Bullets for 10mm and 40 S&W


December 30, 2012, 07:48 AM
I have two Glocks in 40 S&W and I am in the process of buying a Delta elite in 10mm. I generally use 155 and 165 grain bullets in the 40's but I am wondering which bullet I should buy for the 10MM, that will give me optimal energy and precision, that will also work in the 40. My Glocks are not target guns or "game getters", they are strictly for self defense. The Delta, on the other hand, should be pretty accurate and able to pack enough wallop to take down a good sized hog or deer. I am thinking that bigger is better for the 10MM but maybe the 165 would be just fine. By the way, while I will probably find a FMJ for practice I am wanting a Hollow point for most purposes, so what weight bullets should I be looking at.

180gr XTP powered by Longshot.

That is one of the bullets I ws planning on trying, so thanks for that.

I would try different 180gr bullets because your gun will prolly like one over the others. Try the Sierra 180 JHC and the Gold Dot.

I plan on starting to reload 40SW for my glock 23. Just got my Lee dies in the mail. Just bought some 165gr plated FP Bullets from Berry's Mfg for practice. I plan on starting with the minimum Power Pistol loads in the Lyman's manual

Like 918V said, Sierra or Gold Dot. Mine shoot's well with a 170gr and I plink with a 135 gr. :)

All of my 10mm handguns, both pistols and revolver, are all more accurate with 200 gr. bullets. There are some excellent 200 gr. bullets available, in both jacketed and cast.

For just general plinking and shooting, I'll run 180 gr. bullets in both my Colt Delta Elites, Witnesses, 1006 and S&W 610. The 180 grain weight is a good all around bullet for this caliber, but for more serious work, I prefer the 200 grain weight.

Hope this helps.

I run either the 180 or 200gr XTP over AA9. Great bullets.

IMO Gold Dots are too soft for magnum velocities. Sierras are very frangible, fine for SD but not for woods carry.

I'd shoot 180's in both of them..
The standard bullet weight for the .40 S&W was 180 grains when they invented it.

And that's the only factory loaded bullet weight you could buy for a while.

Just for plinking or casual target shooting, I like the FMJ bullets made by Precision Delta. The prices are pretty good, they ship quickly, and I use their 180 gr bullets in a Sig Sauer Elite P226 and a Glock 23 all of the time. I'm a fan, and usually order 2k-6k at a time.

Glad you chimed in here. Sounds like you really like the 10mm. You gave me some good advice on the 357 Sig a few years ago. What powder are you loading under the 180's and 200's. Thanks to everyone else as well, I will probably try the 180's in both but I doubt the 200's will work in the 40. I will probably load a lot of 180's and keep the 200's for hunting and serious target work if it turns out they are more accurate than the 180's.

I'd run a 200 gr. LSWC in that Delta and never look back.

If I was dead-set on sharing bullets with the Glocks and Delta, I'd go with a 180 gr. XTP.

Xtreme 180's. Heavy plated and accurate. HP is a continuation of the old 'dum-dum' wives tale.

I reload for 10mm and 40s&w. I've reloaded everything from 155gr up to 230gr, and by far my favorite is both cartridges is a 200gr WFNGC hardcast lead bullet. I get mine from Double Tap (the bullets, not the loaded ammo). I use them for 40s&w Glocks (G27, G23, G22, G35, G24) as well as a 40s&w FN Hi Power, and for 10mm in a Glock 20. These bullets are gas checked, so there is no leading whatsoever and you can drive them pretty fast if you want to, but you don't really need.

I carry 165gr hollow point reloads I've worked up for daily carry, but for woods carry in either the 10mm or a 40s&w the 200gr loads are hard to beat. They also seem to be capable of better accuracy than the lighter, shorter bullets.

By the way, I shoot non-gas checked lead bullets in all of my Glocks and have zero leading as long as I use a bullet that is harder than 12 or 15 on the Brinell scale and don't try to push the bullet over 1,200 fps. I've tried after market barrels for the Glocks and they did lead a bit. The polygonal rifling on the factory barrels works great with harder lead alloys, gives great accuracy, and does a good job of stabilizing heavy-for-caliber bullets.

By the way, I found the 230gr WFNGC hardcast bullets didn't stabilize properly in the Glock barrels. No problem with feeding or pressure, but I don't think the twist rate on the typical 10mm or 40s&w barrel is suitable for bullets over 210gr.

Good luck.
