FX Crown power wheel

[lamarkeiko]

I've had my .25 cal Crown for some time now and have tuned it with various H&N pellets and JSB MKII and Kings. I have only used the number side of the wheel, but I've noticed there may need to be a finer hammer spring adjustment to get the best tune, so I want to include the Letter side of the wheel. I have the new Superior liner and some new pellets I'd like to tune. The manual says that number 1 and A are on the low side, and 5 and E are on the high side. I know 5 is high, but it seems odd that A is low when it is right next to Max. I would like to know the sequence in hammer spring power order going up. Is it 1 A 2 B 3 C 4 D 5 E Max?

Thanks

Lamar

Maybe a misprint in the manual because the letters and numbers near min are the lower side and ones near max are higher side.

Thats how it is on Impact anyways.

Yeah, just keep in mind, that wheel is just an off set cam physically, so the numbers and letters closest to max are high, max is the peak of the lobe

Thanks for the replies.

I thought that the manual may have had a miss print. I did try one time switching from 5 to E while using my crony, and had a big decrease in velocity. I thought at the time I had exceeded my hammer spring too much causing the velocity drop. I will try 18.13 suggestion on order sequence and work my way up to see how it goes. I'm a little surprised I haven't heard before about a manual miss print on this forum.
