Beman MFX 400s

[huntin_sparty]

Anyone who shoots these are you able to use 4 fletch or is the diameter too small?  Sorry Should have used search first.  Please look below at my spine question.
Thanks

You can 4 fletch a Beman in either configuration (90x90 or 75x105) no problem...proceed as usual.

sorry I should have hit search feature.  How about a second question.  On other threads people are using the 500 and 600 spine on 50# bows.  Stu's calculator said I would need the 400 with my various 48 to 53# bows.  29 inches long 180 grain tip 75 grain insert and 4 fletch with a reflective wrap has the rating around 56 and the bows are right in that ball park.  What spine do you all use and what bows.  I shoot a Big Jim Buffalo and Thunder child in the low 50# range and Bear A mag takedown from 45# to 55#s.

You are going to be good with the 400s.  Start full length and shorten till you are close with a bare shaft.

I'm shooting 400's w/75gr insert and a 200g point out of my 54# @ 26in Lil Hoots recurve.

Nice bright arrows!  How long are you keeping them?
Thanks Steve O, also I was real happy with that Sitka purchase we talked about last year, hope you were happy with yours as well.

I cut my 400's to 27 1/2".  I followed Stu cal (Form factor -3 & a SBD 8 strand) and bare shafted them.  They fly perfect.  They also fly great out of my BW.  Arrow weight around 588g w/ insert & point.

Ive been shooting MFX 500's with 145g point and 75g insert out of my Thunderchild with good results.

thanks
what are you all using for field points heavier tan 145gn with the right diameter?

3 Rivers has them up to 200 grains I believe.

I hunt at 46-53.5 pounds. I've used 600 and 500 (my draw is only 26") by simply varying point and insert weights (414 - 507 grains).

I could make a 400 work but I don't want to go to a 600 grain arrow for my hunting.
