Has anyone tried the FMJ 6mm's? My DL is 28.5 at 71lbs. 100 grn broad head and considering using the 50 grn. brass insert.. and the 320 spine..
Just made some of exactly what you said, 50 grain brass & 100 grain dead meat. Killed a couple hogs and a couple turkeys & so far no issues
Frank, what did your total arrow weight end up at? Was 320 spine enough?
Get the Autumn Orange. Dead sexy!
i'm in the same boat, but i was leaning towards the 5mms. Any reason why you are looking at the 6s?
I'm building some 6mm Autumn Orange shafts right now. Cut to 30 inches with a 50 grain insert 3 blazers and a 100 grain tip they come out at 477 gr.
Only reason was looking at 6mm is because not as heavy as 5mm.. but, I am not sure the 320 spine is stiff enough especially since I am planning on adding 50grn brass insert... I currently shoot GT Kinetic Kaos.. but I've never been super crazy about full carbon arrows.. I have some old Easton ACC pro hunters I may try and remove the insert from and try put a brass insert in
Was his spine enough. I get a kick out of what folks shoot for spine. I shoot a 67# Mathews with a .400 spine arrow cut to 28"s. I draw 27.5"s. I shoot 175 grain point weight without and issue. Paper tunes to perfection, perfect hole and bareshafts well out to as far as I care to shoot it. Shawn
Shawn... I also shoot 400 FMJ 28”-125 grain head out of a 70# Bow... I’ve been told they are too light of a spine but they fly great . If I turn weight down they fly sloppy... I’m sure it has to do with shooting fingers and the bow model .
Have a buddy who was shooting the 400s out of a 62lb darton ds3800 at a 31"draw, and he had heavier points on the arrow, they few like darts and the bow was the quietest I've ever heard!
I bought a whack of the autumn orange ones cause I found them half price. Have yet to build the arrows.
Mistake on my part, I have 340's. Have to agree w most of the spine comments, up until 2 years ago I shot 400's. I always shot 70-72# & the fastest Bowtech or Hoyt there was at the time. Lot of guys said "that won't work, spine is too light"! Lot of animals in Alaska, Africa and the lower 48 would disagree!
Hmm wonder how you guys get good flight from the weaker spines?
I’m shooting 29.5” .300 spine arrows out of a hour faktor with a 29” DL at 70#s. I had to reduce tip weight from 150 to 100 to get it to tune
LOL!! If the bow is tuned properly there is no reason a 340 spine even cut to 30"s will give you perfect flight with as much point weight as 175 grains. I 100% agree you can get stiff shafts tofly fine but you don't need them to be that stiff. Shawn
I shoot an Elite Synergy at around 67 pounds with a 31" draw length and use the 320 Autumn Orange with 50 grain brass insert and 125gr. broadheads and they fly perfectly. Here's one of them on a Greenland beach where it ended up after zipping through a musk ox.......
Shawn, I need a tuning lesson then!!!
I just can’t get it to work any other way, al the spine calculators seem to suggest I need 300s at 100gr if tip increases I need to go to 260s or something
Open to any suggestions and thoughts!
