I've used 5010 with CB's in some, possibly all of the rifles you mentioned. Assuming your K-31 and M-N are in tip-top condition, try 47gr. + .7cc Grex with 162-195gr. CB's in the K-31 and 48gr. + 1.0 cc Grex in the M-N with heavy CB's (e.g., #314299). Btw, you should use LR magnum primers with 5010 and should store the loaded rounds primer up so the Grex doesn't migrate. Lastly, unless you have an Ohaus Duo-Measure, be prepared to use a dipper + scale to charge your cases and also to push the unburned poweder out of the bbl. after every 5-10 shots.

I've used 5010 in alot of my cast shooting. I have found that the more overbore the caliber is the better it burns. I also use a small charge of some faster burning ignitor powder, but this is best left alone by novice reloaders. 5010 does tend to leave the bore dirty besides leaving unburned powder granules. Other then that I don't think it's too bad of a surplus powder and it's cheap.

Joe; what are the overbore calibers and "more "overbore calibers you have used it in? I've never heard you mention shooting any of these calibers before.
