Perfect
I assume you are breech seating your bullets about 1/16 inch ahead of case. Do not use a wad (card or foam) over the powder or in case mouth. See how 13.5 groups, then start increasing charge in .1 grain increments to see if groups tighten. You will likely find a sweet spot somewhere between 13.5 to 14.3 grains of 4227.
Good luck and please keep us informed of your progress.

Fixed ammo 32/40  165-170 gr bullet 14.5 4227 charges thrown not weighed.  Bullets long seated to touch the rifling.  It’s the standard load 32/40 shooters our monthly club 200 yard offhand matches. Fine target load. 

Match used to be won most often with 38/55 245 gr 17 grs 4759 switched to 17 grs 4227 when 4759 was discontinued  Some of the best shots our club have migrated to 32/40. 4227 was always the 32/40 powder.

Note there is more than one 4227. I segregate Australian from Canadian and even have some old American made. Differences slight but loading 40O at a time use powder from same jug/can as a lot.

We also see variations in sight elevation settings at 200 yards about 1 moa cold day to warm day. 40 degrees to 80

Never  shoot that load from the bench or with a scope, except sometimes end of the match shoot up a few cartridges muzzle and elbow rest painted steel plate at 200. All shots about size of clenched fist. 3-4 inches ?

More than you asked for.

I shoot that match with 165 gr Meister sized .323 over 13.5 gr 4227;  anywhere from 13-15 ok
