45acp Cartridge Overall Length?

I reloaded 100 rounds of 45acp using a 200 grain plated Berry Bullet. The cartridge overall length is 1.295. All of the bullets were seated and crimped at that length. Should I pull every bullet and redo? Or can I just seat them to 1.250 and re-crimp? Is there any danger in shooting the bullets at 1.295? The bullets do cycle in the gun when I manual do it. Any thoughts? Thanks.

You probably do need to reseat them. Hopefully you haven't crimped them much anyway, since (a) it's .45acp and it doesn't ever want to be crimped much; and (b) plated bullets like Berry don't like much of a crimp in any caliber. Try using your seating die to jam them down in there and watch for any flaking of the copper plating or damage to your case mouths. Then, if they'll cycle manually, I'd say you're good to give them a try at the range.

Which 200 Gr Berrys?

I load the Berrys 200 GR HP at 1.200 with good success. Shoots great, and cuts good holes in targets. Even better holes than the Hornady 200 Gr FMJ-CT (SWC) Go figure.

As ChristopherG posted, if you haven't overcrimped, you should be able to seat them deeper.

1.295"Yikes!
Just seat them deeper.

1.275" is MAX SAAMI length for any bullet in .45 ACP.

At 1.295" you very likely have the bullets shoved into the rifling.

You should load them to about 1.250"

Just carefully push/seat them deeper but don't force them, I load 200 grain berry's at 1.200, from memory. As stated by the experts here, 1.275 is max by the book.

Just for the heck of it I messure a 45acp 230g FMJ "White Box 100Rd Pack" It messured 1.275 Why do you think Whinchester seats there bullets that high? Hodgdon list them at 1.20.

No RN .45 bullet needs to be, or should be, seated that short.

1.265 is a good place to start with RN. I had some mags that did not like 1.275, so I stick with 1.265.

All GI issue 230 grain RN-FMJ hardball & match ammo I have measured is seated to between 1.266" - 1.271".

1.275" is SAAMI max length for a standard profile RN bullet, and it seems Winchester is seating to that length.

No idea how or why Hodgdon came up with that 1.200" but it is way to short.

It would be tedious, but I would give each one a tap or two in a kinetic puller to loosen the crimp, then seat them deeper. 1.25 OAL functions well for 200 gr RN in my guns.

It's not like a roll-crimp has a death grip on the bullets.
Unless done extreamly wrong, the taper crimp has nothing to break loose or loosen.
It should be just barely kissing the bullet without cutting into it.

Just seat the dang things deeper is all you need to do.

The 1.200" OAL figure represents the minimum OAL and the pressure generated at that case capacity. It does not automatically mean Hodgdon is wrong.

If you recrimp a plated bullet, make sure you push down hard on the bullet with your fingers/hand afterwards to see if you can push the bullet into the case. If the bullet is loose in the neck of the case, the bullet can seat deeper when the slide slams the loaded round against the ramp resulting in higher chamber pressure.

Reseated all bullets to 1.25 Will do a range test on Sunday. Thanks for all of the advice!

It does not automatically mean Hodgdon is wrong. Yes, it does.
The whole world seats 230 grain RN to 1.270" or so.

An inexperianced reloader should be able to pick up a Hodgdon manual and get what one must presume is a recommended OAL for a 230 grain RN bullet.

That they list it .070" too short is wrong.

It does not.

There are 230gr RN lead bullets with various ogjive profiles. Lee, for example, offers a mold with a 1R profile that you seat to 1.200" OAL. I seat my Lasercast bullets (2R ogjive) to 1.250" OAL.

Not all 230gr RN bullets are seated to 1.270" OAL. The 1.200" OAL published by Hodgdon is the shortest possible scenario, a safety measure. Can you imagine seating that Lee 1R to 1.200" using 1.270" data?

I just pulled out the Speer Manual #13. It list 230G TMJ at 1.260 OAL and 230G LRN at 1.270 OAL.

But those are Speer bullets. Not all bullets are profiled like Speer's. The Lee bullet I described above will not chamber in most autoloaders at a 1.270" or even a 1.250" OAL. It will hit the rifling prematurely.

COL depends also on bullet design. Speer Gold Dots are usually recommended at 1.20"

Every .45 Auto round I've loaded with a 200gr or 230gr RN bullet has been seated between 1.250" and 1.270" depending upon the bullet profile. More times than not they are between 1.260" and 1.270". The bullets I'm loading right now are seated to 1.260" and work well for me. Sorry, I don't know who made them, they were given to me in a bag... (I never say no to free bullets!!)

357mag357, don't forget the report on those reseated rounds...

The Berry 200g RN copper plated bullet with 4.2g Clays 1.25(COL) was good. Mild recoil and accurate at 25 ft. The same bullet seated at 1.22 was just as accurate how ever had slightly more recoil do to the increased pressure. The bullets fed well in the gun which is a S&W 1911 5inch barrel. The cases were also very clean after firing. The last bullet tested was the LEE Tumble Lube 230G LRN. I used Rooster Jacket instead of the Lee Lube which produces less smoke. The bullets were loaded with 4.0g of Clays and seated to 1.250 COL. This load was mild to shoot and was more accurate then the Berry 200g copper plated RN bullet.

I loaded .45 230 gr lead RN to an OAL of 1250 for over 40 years for my 1911's. Six months ago I purchased a kahr PM45 for a vest pocket BUG and found it would lock the slide out of battery and required a tap at the muzzle to free it. I started reducing the OAL until I reached a nominal lenth of 1235 and it runs fine. I reduced it 1220 started to having problems again so I stayed at 1235. The 1911's run the 1235's as well or better than the 1250's.
