I just switched from a Mathews Legacy at 64 lbs of pull to a Mathews Switchback that is currently at 67 lbs of pull...but I plan on moving it up to 70 lbs. I sighted it in with my Beman 400s, and then had my bowshop cut me a dozen more arrows.

While I was waiting for my arrows, I read the Beman arrow chart...and it indicated that I should shoot 340s...not 400s. The guy at the bowshop said that there was such a nominal difference in the two, he thought I'd be fine with the 400s.

What do you think?? Does it really not matter all that much..?

Thanks!

I think the guy at your bow shop needs an education. There is a very definite difference between 340's and 400's. You don't say what your arrow length is but, unless they're REALLY short, I seriously doubt those 400s will handle 70 pounds of draw weight.

I second arthur P. And, if you are shooting with a release and even stiffer spine usually works quite well. I'm shooting 27.5 inch Gold Tip XT cammo hunters with my 70# bow and my arrows are spined at 75-90. They shoot like lazers for me. I've had my best experience when using stiffer spined arrows.

If youre arrows are over 28" and using heavier than 100 grain head yes there is a big difference!
If you are 28" or shorter and using 100 Gn or less Heads you should be OK
However I HIGHLY reccomend a stiffer spined arrow!

Arthur P remember every one isnt Nuckle dragger like you JK

OK, you guys have me worried.....I shoot 68 pounds, 29 inch arrows, and I also shoot 400's. I saw the same chart and will be switching after season is over in a week, but I have been shooting the 400's great. They shoot very well for me, but I will be curious to see how much better, if any, the 340's do.

that guy behind the counter really doesn't have a clue.

mobowhuntr, I would suggest that before you make any knid of changes at all that you shoot you 400's with broadheads and see how they fly. It might get a bit ugly, but at least you'll know for yourself. And with no more expenditures. And whos ays that you HAVE to shoot all that weight. You may find, by turning the bow down a turn, that your arrow just might work. In that case why spend more money. I don't think any north american game, whether it be flesh or rubber, will know the difference between 70 and 67 lbs.

But I am with the other guys in thinking that the 400's just aren't stiff enough for such a setup.

I had the same thing happen to me years ago and didn't notice a problem until I went to shoot broadheads. Then again, I didn't realise it was an arrow problem until after many frustrating tuning attempts and replacing arrow rest, so on and so forth. I would expect something like this from WalMart or even Dick's, but not a pro shop. [&:]
