what over all length for 10 mm

[NRFJR]

Interesting on oal as my Lyman manual says 1.260.  Maybe I should check that again as I could have misread it.  At any rate, I will shorten them and try it. 

That graphic is very interesting.

Thanks

If you look closely at the SAMI diagram the max is 1.260 it is just a little fuzzy I had to get the magnifying glass out and double check because all of the books I have (10 of them) have 1.260 as max COAL and I make most all of my 10 mm hand loads COAL at 1.258 so I had to check to make sure. Load safe and use what works best in your firearm.

I load to 1.250" pretty much all the time, not sure why but I do.
