I have herd a lot of talk about the MR7 being slow. I have one on order and would like to think it will shoot its ibo speed. However everyone i have talked to says it wont shoot what its advertised too.
Any thoughts on this. What do all of you know.
My PSE Dom pro at 29 70lb shoots a 390gr arrow at 296 I would like to think the MR7 would be faster but eveyone says dont get your hopes up.
Joined: 1/3/2012I have a MR7 29.9/70
I have shot it with a 350g arrow and it chrono at 332 fps with peep and D-loop on string.
My hunting arrows are 395g and and it shoots at 321 fps.Good to hear.
And is that supossed to say 29.9 or 29.5 just waned to be sure on waht your DL was set at.
Joined: 1/3/2012yes it is 29.5″ DL sorry for the type O
Joined: 12/21/2010Make sure you carry a bar of soap with you. It will help the arrows pull out easier.
Location: MnMy M7 is 28.5@60#. My hunting arrows finish out at 400gr. and it chronos at 288 fps. You shouldn’t have any problems hitting IBO with it.
SCFoxStone tactical has arrived!Anyone else have any thoughts?Should I be worried? Only two people have anything to say? O man o man

I will guareentee that if the bow is spec tuned it will meet or exceed advertised IBO…
Take rated IBO…
IBO speeds are based on a bow with a 30″ draw set at 70lbs shooting a 350gr arrow.
-For every inch of draw length you go down you will lose 10 FPS
-For every 5# draw weight you go down you will lose 10 FPS
-For every 3 grains of weight your arrow is over IBO ( 5 grains per pound) you will lose 1 FPS
-For every 3 grains of weight you add to your string you will lose 1 FPS
I’ve ran mine at 28″ and 70# on several occasions and with my 490 gr. arrows and just a d-loop and peep I’m at 280fps.LOST
With all that being thought out befor I was looking for 305fps I get IBO out of everything I have ever tuned. I have just been told by a few people locally it won’t do it. I told them your crazy I said if it won’t IBO it has problems! I appreciate your response and I am confident it will. I also like hearing what others rigs are getting.Got the 7 in and with a 28.5 in mod at 71lb with a 390gr arrow it’s at 311!!!!I am currently thinking of buying a MR7 I have a 31.5 inch draw and was wondering what types of speed I would be looking at with a 60# versus a 70# bow. I currently shoot the Switchback LD 32″ draw 71#. I was never into the “Speed” thing but from the looks of things this would be a considerable upgrade in that department.
