Title: Beman MFX 500 Classic questions
Post by: MikeW on July 05, 2008, 10:02:00 PM
Ok I need to get the weight up on these. They are cut 29" with 5" 3 fletch, arrow wraps and 140 grain heads right now and they are 475 grains. I'd like them between 550-600 grains.

Does anyone make 100 grain inserts for these?
And how do I get the current inserts out?
Heat a field point with a torch and twist and pull?

I've never messed with these HIT inserts before,looks like you need a tool to insert them?

Right now they seem to be about 3"-4" stiff using the bare shaft method of tuning. I'm hoping a 100 grains will fix it, plus I want to be shooting 10+ grains per pound. I don't want to just go with a heavier head. I like shooting Woodsman's which are 150 grain.

And what about a target or field point that matches the shaft dia.? These are a real pain to pull out not to mention they are going to wear the target out much faster.

Thx for the help in advance.

At that length they weight 320 grains,add your140 head =460 grains, and a steel insert of 100 grains which will be a total of 560 grains. Need your bow weight to find out GPP. I use the steel screw in insert all the time. Get a regular Woodsman and do it yourself. Ken

Sorry 54#@28" I pull 28" and I think I found what I need at 3Rivers after doing a search. I guess I could always just use Razorcaps and meet my goal also. I would prefer to weight the arrow it's self though so when I'm stumping and small game hunting the arrow is near the same as my broadhead set up.

Now how do you get these inserts out?
Thx again

I've never been able to get an insert out without wrecking the shaft. I think if you really want to up the weight you are going to have to use some sort of weight tube or weed wacker line. If you go to a heavier point it will probably affect the dynamic spine of the arrow and cause problems.

Mike,

I'm shooting the same weight and draw as you using the Axis 500 shafts cut at 29.5". After trying the weight tubes both 3gr and 5gr per inch I settled on the 100gr brass inserts that Three Rivers sells without using the weight tubes. The Axis shafts are 8gr per inch so I have a total of 490-500gr with the Woodsman.

I'm shooting the Beman Classic 500 arrows cut at the same length (29") with a 140 gr. field point, and a 100gr. brass insert. I'm pulling about 53#. I think Muzzy makes them?  Three Rivers or Cabelas would most likely have them. Good Luck!

Yes Muzzy makes them and most traditional suppliers will have them.  I am shoot my BW's on 54 and 56# and shoot the 500's at 28in long with my 27in draw and they weigh 520grs. with the brass 100gr inserts and 125gr tips and bareshaft perfect off those 2 bows.  I can shoot the 400's with the same 100gr insert and tip weight, but have to leave them at 30in long and they weigh around 570grs.  I do not think you will be able to get the 500's to spine correctly at your draw and weight with the heavy inserts and may need to look at the 400 size which should be perfect for you.  Mark

Like several other respondents, I shoot the 500 (in my case the ICS classic) cut right at 29" with a 100gr insert and 125 grain head.  Perfect flight from a 54# and 56# Pronghorn.  Tried the 400s, but they were noticeably too stiff.

I don't doubt that Mark is getting great results with a stiffer shaft, though.  Over the long-term, I've noticed that my shafts start tailing right (too stiff) when strings stretch and brace height declines.  Makes me wonder if brace height isn't part of the reason BW bows tend to prefer relatively stiff shafts?

Forget the tubes, brass inserts, etc...you could always add a forged head at any weight you wanted.  Just teasing but my 300 gr heads really seemed to pack a punch on the bears.  When I'm not shooting you selfbows, I'll shoot Beman ICS Hunters with 300 grain heads from my 50-55# bows...Doc

That is possible Glen, never really thought much about it but do know that BW's require stiffer spines normally then some other bows.  I am shooting very similar spined arrows on my 54 and 56# BW as I did with my 62# Bob Lee??  Never know, that I why I believe in bare shaft tuning, it will tell you exactly what your bow and draw require in a shaft.  Mark
