At your current poundage go with the 340's you are better to be a little stiff than a little weak when it comes to spine.

I've got a Bowtech General at 28" and 70lbs. Would Carbon Extress Terminator Lite 60/75 arrows work for this setup, with 125gr broadheads?

looks as if I got some advice on what to buy and was told to get theeastonaxis , but was not told to stick with the 340's. I spent the money and now have the 400's. I shoot a 27 in arrow with a 65 lb weight and a 100gr reaper.

Should I panic, or do you think i'll be ok.

Roskoe , you info is worth a Ton here, thankyou for giving me the inside of this as well.

I just ran the numbers and AA is saying they are slightly weak.

Roskoe

The trouble with the 65 lb. draw weight is that you often wind up right in the middle of the correct spine for the 400 and 340 series Easton arrows. The 27" length is going to help, but you still may wind up just a little weak. Now that you already have the 400 series arrows, I would recommend just backing off the limbs a turn or so - to maybe 62 or 63 lbs. It isn't going to make much difference in speed - maybe 5 fps or so - but it could really improve the arrow flight and accuracy with the 400 arrows.

PS - Axis arrows are wonderful - expensive but worth every penny IMO.

Another option would be to try 75 grain heads.

Kanga

That will also lower the FOC, with the 100gr you have now your FOC is 10.9% with a 75gr head the FOC is 8.1% plus the arrow will still be on the weak side at 65lb.

This is why I start off with a head weight then build the arrow around the head to get the highest FOC I can.

This 10 to 15% that seems to be the industry standard these days is not IMHO the best way to go for the best arrow flight and penetration, you need to get the FOC to atleast 19%.

Roskoe

Although there is certainly something to this high FOC principle, particularly when engaging large critters where penetration is critical; practical experience has indicated that the lower FOC arrows using 75 grain heads work pretty well - expecially for lighter game like deer and antelope. Ideally, of course, he should have been advised to get the 340 series arrow. And then he could use 100 or 125 grain heads - or even heavier if desired. But now that the 400 series are already purchased, they are still workable arrows by either lowering the draw weight a little or going to a lighter head.

One of my hunting companions uses the 75 gr. Rocket Wolverine - shoot like field points - gets 2" groups at 50 yards - blew one clear through a 750 lb. bull elk in September. He thinks this whole FOC thing is some kind dated principal - like applying the old blackpowder rule that you need at least a 45 caliber for big game to modern centerfire rifles.
