For my birthday my wife bought me a Lee 9mm 125 gr rn mould . That being said would it be better if it had the tumble lube grooves instead of the regular grease groove if you plan to powder coat? Just wondering if there would be any advantage
 
I have a mihec 130 grain 9mm with no lube groove. Makes a nice bullet. I have the 8 cavity one. Very fast to cast with. You just have to open the mold and the bullets drop. I had made 18,000 good projectiles in two days of casting.
 
If its a flatbase mould I think it will work fine. If its set up for a gas check it probably wont shoot well without one. Thats my luck so far.
 
I would think a lube groove mold would be best. Nothing to back that up, just a hunch. My molds for powder coating are all lube groove types. I hear MEI now sells molds for powder coating. I may have to try one, but ouch. One will run close to $200 by the time it's in my hands.

Or a regular groove mold and a Dremel tool. If you have a multi cavity, covert some of them. Then you have both.

I have two of the 125 gr. RN single lube groove 6 cavity moulds. I have powder coated literally 1000's of these bullets with Emerald Coatings Tool Blue and it works like a charm. The grooves easily take the powder and coverage is always 99+%. Before I sold it I also had a Lee 9mm tumble lube bullet mould. It's profile is different from the 125 gr. RN mould (the bullet nose is smaller). While I never tried powder coating these bullets their accuracy compared to the 125 gr. RN bullet was crap. Groups were poor and I often had tumbles.
The only real down side to the 125 gr. RN bullet is that it's profile is quite round and in guns with tighter chambers like CZs you may have to seat the bullets a little deeper which doesn't affect accuracy. Other than that it's an excellent bullet and works very swell with powder coating. Don't buy the tumble lube mould.
