Diameter for 45acp 200gr SWC

[MoreIsLess]

I was going to purchase some plated 200 gr semi wad cutters on-line. I noticed that the ones Xtreme Bullets sells are diameter .451 while the ones Berry's sell are diameter .452. Which is correct or how should I decide which diameter would be best to use. Both manufacturers list them as plated.

Personally I'd buy whichever was cheapest. I doubt your firearm will notice or care. YMMV

I've used both diameters in several 45's and never noticed a difference.
Pressure will make them the same diameter in a big hurry when they get fired.

Slug the barrel.

I cast my own and size to .452 or .453.

Normal jacketed bullets for the .45 ACP are .451 and cast are .452.

Plated bullets "normally" get sized to the same diameter as jacketed. Common reloading practice is jacketed bullets are 451" for the 45 ACP, and lead bullets are .542"+. I have no need for plated bullets; my cast shoot accurately and I get very little barrel leading, and If I want/need higher velocity, I use jacketed.. Yep I tried about 1,000 but saw no advantage and the "money saving" is negligible...

Either will work in your gun and the .0005" interference fit each side of the bullet won't be noticeable...

I shoot coated at .4515

For plated, you probably won't notice the difference, but bigger is safer. No way .452 will have chambering issues in any correct chamber.

Cast and sized would want .452.

Either will be fine or the company wouldn't make them that way. I have shot both in a 1911 and couldn't tell the difference. I prefer Cast bullets to plated bullets for cost.

It shouldn’t make too much difference with plated bullets and it’s possible the .451 bullets will be closer to .452. Before I started casting 5 years ago I was buying plated bullets and they were usually a little bigger than diameter advertised

Both are fine. You can always buy some of each and see if you can shoot the difference.

I have shot a lot of .452 200 grain SWC Missouri Bullseye #1 both lubed lead and Hi-Tek coated in two different 1911's. Lead hardness more of a concern than bullet diameter in my experience.

 

[ArchAngelCD]

Lead hardness more of a concern than bullet diameter in my experience.

I don't find that to be true at all. Poor bullet fit causes more leading than bullet hardness by far. That said, there is no problem with leading with plated bullets. Lead bullets are usually .001" wider than jacketed, in this case .451" and .452" but with plated or jacketed bullets it's not as critical as with cast bullets.

I don't know that there is a Correct. I have been shooting both Xtreme and Berry's 200gr and 185gr plated bullets from a Springfield XD Mod2 and a full size Tanfoglio Witness and I can't distinguish the difference when I shoot them. So I but whatever is on sale. For now I still have a good supply as I bought the Close-outs from Bullets.com when they closed but when in need next purchase will be from our sponsor RMR as I hear nothing but rave reviews.

You won't be sorry IMO. I'm loving their 124gr JHP MPR 9mm bullets.

My next order will be their 230gr FMJ RN .45 ACP bullets.

I recently started using RMR 124gr MPR 9mm. Very pleased with them.

In a perfect world the barrel should be slugged. Barrel tolerances, no matter who makes the barrel, varies. The bullet diameter should be checked. Bullet tolerances, no matter who makes the bullet, varies.

If the mismatch of bullet diameter to barrel diameter was excessive the accuracy has always been so poor that I discontinued using these bullets long before the leading became a consideration.

Please note, the Xtremes are not the sfandard 200 profile, they are much shorter and can cause feeding problems.

I size my cast bullets to .452. They shoot well in several different 45's.
