View Full Version : 60lb(max) bow vs 70lb(max) bow FPS comparison

I have what may be condsidered a dumb question but, being a beginner, it's worth the humiliation it might bring with it. Does a bow that has a max of 60lb pull shoot at the same speed of an identical bow that has a max of 70lb pull with both set at 60lbs - or - Since it is designed for a lower max would you be forcing the arrow faster do to it being at the max range of the bow?

Will a bow will shoot the fastest at its peak weight? It can because at its peak weight the brace height is at its lowest, and power stroke at its longest. Does it always? No. Can I prove that? No, unless someone would like to sent me two warthogs @ 60# and 70# so I can get some data. :D

Personally, if I want say a 60# bow, I would still order a 65# or 70# and wind it back a few turns. Always good to go heavier if needed (or my shoulder tolerates it) and the limbs might last a bit longer. Will it shoot faster that way? Possible from what I have seen.

Btw, not a 'dumb' topic at all. Quite interesting really. :)

There are many that say a compound bow will shoot better at it's maximum weight, that is with it's limbs wound down to the max.

In my experience, i've found this to be not true. I purchase bows that have 70# limbs, but shoot at around 65#. Importantly, when I tune them, I tune them at 65# not at 70#. I know there are also many that say tuning should be done with the bow at it's max, but having tried both ways, I find that tuning at the weight you are going to shoot your bow, produces the best results.

I know this is not answering your question exactly as you asked, but seeing as our mate Destroyer has already done that, I thought I might pass on a bit of info that might help you. And never think any question is dumb, we were all beginners once, so ask anything you want, there's plenty of good people here a lot smarter than me!

There is an test on 'Budget Bows' in an older Bowhunting World mag showing the difference. Some are faster @ 70# down to 60# but some were not. I'll have to dig it up.

An article or test report would be a good read. I appreciate the help so far. I have an issue with my shoulder and I truly believe 60 will be the max I will pull after rehab. Currently pulling around 53lbs and working up on the 60lb max bow but my wife is wanting to buy me another bow. How can I argue with that?

You cant argue and you shouldn't! Listen to your wife and get a new bow, NOW!!! :D

08-05-2010, 05:04 AM
I'm with Greg on this one. Don't argue and let the wife buy you a new bow.:)

Glad you guys are behind me. :)
Any suggestions on which bow? (I have a somewhat low budget to work with)

08-05-2010, 05:55 AM
Since you are on the Martin forum I will assume you are looking for a Martin bow. The Firecat TR1 or the Pantera would be my choice or you could look at the Bengal. All are nice bows and priced reasonably. Shoot as may as you can and pick the one that fits you the best. If you have to save a little longer to get the right bow then do so, don't settle for one that doesn't feel right to you. JMO. Good luck.

That depends on your draw length and if you want single or dual cams.

08-05-2010, 06:57 AM
Martin is fine with me. I'm not the picky type.
27" Draw. Single cam please.

08-05-2010, 07:02 AM
In this case:
FireCat TR1 as a Pro Series bow

Pantera or bengal as a Gold Series.

Thanks. I have heard a few Bengal lovers rave so I might lean toward it.

Regarding if you should buy a 60 or 70 lb max bow. I think you need to look at what type of shooting you will be doing? Will you be hunting? Do you have or will you be getting a range finder? I personally am not very strong and I bought a 60 pound max bow.

I have it set around 55 pounds draw and find it a pleasure to shot. If I turn the poundage up, I cannot shot very accurately. I also hunt whitetails in very forested areas and do not have a range finder and I can only estimate distance out to about 25 yards accurately. So I don't anticipate long shots and do not think the lower weight hurts me at all, matter of fact I know it helps me.

Now if I was going to go hunt Elk or bear and needed the KE than I would look at shooting heavier. Or if I had a range finder and was hunting spots where I could shoot long range (above 40 yards) I might look at a heavier draw weight bow to just help out a bit. But really if you look at trajectory tables for an arrow traveling 260 fps versus 280 fps you have to ask if drawing the extra weight is worth it. Do some research, shoot some bows, it is a personal opinion.

Good luck,

Many good points Chris. I will be hunting for whitetail in WV and some target shooting so long range shots will not present themselves as they would out west. I too have doubts on long shots since I do not have a range finder. But, I just worked a deal with my boss to let me shoot on weekends here at work which will give me practice up to 38 yards so that will be the farthest I will send an arrow once I get more pratice in. Right now I only have one pin sighted in at 20 yards and am hitting a 3" cirlce 4 out of 5 times with the 5th being only so slightly out of the circle.

Currently pulling around 53lbs and working up on the 60lb max bow

This is the most important factor. If you think 60# will be the max you will be able to shoot then get a 60# bow. Wind it down to what you are using now. 65# or 70# down to 53# is a bit much. With 60# you have plenty of speed for any animal out to 38 yards and further. Just remember what traditional hunters use. ;)

Which bow? My rule is let the budget decide. Will you buy new everything? What about the Cheetah? Looks good.

In the end I would rather be able to shoot a bow than worry about speed or what the # rating is. You could always get new limbs down the track if you need to go heavier.

On the 60lb bow set at 60, vs 70lb bow set at 60, something I have found on my bows in past years, is that most have generally shot quieter at or near peak weight than they did at the lower end of the draw weight range.

As for the FPS comparison in question, I have shot a couple older Firecats one 80lb max at 69lbs and one 70lb max at 69lbs. Using same arrow, the 70 set at 69 did shoot a couple fps faster, but you might find that difference between two matching bow set the same.
I ended buying the 70lb (still have it and still set at 69lbs) because it felt better shotting and seemed quieter.

FYI: On budget single cam bows, I've really been happy with the Bengal I bought last fall.

RLW, Thank you for that answer. After all the great info from the others you capped it by hitting the nail on the head. Funny you would add your feelings on your Bengal since that is one of the two I am currently obsessing over. The other would be the Bear Charge or Strike.

08-10-2010, 04:57 PM
The only thing I don't like about the Bear is needing a bow press. :)

08-11-2010, 04:38 AM
So I guess that is one more vote for the Bengal.?.

08-11-2010, 09:38 PM
Could be. :D

I'd have a Bengal, nice looking bow. What about colors? Black riser with camo limbs would be my choice. Or maybe the carbon look? :)

08-12-2010, 05:24 AM
I do like the looks of black on a bow. Mixing it with camo limbs is an option. I will have to consider that I will be hunting from a tree, a blind, and from open ground when chosing. You have given me more to think about.

08-12-2010, 05:37 AM
You have given me more to think about.

Hope that's a good thing mate. ;)

It is a good thing. It's nice to have options in life.
