Today I started by cutting up some 2413 shafts to try. I didn't this last year and just wasn't happy with the results and ended up with 2213 shafts instead. But today I shot a quiver of both sizes and in truth I believe I was getting better results with the 2413 shafts The only time the spine difference definitely showed up was on sloppy releases and then the spine showed up real quick with the 2413's impacting right and the 2213's going left. I would love to say that I have such a perfect release that this is the reason why but thats not it At least I dont believe it is Anyway...I just find it curious and I have no ability to explain why something like this is occurring. I was going to play with trying to correct an inch one way or the other and just play with tracking comparisons but to be very honest....there wasn't enough room to find error out to 25 yards which is as far as I shot or will shoot. Anyone find this to be as odd as I do?.

Yeah, I do. Probably a presumptuous and silly question, but have you checked your brace height recently?

Anyone find this to be as odd as I do?. Hmmm... If we assume a 28" arrow with a 125 grain tip with a recurve bow - Easton does not put these arrows in the same draw weight. Going to the first 2413 entry and the last 2213 entry for a shaft as listed above, the spine deflection is 0.365 for the 2413 and 0.460 for the 2213. I would expect the 2413 to shoot left if the 2213 shoots perfect, being a stiffer arrow... And the 2213 to shoot right if the 2413 shot perfect, being the less stiff arrow. About all I can say is that with a sloppy release, anything is possible! Also, if your bow allows for a nearly perfect center-shot for the arrow, I can see where both shafts might work equally well with a good release. I see that with my longbow. (When I am "on," I can make 3355's and 5575's fly the same through a longbow with a very near center-shot.) Could you be plucking the string on the 2413 and pulling your hand away from your anchor point on the 2213? Both would be in the "bad release" catagory, and could allow for what you saw. A pluck can push the string in towards your face, shooting right, for the 2413. Pulling the hand out away from the anchor point tends to put the arrow to the left, maybe for the 2213? ? Just a guess! Pulling the hand out moves the release point outward from the face, or to the right of the line of sight as we look down it. This puts the arrow impact to the left of the intended target. Plucking the string, allowing the string to roll off of stiff finger tips, puts the release point to the inside of the line of sight, or to the left of where the release point should be. This tends to put the arrow to the right at the target. What-cha think?

Nope...no shooting errors and I was staking them right in the same hole from 20 yards...maybe a 2 - 3" group each time. It is a 48 Mag and it's not a center shot although it is cut well into the center. I just find it odd that last year found entirely different results as compared to now. I know that they are not in the same range for spine and thats why last year I accepted this failing of the 2413.
I didn't check the brace but I should...thanks snoodslapper. I don't think I have paid any attention to that brace since the string was broken in.

The only time the spine difference definitely showed up was on sloppy releases... Then, I guess I don't understand what you mean by "sloppy releases" I thought the only time it happened was during release problems... I think I am missing something! Sorry.

Well, it is something of a long-shot, but I remember a very frustrating day like you described one time with my longbow and trimming arrows, changing head weight, etc. I finally checked my brace and it was quite a bit off. I twisted up the string and put it back and viola', my original arrow configuration was right back on target. Here's to hoping you get it figured out; that can make a man loose sleep!

Sorry. ;D....probably me...I tend to babble What I was saying is that both the arrows were grouping excellent and that was what I didn't understand. On the few occasions when I did indeed make a poor release , it was only then that the spine differences (relating to left/right) would show up. ------------ Snoodslapper....I checked and it's on the money so I really don't know. Guess I shouldn't worry to much unless it crops up as a negative

What are ya drawing at your length? SuperMag 48 I heard can stack a bit over 28 inches making your draw weight heavier. I had a bow that liked cedars spined 10# heavier than the norm, so I just went with it.

I generally draw 27 but hit 28" when I get excited Seriously though....27" is it more times than not and yes it does stack alot and very fast @ 28"
