I have a new rifle here.I have the nosler #5 manual but if anyone has proven 140gr&160gr loads it would be appreciated.RB
 
See my post on my 7 Mystic. Of course, that is a different wildcat but a point of reference. Start low and work up.

The Nosler info is a great place to start. You need to work to the needs of your rifle, not someone elses.

I've tried Rel19, Rel22 and IMR4831...Rel19 is pretty good. Rel22 gave me very flat primers and hard bolt lift at 2 grs under book max,...strange.
IMR 4831 gave the best velocity and accurracy out of my 24" King tube, 140 TSX's at 3150 under an inch consistently.
 
thanks Rembo.I was hopeing to start with H4831 and the 140gr.This rifle is long throated,the 140gr Accubonds have .225 left in the brass when seated out to the land.RB

The easiest place is probably www.sinclairintl.com out of the States. They stock Reddings. Not cheap but great dies. The standard FL set works fine, that's what I use in mine.

I use the same redding dies in mine. I have found rl-19 works best for light bullets -120 grn. and h-4350 is best for mid weight bullets -150 grn. Foe 175 grn bullets i use 7828.

I called redding to purchase my dies.They told me to purchase them from Sinclair.Sinclair as a redding distributor can sell cheaper than redding does themselves.Now I just wish mine would show up,I can't wait to try this iron out.RB
