I will be shooting a hoyt buffalo at 50# and I want to shoot the easton axis for the durability. I pull 28" which should put me right at the 50# mark. I have checked the charts and I look like I am right between different sizes. Can someone tell me what I should be shooting.
Thanks

An Axis 400 29" to 30" long would be my best guess, with about 200 to 250 up front. Everyones shooting form And bow is a little different though? But the latter combo works for me at 50# 400 Axis 30" 250gr up front 550gr total, 11gpp of bow#.
I am shooting Axis FMJ's cut to 29" 340s with 200gr(5/16ths) points out of a Schafer Silvertip drawn to 26 and 3/4" @ 52Lbs. Fly great with the bare shafts grouping right in line with the fletched arrows. With your longer draw/arrow length I think this setup or a 400 might do the trick. I really like the FMJs, very tough and penetrate well. Good luck getting it matched up.
400's
I have better luck with the 500's with 225 grains up front.
I'm shooting a 50# Morrison ILF, with a 28" draw, and using the 400's with a 175 FP.
Why do I need a heavy point? Would adding brass inserts and a 125 gr point work or adding weight tubes work to bump up the weight? What should be the minumum weight for my arrow?

I would go with 500 because carbon arrow shafts tend to run on the stiffer side and if you are close to two sizes it's best to go with the weaker size. It all depends on what point weight and how long you keep you finished arrows but i think at 50# the 500 will work great.
i have also found the axis arrows to be on the stiff side. i believe 500's would probably be the best place to start.
500 Axis should be plently even if you shoot a 250g point. In my experience 400's will be way stiff.
i shot a 50 at 28 bow cut past center,and it liked the 400s with 150 up front.with the buffalo cut past center youll be able to get away with a stiffer spine with less weight up front.
It looks like you better get one of each 400,500 and try them for yourself and let us know what worked for you and the buffalo.
I will jump in, if you are pulling a true 28" and 50lbs a 500 will definitely be too weak.
I shoot 500 with 225-250 grains from my 50#@28 longbows. 400 is too stiff for me...Doc
The difference is the buffalo is cut past center
500's IMO!
I have a buffalo and you are going to be right on the line with both those shafts. I would suggest deciding on what tip weight you want to shoot and get shafts of each size and try them out, that is the only way you will know for sure and keep your arrow weight in the normal range as well. Good luck
I'm betting .400 would be to stiff. I'm shooting a bow not cut to center and draw 49 at 29. I'm shooting a Axis .600 with 285 grs up front. IF you go with a weaker spine you'll still shoot good with a lot of clothes on.

I tested some 500's bare shaft and flew great from my 50# fox breed. The 500's were cut at 28.75 inches with a 200 grain field point. Total arrow weight with a 200 grain point is about 480 grains. The 400's bare shafted were always tail right on impact.
Try the calculator on Stu Miller's page ( http://heilakka.com/stumiller/ ) It sometimes shows a little stiff imo but it will get you close the Axis are a relatively light shaft 500 8.1gpi & 400 9.0gpi and you can always add point weight. A 400 with a 300gr.( but you wont need that much up front) point is still under 600gr. finished arrow weight.
I am shooting the Axis 400's with 250 up front in the Buffalo 50@28 to get it to shoot good. My next arrow order I will get the 500's and try 200 and 250's up front. I am not sure that I am satisfied with the 400's, maybe too stiff for my style of shooting and setup.
I don't think anyone's charts get you right on--still takes a lot of experimentation. I would agree with the 400's as starting point with that much weight up front.
If you don't want to put alot of weight up front, then go with the 500.
Keep in mind a stock 29"BOP Axis 500 with stock insert, 125gr. point and 3 5" feathers will weigh 398gr.
With your 50lb. Buffalo you would only be shooting 7.9 GPP of bow weight with this set up. I'm sure the bow would be fine, but it might be a little quieter and more effective hunting with more like 9 or 10 GPP.
I'd get a test kit from 3 rivers.
Cut the arrows to the length you would like to shoot.
Then adjust your point weight up or down looking for a perfect bare shaft flight.
Arrow spine per individual is some what subjective. Everyone shoots just a little different.
My dad shoots the same bow as I do. Same poundage and always needs a weaker shaft then me.
Same draw length too. Our form, and release is different enough that I need a full higher spine that he does.
Try the test kit, and bare shaft till you get perfect flight.
It's worth it to take the extra time.

My buffalo is marked 45 pounds and I pull about 28.5. I am getting good flight out of 30inch 400s with 300grn up front. Haven't checked mine, but Hoyt has a reputation for running a little heavy with their limbs.
Full length 500's with the 100gr inserts and 125 gr fieldtips. Good place to start? Maybe good place to finish. :thumbsup:
