Carbons Splintering?

[stickbowhafe]

I was wondering if anyone else had this problem: I switched to MFX classic 500's which fly incredible out of my widow PLII (55@27). But, while turkey hunting this spring, I have splintered out the end of the arrows 4 different times using magnus bullheads.  Too much torque for the end of the classic shaft with a hidden insert due to the size/design of the bullhead? Did not have this trouble last year with carbon express and a typical insert.  Is it the hidden insert design causing my issue?  

The good news is I have been blessed to killed 3 nice longbeards this spring. All head shots with the bullhead.  I love the magnus bullhead...it really works for me and magnus is second to none standing behind their products.

Thanks in advance for any advice or comments.

Take a look at the thread "Explain Footing on Carbon Arrows" about 5 down from this post.
Seems a lot of guys are footing HIT arrows.
Looks like a pretty good idea.

I find the glue you use can make quite a difference to this sort of thing.

If I use an ordinary glue and then shoot my house which is brick,the tip can often be driven right back into the arrow shaft.

Do the same with inserts that have been glued in with a good two part epoxy,an it doesn't happen,,,,driving the head back that is,,,not shooting the house,,,I still do that now an then.

It sounds like you may be experiencing some issues with the torque because of the long arms of the bullheads. My formula for a very tough arrow: scuff up the inside of the shaft, the insert, clean with acetone, apply JB Weld (the slow cure kind), then foot using a portion of aluminum arrow of the appropriate diameter approx. 2" long using the same JB Weld to apply. My two limbsets on my Morrison (59@27 and 63@27) can't break Axis 340's or 300's prepared in this manner, even the occasional whack against an unseen piece of granite the size of basketball or larger or the purposeful shot to repel attacking concrete blocks (which aren't nearly as tough as the granite). An off center hit is very hard on any carbon...and I suspect any wood or aluminum would give up the ghost long before a carbon prepped like this.

A key factor is making sure you use the proper glue.
If the glue breaks loose and allows the insert to push back inside the shaft, it will break. Clean the inside of the shaft and use epoxy, grip tip, or similar quality glue.

Thanks Gentlemen, this helps.
