10 x powder in a .17 mach IV

[Eric A]

A good friend of mine has settled on a load for his Cooper 17 mach IV using 10 x powder and Woodchuck den 29 gr bullets....the target groups are averaging in the 4s..other loads using H335 and H322 were in the 3/4 inch range...so the Question I'm posting is ..Anyone here on this forum using this powder for their .17 mach IV as their favorite powder in this calibre....thanks..Eric

I use 16.5 grain 10x and 25 grain bergers, I have never shot the gun from a bench but from the tail gate of pickup it was shooting about 3/4 to 1 inch at
175 yards.

I use RL-10X for my hunting loads with Berger 25gr Match bullets. I really like it a lot and so does my rifle. Coyotes on the other hand, not so happy about the combination.
