Easton FMJ question...

[shag08]

Ok. The threads on the new Autumn Orange FMJ's got to me. I love the look of them so I had to have some. I placed an order with 3Rivers and the shafts should get here tomorrow.

 I have been shooting 2213's, which, as I understand it, are .460 spine...30", standard insert, 200gr head. So I went with the .470 spine FMJ.

Now I'm reading lots of recommendations to others calling for way stiffer spines. So what gives? Are the deflections different somehow?

Bigfoot Sasquatch SS 50#@27" drawn close to 28, wanting to shoot 200gr heads. What do y'all think I need? Could use some info from those who are familiar with the FMJ.

I shoot the old FMJ's and I have both .500 and .400 spines tuned. I shoot 49# at my 29" DL. I hunt mostly with the .400 spines because they are heavier with a higher FOC.

You should be able to get those .470 spined shafts to work, but you will have to play with length and insert wirght to get them just right.

Thanks, Bisch! In all honesty, do you think I would be better off to send them back and exchange for the stiffer spine? I'd rather have a longer shaft with more weight up front than a short one with less.

I just noticed "50@27, drawn closer to 28". That means your actual draw weight should be 52-53#. Can't really tell you for sure over the Internet because everyone is different and does things differently.  If it was me, I would go closer to .400 spine, but I've got all that figured out for me.

I hope that makes any sense at all!!!!

Thanks again, Bisch. They arrived today just as expected...gotta love 3Rivers! They look even better in person than I expected. I think I'm just gonna throw caution to the wind and cut one to about 29" and see how it bare shafts. If it doesn't work with the bow I want it to, I've got others in the mid 40's that maybe it'll work with. Or there may be 11 autumn orange shafts in the classifieds soon lol...I hope it doesn't come to that.

Thanks again for your time and advise.

Suspicions confirmed...at least with the Sasquatch. I cut one all the way back to 28.5"....apparently I've changed my form since I last checked draw length, I'm right at 28". And the 470 is weak with 200gr heads. I got the truest flight with 125gr. I want more weight than that up front though.

Tried the same shaft through a Bear dog leg Grizzly, 50@28, and a Bob Lee Hunter hybrid, 49@28". It was too stiff cut to 28.5" with a 200gr head. I'm sure they will work just fine full length though. But I didn't try them out yet.

Lesson learned here. And if anybody is shooting low to mid 50's, go with the stiffer spine in the FMJ's.

I have shot FMJ for many years and have found that a lot of weight up front is not needed to get great penetration.
