Anyone using muzzy mx4's or phantoms?

[Trailmaster]

I have both these in 100 grain for my crossbow, I am using an excalibur scope, I sighted in using 100gr field points, and was shooting a 1 inch group at 20 and 30 yards. I switched to the broad heads to make sure I got a good group, with the mx4 I was getting between a 2 to 5" group and the phantoms were way out to lunch. Is that as good as they will get? The seem to spin true i'm using cabelas carbon stalker x bolt if that makes a difference.

Do your field tipped bolts spin true? Do the same bolts not spin true when you change to b'heads?

Could be that the b'heads aren't seating true to the shaft and thus are not spinning true. Maybe try those little rubber broadhead washers between the shaft and the head.

They seem to be spinning true but I I will try the washers and see, thanks.

Maybe try your field points again to make sure all is well with your crossbow..
Althoug my bow is different (ten point) and the hunting tips are too, the hunting tips do fly consistent with the field points with my rig.
