U-FOC question

[snowplow]

Just wondering about shafting. Kinda a 2 part question.

For U-FOC I have heard guys are using the ultra-lite carbon shafts (cant think of any of the names right now      ) How do they hold up? It seems plenty of non-ultra-lite shafts break easily. However, I could also picture less breakage simply because all the weight is at the front.

Alternatively, have any of you tried gaining U-FOC with say an Arrow Dynamics Hammerhead (double thick front)? I would imagine its definitely heavier, but all up front so maybe it is comparable and helps cut down tip weight? I cant believe how tough AD Trad Lites are. I cant imagine a double thick hammerhead.

Just curious, because I like the idea of U-FOC but dont like the idea of a fragile shaft. That is the main reason I run a carbon, because they are tough.

It is not necessary to use high spine/low weight arrows such as the VICTORY shaft but it does help if you  are trying to keep your total arrow weight down while trying to attain a high FOC

One should try to follow Dr Ashby's guide lines of total arrow weight above 650  grains for bone breeching properties . My personal arrows are Carbon Express   and are over 770 grains with 32% UFOC . I built that set up using a 29 inch Carbon express 250 with 500 grains up front and A & A feathers in the rear. UFOC can be attained using standard arrows. The new arrows make it easier    

 Victory is the latest entry  in the field of arrows and probably the one you were thinking of. Many other companies are also making high spine light arrows and I think this is big asset when striving for high FOC  ( over 30 % ).  Archers not wanting a real heavy arrow but trying to maintain weight around 650  benefit by these new arrows.

I have friends that shoot these arrows and talk to others on a daily basis and have had no bad reports as far as breakage. I do think that they  have not been on the market long enough  to have a true tests. TEST OF TIME

With skinny arrows of all kinds and brands the insert set up comes in to question. A 5/16 arrow has a internal diameter of approximately .243 the  ( skinny arrow ) 9/32 arrow is about .200 inside. the Victory arrow uses a insert /outsert because it is even small in diameter. The smaller the insert the less strength which could lead to a potential weak spot  again time will tell.

Good luck in pursuit of UFOC …..Have fun!

I have been shooting a set of Victory HVs for a couple of years and have not experienced any loss of durability from the thin walled shafts during normal practice and hunting. Victory is also not new to the market just their name is, they manufacture Gold Tip and other branded arrows before marketing their own brand.

I have an acceptable FOC %, but not extreme. I shoot a 7595 gold tip full length shaft with 325 grains up front. Total arrow weight is around 725. I have been leaning more toward wooden arrows lately and will probably go with a 300 gr Tuff head up front and just forget about everything else. While a high FOC is definitely a goal to be achieved, many folks get a little too tied up about numbers. If I ever draw a bighorn tag here in Oregon, I will probably reduce my FOC to achieve a lighter, faster arrow that I can shoot just a little further!

The HV350's have performed well for me over the past four years...confident enough that they made a successful trek with me to NZ in March.

Arrows extensilvely hunted with...utilizing 51 -52# bows:
HV350...100 gn insert...300 gn BH...~611 gn total
HV350...100 gn insert...250 gn BH...~563 gn total..used in NZ
HV300...100 gn insert...250 gn BH...~572 gn total

The HV350 dureaiblity has suprized me due to concerns over the thin walls...they have proven time and time again to be tough enough... Now the HV300's are tough.

If weight isn't a concern, you might find getting UEFOC isn't that hard. I shoot 300 Bemen Bowhunter shafts and have 31.4% UEFOC. I use standard aluminium inserts and double foot the end of the shaft for extra strength and to make the shaft line up with the ferrel of the fieldpoints for practice.

Total arrow weight, 800gr average.

[snowplow]

Thanks guys. I was just kicking this around. I would ideally like to stay around 500-550 gr. So I am not even sure how much FOC you can get with that since the shafts are only so light. I just wondered about the arrow dynamics hammerheads because the trad lites are a bit foc but with double wall thickness in front I bet the hammerheads must be pretty foc just as a shaft alone.

[JimB]

You can get more FOC for a given weight by using relatively light,parallel shafts vs tapered shafts even though many of the tapered ones use FOC in their advertising.It's all about grains per inch.I'm not knocking tapered shafts.

[snowplow]

I hear ya. I haven't heard of many using tapered shafts for foc. I was thinking along the lines that I might be able to run heavier (sturdier) shafts while not hurting the foc. I hope that makes sense.

[Friend]

snowplow...what length arrow do you require and what is the dynamic spine of the arrows that you have fine tuned for your current setup?

[snowplow]

Has any of you guys been able to achieve 30% U-FOC with a total arrow weight of under 500 gr?

I have searched for this a lot but haven't found an answer to this one.

It would be nice to find out if my goal is even possible or if I should switch gears.

It seems like it should be possible. The Carbontech Cheetahs are around 6 gpi. Full length at 32" thats just under 200 gr. Which leaves around 300 for up front on that 32" shaft.

Hey sorry for the double post. Friend, l want at least a 30" shaft but l just got the new bow so that's really all l know so far. If seems to shoot my 29" AD trad lites fine though.
