Anyone use 300 spine arrows at full length with 175 gr up front?  
Shooting out of a 50lb longbow. PROBABLY to stiff but she hits the mark. Am I missing something? Any advice would be great.

You missing a lot . For 50 pounds you need 500 spin
Your draw lenght , shelf cut ,string material ?

Gold tip ultra light 300 spine 30 1/8" 250gr point and 100 gr brass insert 640gr total fletched, low 50# bows bareshafts extremely well.
You will probably get by with the ultra light 340 with 175 up front full length.

Also you can take spin 200 and put on front 100 insert and 300 grain tip . Would be great :-)

Or take fiberglass arrow ......

Or to take proper arrow for your bow

Proper for who bowfanatik?

Grizzbear how does it bare shaft?

I am a firm believer in bare shafting, but if you are getting shafts that stiff to bare shaft, then you are getting false readings.

I shoot the 7595 trad(300 spine) out of a 65 lb at my draw bow cut past center with a 31 3/4" draw. My arrows are full length and have 300g pts in front of a standard 11g insert.

Don't you think that there is something fishy if someone can get similar to fly with 50lbs ish and shorter draw?
I have seen perfect bareshaft from stiff arrows only to find out that after bouncing off the shelf, the shaft righted itself to show a perfect bare shaft...the guy couldn't quiet the bow down as the arrow was hitting shelf.

I would love for that to work as I have 400 dz 7595's in house that will take some time to sell, but it aint.

If you can get that set up to work, you have serious problems elsewhere ...either in you or your bow.
Rather than think that you are that special...hmmm
wouldn't you prefer to figure out why you are one of the few? and then get it right?
good luck, BigJim

Proper for bow ! If you want to see performance of bow . There no reason to use that spin !

That heavy arrow was purposely built for foc and weight. VERY quiet off the bow and accurate.

Grizzbear, as Jim alludes to, many many variables and I for one think there is no cook book answer to what spine works for every one. One must experiment to see what works for them. Hopefully others will chime in with there experience.

Jim, maybe I have a problem that Mr. Jenkins did not find. For me bare shaft 500 spine will miss the bale at 25yds and 400 will be 16" right(RH), now 340 or 350 will work at 10gpp. Now this is with a metal ILF riser, plunger and flipper rest with very good performing recurve limbs.

Thanks guys. I figured I was loosing performace but it was hitting the mark right out the gate.. montana longbow. 29 1/2 draw. Ill try some other combos and try to achieve better performance. Ill try them out of my heavy draw grizzly. Anyone near South Dakota that would want to do some shooting? Would like someones advice first hand to achieve optimal setups.

I shoot Victory V-Force HV .300's (30") with 300 out of a couple of recurves I have that are cut 3/16" past center.

Shooting with bows cut significantly past center, elevated rests and plungers change things considerably.
It is not common to encounter those items on a regular basis although I know they exist. But then you also offered that set up you are shooting as a possibility yet neither of us knew what he had for a bow...but unlikely it was similar.
So I will change my statement. If you are shooting a bow that is commonly found in traditional archery today...off the shelf and cut less than 3/16" past center it is extremely unlikely that you will be able to make a .300 spine arrow work.

Jim, I always respect your comments as they ring true and come from someone with a lot of experience helping archers.

Grizz, I agree whole heartedly with Jim on the 300 spine from your longbow being stiff.. How do you tune your arrow?

I leave them full length and add tip weight as needed. 50gr insert to start with. Just shot them out of my 60# grizzly and...bullseye..  I just dont want to loose potential performance on the longbow but I like hittin where I look. Anything lighter spined seems to hit far right. Probably shooter error. I just dont want to loose performance especially penetration if the arrow isn't flexing enough. Kinda stumped on this one.. thanks again for the info

Katman        

Why you agree now ? Maybe you are right ?
 

Is not to late to learn something ,right !!!?

bowfanatic, re-read my first post, I stated an arrow set up with a 300 spine that works for me AND suggested the 340 spine for his bow. What I learned was to give corresponding info that would have helped grizz better, Jim clarified it all very nicely.

Grizz, give bare shafting a try for tuning,  http://www.acsbows.com/bareshaftplaning.html

Very similar to what I shoot.  I'm shooting 31" out of a 55# recurve with 190 gr. up front.  Bare shaft perfectly for me.  Shot animals plenty dead.

I think you're on the right track.

You're probably not over spined.  Or if you are, you may not be overspined by much.

You need to make sure they bare shaft tune for you.  And, you must double up your efforts by testing your field arrows against broadhead arrows.  

Good luck.
