer at 277 fps using a 26" draw on a Supra ME with no complaints.
