I just purchased 1000 Hornady's 9mm 115gr FMJ from Higginson. As I was examinating them I found that there is a 'recessed ring'' at then base of them all. The problem is that it is NOT centered. I'm french canadian so I don't know if in expressing myself right.

I'm afraid that this off centered circurlar depression 'under'' the base of the bullet would make them less accurate. I only have shoot 15 of them and the results where not that good (BTW I'M a newbie at shooting, that could be my fault).

Does someone can chime in and reassure me or do I have to make them disappear ?

Post a pic and tell us more.

What distance were you shooting at and what are "not that good" results?
 
You could have shot poorly because you did not expect to shoot well. Consider that acceptable pistol accuracy is 10 MOA, or about 2.5" at 25 yards, when testing loads from a sand bag supported position. Anything even close to that when shooting unsupported is very good with an unaltered pistol.
 
I'll try to get a pic posted tomorrow. I was shooting 60 feets and they landed inside a 14'' pie plate. With no pattrens .With usual AE 124 gr ammo in can put those in the black circle , I think this circle is about 6 inches.

Those where the minimum load of HS-6 =5.8 grains. They were able to cycle the action but they were not powerfull enough the lock the slide back at the end of the string. I only have 5 more rounds of those and then I go to 6.0-6.2-6.4 grains. I'll report back (going to the range tonight).

Something to keep in mind, starting loads are not always the most accurate load.

Carry on with the load development and don't forget the picture of the "depression" as I am very curious.
 
If they are FMJ military style bullets, then that's normal. It's the way the jackets are drawn over the bullet core. The jacket is crimped at the bullet's base leaving the centre portion of the lead core exposed. Go ahead, shoot them and enjoy :dancingbanana:

Your English is great MUSH, a darn site better than my French.

My bet, is that you'll need to go to 6.4 with that powder (work it up though). To me it seems HS-6 is a tad slow for a nine. Don't throw your powder out but once you've used it up you might be happier with something faster burning like Win 231. If you want clean and fast,, and expensive :(, Vihtavuori N320 is sweet. Not to spite the rest of the guys, there are plenty of faster powders to choose from.
 
I'll try to explain a little further.
-Those bullets are FMJ/RN
-There is NO exposed lead anywhere.
-Exemple= take an rubber-o-ring made in an indestructible matter (obviusly not rubber, but you get the idea). Then you sit the bullet on the o-ring. Then you press them so the o-ring imprint under the base. That is what the bullet look like. The problem is that the center of the imaginary o-ring doesn't match the center of the bullets base.

I think too . I choose that powder after having bought the bullets and before knowing that I could perform better on 147 gr bullets.

I think the bases of your bullets look like these Hornady FMJ Encapsulated, only mine are 230 gr .45s.

I don't think it is the design of the bullet that is causing your problem, but perhaps their short length provides too short a linear axis for stability, particularly if loaded lightly. Come to think of it, I haven't experienced wonderful accuracy shooting light bullets in a 9mm, perhaps you will be better off with 124s or 147s if speeding these ones up doesn't help.

This is exactly what I am talking about!!! But mine are not centered.

I went to the range yesterday and it was not that bad with 6.4gr loaded rounds. Thanks Boomer, for the advice the next will be 124 gr.
