124RMR and N320 load suggestions

[Blue Jacket]

I purchased 2k of the 9MM 124 GR. RMR FMJ TRUNCATED CONE FLAT POINT MATCHWINNER BULLETS to try in my X5.  I am looking for an n320 load that will make minor. Figured I would ask to see if anyone is using that combination to give me a starting point.  Also interested in what OAL your using as well.  

 

I swear I saw a post on this, but of course I was unable to locate it.  Thanks

4.2 grains to 1.125" will get you there and around 2" groups at 25 yards.  If you like that, get some N330 and go 4.9 grains to 1.125" and it will tighten up to just over an inch.  Off a rest of course.

Thanks Ranger.  I assume you meant 1.125 on oal
