Mr. Koski, please limit your posts to items that actually contribute to the thread.
Damn you Mullah!
This is like GTR used to be in the Good Old Days!
I cant speak from experience for the 9mm, but I can for 10mm.
I shoot alot of 10mm/.40 cal hard cast bullets. I have found them to be .401-.403.
I shoot the .401 lead hard cast very accurately out of my aftermarket barrel.
You can do either one of two things. First you can slug your barrel as mentioned earlier(google it if you don't know what it is. also some good videos on youtube). Second, buy small quantities of several sizes and styles of bullets and shoot them and let the results tell you.
Lead reacts different with different loads. If you shoot light target loads then a larger bullet will grab the rifling better. A hot loaded bullet naturally flattens the back of the bullet and seals the bullet around the rifling. This all depends on caliber and bullet weight of course. Also lead and hard cast lead have different alloys that make them react differently due to different hardness.
A glock style barrel also will have different reactions to leading and accuracy.
Let us know what or how your gun shoots best!
Nothing smaller then .355 for a real jacketed.
Nothing smaller then .356 (and likely larger) for lead
If your using Jacketed or Plated and it says 9mm your probably going to be fine.
Some people put a lot more thought into these things than I do. I load whatever I can get cheap. Bullet: Whatever (between .355-.356 or .451-.452). Primer: Whatever (mag or standard). Brass: Whatever. It's mostly range fodder after all.
HOWEVER, I only load up to medium velocity/pressure loads which will safely account for variations. I'll make changes only as needed.
When I get a new bullet type, I'll check the specs on it and if it's the same as one I've loaded (I keep detailed records), I'll load 100 to match that load to check 'em, then load the rest. Simple, and has always worked. I only reload 9mm and .45acp now.
Yeah, you're probably right. Berry's is a reputable company, so I'm not too worried.
Its not that I've necessarily put a lot of thought into it, its more like being afraid of blowing myself or my gun up. When you're new to something and you don't have a lot of knowledge you tend to be cautious about everything.
I run into burning houses because I know firefighting and the danger signs to look for when inside, so I'm not afraid at all. But reloading???? I don't know much so I'm just a little cautious, probably too much so.
Plus, if I blow myself up, it will be the guys I work with who will respond to treat my wounds. I'd never live that down.
That's not a bad thing. I've only been reloading a few years now and I'm still a little overly cautious.....IMO it pays to be cautious when you are engaging in something that can cause serious bodily harm.
Again, if going plated, go 0.356", like lead. After all it is a soft lead bullet with thin copper plating, acts more like a lead bullet than true jacketed. I see a lot of tumbling plated bullets from stock Glock bbls.
No such thing IMO. Check & recheck, you'll never have a problem reloading your own ammo. The guys that blow their guns up get complacent & sloppy. How else does one load pistol powder into a rifle round or double charge a case?? Check & recheck, never assume everything is working fine.
Wow. 6 year old zombie thread.
Good to see a Steve Koski thread.
Not sure where the lead comes from, but here's a comparison of .38 spl with standard lead primers. Jacketed versus plain lead bullets. Big difference.
And 6 years later .001" still makes no difference with plated bullets. Most are very soft swaged cores with thin plating and shrink or swell under pressure to fit the bore.
Doesn't anyone slug their barrels to see what size they are? I do and add .001 or .002 to the bore size for lead and plated bullets.
I have measured .356 HAP and some are .356 and some are a little more and some less like .355
I buy .357. Then I put them thru resizing dies if I need a .356 or .355. With coated bullets I sometimes have to put the .357's thru a .357 die.
Just noticed your in Houston, hope your on the good side of the water.
Well not so fast. Berrys has put out bad runs before, bullets 0.001" smaller than noted. Always mic a few out of the box, make sure they are what they should be.
