I’ve been going with Everglades for my jacketed bullet needs (and they are great to deal with, prompt, and very cost competitive…and all prices includeshipping, tho’ of course the prices get better with a larger buy).
Generally, I’ve been buying the concave base 115 FMJ 9mms; they shoot fine, but I’ve always wondered what the concave base was about.
Their flat base 9s are getting to the point of being cost competitive with the concave version.
Any ideas, or even good guesses, what the concave bases were for?
Best guess; the concave base helps to obturate, “slug up” and provides a better seal for the bore, which prevents gas “blow by”, helping accuracy.
A .22 has a skirted base for this reason.
I thought I read that the 115 concave bullets were a little under size? Need to order soon and have always used RMR but may try Everglades if the accuracy reviews are good with the 115 gr concave.
That would make sense; undersize bullet allows blow by, the concave base would act as a “skirt” and help seal the bore.
Have no clue what their reasoning is, if bullets are, in fact, undersize.
Sounds screwy to me.
I use Everglades JHPs in 9mm. They are properly sized and very accurate.
The 124’s I use look like Zero bullets.
I was all set to buy hardcast from Missouri Bullets. I rely on them for .357, .44, and 10mm.
But finding9mm FMJ – real ones, not plated – from Everglades at the same price, I couldn’t turn it down.
You’d be amazed how heavy a medium flat-rate box with 4000 bullets can be.
Maybe someone can mic a couple 115 gr concave bullets to find out what size they are? Price on them is great, just don’t want to buy something that you can’t get accuracy out of, 25 yds to 50 yds.
Just put a vernier on some, and they’re running 0.355".
Having them obdurate to fill the bore makes a certain sort of sense. I’ve been driving them with 4.6 Bullseye, and they’re clocking 1130’sec. I’ve been satisfied with the accuracy.
Yeah, 4000 are a hefty package. My mailman is still wanked.

Ya, know what you mean, made a deal with the mail lady and told her to lay on the horn and I’ll help her out. The price is right and if they shoot worth a damn I’d like to stock up a little, You never know what the Dem’s will pull on honest Americans!
Hmmm… I wonder how much a modern jacketed bullet does this. Minie bullet were designed that way, but they were soft lead, and they were muzzle-loaded.
Another thought: Making the base concave increases the bearing surface relative to weight.
And the .22lr’s bullet is just a relic of how revolver cartridges used to be made, right? The bullet is is as big as the case, and so the back of the bullet must be skirted to fit in the case?
Lapua made some skirted bullets for aero reasons (like a squared-off boattail), but that never caught on…
Just sent Everglades a email asking about dia.If you have ever spent time looking for the best accuracy out of the 9mm and the better shooting 9’s you will know that building great ammo can be a challenge !
I’m no longer a bullseye guy, and never tried it with a 9. Do have a Smith 52, and it wouldn’t shoot fer squat with ‘beancan’ wadcutters; it wanted the skirted kind.
My one size fits all load works well enough in all of my nines.

7 yd blasting ammo is easy to make and fun to shoot, making super accurate 9mm ammo (Just ask AMU) will make you old, bald and pissy real fast, also broke!
Your 100% right on the bullets, junk won’t fly. Also remember your reloading habits are just as important, If it don’t go in straight it don’t come out straight!
BINGO! Even if there are other reasons, my bet is that this is the primary reason for the concave bullet.
BTW, that’s an excellent price on the concave bullets. Their price on American made 9mm bullets is kind of high. I think they’re getting their 147gr JHP’s from Zero Bullets. They’re price is much better on the same.
The price is good but they still are under size and with the wide range of bore dia. in 9mm it may be a crap shoot at best? The deal only saves me $20.00 over RMR and I know what they make and how well they shoot.
