my injexions used to group....

[chenashot]

A set of strings may last a couple of years but you have to remember the center serving is constantly changing. On a fresh center serving the Injexions may have shot much better than on what is now a worn down center serving thus resulting in a slight spread in your groups. Your ACC's just might have a better fit on that worn serving now versus the Injexions resulting in slightly better groups that you are experiences. Now this is just one possible reasoning. I highly doubt is has anything to do with spine consistency.

Well said

My response was to the OP.

The FMJ nock issue is common. You need to buy a couple dozen and have them on hand so you can switch them out.

Ok, will do. thanks!

I have one on my new FMJs that fell out. It won't stay in, so I assumed it had to be glued. I'll just get some new ones then and see if it will press in. Good thing I didn't glue it! : )

Ya, you wouldn't want to glue them. My FMJ and Axis X-nocks just about have to be put in with a press they're so tight, and that's with all of my x-nocks and arrows that take them. I need a nock turner to turn them. You definitely have a bad nock, or a split arrow.

After further inspection - they just aren't straight anymore. Out of the 10 i've been shooting only 4 were straight. However the new ones are really straight, just as the old ones used to be. I'm not sure why they aren't straight anymore, but now I feel better knowing the cause.

I say that is a Gold Tip ad ?

I have about 4 left from the first dozen I bought when they first came out and they are still spinning well within their tolerances on a Ram Spine tester. Those as well as the others I have bought since then are grouping together with zero change
