Thanks Shadow and DAVIDF, great info!  Does anyone know when Underwood might have something in stock, again?

Cool.  Just stopped by DoubleTap's site and ordered a couple boxes for experimentation in my G29.  Some 155gr. XP's for carrying and some 230gr. HC's for back country carrying, once I see how well they shoot from my gun.  Thanks again for getting me on the right track, folks.  Never worried about it much with the ol' .50DEP  , that'll blow big holes in anything!  Just need to make the little Glock a little more "upwardly versatile."

230 Grain??? You talking 10mm or .45 here? I think ONCE I saw some 220 grain 10mm hard cast, but that's the heaviest. My main reloading book doesn't have anything for a 10mm 230 grain bullet.

Welcome to the forum!

I too would suggest against the MagSafe Defenders because getting enough penetration depth with them is a crapshoot.

If you like the explosive qualities of the lighter faster rounds (I do) I would at least switch to one of the very fast 135-155 grain conventional hollow point loads in whichever bullet you like best.  They've worked well on deer as some here have shown, and get better penetration than the MagSafe offering.

Yeah, lead available, but where would a recipe be. I mean NONE of my reloading ,manuals have one for 230 grains.

Many of the rounds I load, in many calibers, are not listed in any book.  If you aren't comfortable outside the box, don't load what isn't listed.  Load development from scratch isn't for everyone, and shouldn't be in many cases.

No, that was not my point. It's just I wouldn't know off the top of my head where to find a recipe since it's so uncommon.

Well if you followed McNett's post on some of the forums you could find some of his work...
this from GlockTalk is what he posted for the West Coast &  Precision 220gr Hard Cast test (he mentioned they were HOT)
10.0gr Blue Dot WC220 - 1285fps 6"KKM
10.0gr Blue Dot PB220 - 1318fps 6"KKM
10.0gr Blue Dot PB220 - 1219fps G20
10.0gr Blue Dot WC220 - 1115fps G29 65F

using Beartooth WFN 200gr. bullets:
11.0gr. BD - 1336fps 6"KKM
11.0gr. BD - 1246fps G20

The point is, there is no published recipe. What you'll find will be what someone else did, whether advisable or not. Most are not. You've said before you stay within book loads.  How do you do that, when there's no book? The loads Shadow posted are over book for lesser bullets. I'm not saying don't use that load. I'm just saying. I use big-heavies in 10mm up to 240 gr. If you don't like lead, you can't get there from here.  The largest copper clad 10mm bullet I have and use is 210 gr.

This is why the Pull-Downs which are being done helps dispel any myths and shows what the ammo makers are selling vs. the performance advertised.  People can choose to work up and copy if they so choose.

Well, if I followed EVERY Internet site on everything related to reloading, I wouldn't have time to post HERE now, would I!   

Besides I said I have reloaded 200 grain loads, and have seen recipes for 220 grain loads, just not 230 grain ones.

That Double Tap 230 grain load is the only 230 grain load in 10mm I know of.

As mentioned above, it didn't stabilize well in Hickok's stock G20 barrel.
