What is the weight difference for a 20" crossbow arrow? Do you have any preference? why? I shoot 2216's now, but am thinking about building new arrows. . .

I think there are about three guys in here that should know and help out soon. I know Smokepolehall is a big aluminum guy, as is DNK. Not sure how much Dan does with them, but sorry I can't help, you should get a answer soon.

2216s are 12.02 gr./in. and 2219s are 13.77 gr./in. so a 2219 will weigh 35 gr. more in a 20" shaft. I like the extra weight and the 2219s have a thicker wall, making them stronger as well as stiffer than the 2216s. The extra weight has proven handy for me with elk, but I also bump the weight up even more with a heavier head. They have the same outside diameter (22/64") so they should both sit on the rail the same. Hope this helps.

? has been answered. Now if yer shooting deer the 2216's will do all you need. If going for bigger game Elk, Moose go with the 2219's fer the wt. I use 2213-2216-2219 and carbons, now. Ahh ? why the carbons now after all of these years. I was given them by a very good person, awshucks my friend!

So....you're saying if I was to go shoot at some hogs, the 2219's would be the better bet......I wonder what that extra 35 grains does to the fps.....I reckon I need to invest in a chronometer, huh?

Nocks and inserts also play a role in the weight game. AL inserts seem to weigh about 29gr, where plastic inserts weight about 15 gr. Nocks are similar. My next plan for an arrow change is to add 29gr inserts to bot ends of the shaft. This adds some weight and also allows the use of a pull out tool. That tool will keep me from pulling on fletching when removing arrows from my target during practice. It also seems like I will loose some FOC.

Ok.....I understood everything except the FOC. What's FOC?

deleted, dang fast reply, lol.

You can figure 1 fps for every 5 gr weight change. FOC means front of center balance point. A quick and easy way to figure it is balance an arrow and mark that point. Subtract half the arrow length, multiply the diff by 5. That gives you the per cent of FOC. Example: my gt's are 20" long Balance point is 14" from nock end. 14-10=4X5= 20% FOC. I don't measure w/ bheads on, this is close enough for me. More is better than less, up to a point.

I appreciate the information Awshucks.....You said you don't measure with the broadheads on. Does that mean you don't find the center of gravity with the broadheads on? Or does it mean you don't take the distance into consideration, just the shaft length? I'm thinking its the latter cause you really would need to take the weight of the broadhead into consideration when finding the CG right? Also, what does that tell you? What's the target FOC that you're looking for? I guess there's an acceptable range? Just keep me learning Awshucks, I'm like a big old fat sponge!! Just soaking it all up.
