I size my cast 10mm bullets @ 0.4015" and I shoot them through my Glock factory barrels with no leading.  It could also be the lube I'm using as well.  Carnuba Red for White Label Lube rated to 2700 fps...

The coated bullets should be fine if they are at 0.4015" to 0.4020" but care loading them goes a long ways to maintain the coating integrity without shaving it off while seating the bullets.  Seat without any closure of the casing against the bullet while it is moving down into the casing.  With My RCBS taper crimp die I have to lift it at least 1/8" (I use a spacer ring) to stop the squeezing inward while I seat without any crimp applied.  I then crimp in a separate step to finish.

Good luck!

I measured and all of the 180gr I received measure between .4001 and .4005.  Is this a problem?

Hey guys! On my 4th or 5th reload in my glock 20, and I wanted some input on the amount of "bulge" going on , and safety levels. I haven't seen any "smiles", yet there is an obvious ring around the bottom of the case where there is less support.

Starline brass, any assortment of 180gr, typically XTP and FMJ, 8.5gr longshot usually moving right between 1200 and 1230fps.

Use a Redding carbide deluxe set, with a Lee FCD to crimp. Waiting on a Redding grx to eliminate bulge, but I know that doesn't really effect case life regardless.

Most heads measure .4020-.4023, with some measuring .4025-.4026. All loaded rounds will fall into glock barrel with ease


Thanks for your time!

I have had the best luck doing just this. I use a Redding carbide deluxe to load then use a Lee FCD for crimp. Before I noticed I was doing exactly what you warn against. Shaving off bits of coating.

The coating is "Hi-tek"? Look leprechaun green lol..

And as far as cleaning any lead that might appear in my barrel, I'm assuming standard copper/fouling solvents (hopes 9, balistol) and such won't remove the lead... any suggestions?

What should the diameter be when I mic the bullets? I'm just now learning that glock barrels have a specific tolerance for lead bullet diameter.

Hello gents! I recently grabbed a box of prarie fire arms 180gr hard cast coated bullets. I've never loaded hard cast before, and I know it's not recommended in glock barrels. I saw a video claiming that the coating on these bullets make them safe for glock barrels, but what about at 10mm velocities? I usually run my 180gr around a nice comfy 1200fps.

Also, what is the best way to clean the lead from my barrel after a shooting session? Thanks for your time!
