220 gr 10mm load

[snatch3838]

Searched the Internet info is just not out there.

So I worked up a load myself
6.7 gr accurate #7
Large pistol wolf primer
220 gr extreme plated flat point
Min charge 6.1 max load 7.1
I used mixed brass once and twice used good and bad shape
Glock 20 standard barrel
Shoot good should be subsonic but does not need to be
Dangerous pressure signs above 7.5. Accurate #7 seems to work well with heavy bullets if I wanted to brake the sonic barrier unique would be my powder choice at 3.8 gr to start super sonic is slightly above that and start at 3.6 but this did not shoot as good in my glock

I have seen factory data for 200 grain loads but not 220 grain loads. I restrict myself to 180 bullets for my 10mm. It's much easier to blow a gun up pushing a heavy bullet. Issues with case capacity, seating depth, burn rate etc. Don't create the wheel, it's been done off-label but take heed when sailing in uncharted waters as the risk you incur is higher.

On my search for data I read these post. These loads were care fully thought out and data from at least twenty sources. Before a narrowed a workable fomula up.
