heavies in the 45 acp

You are going to get every response in the book from the doomsayers telling you your are awaiting impending doom to it is wonderful to use them.
Speer list 5.2 gr bullseye for a max load with the Speer 260 gr JHP.
I would start with 3.7 or 4.0 Bullseye and work toward a good shooting load. this assuming you have a stock spring in the gun you are going to shoot them out of.
I loaded yesteday a 250 gr Magma Eng. bullet that weighs 253-252 with 10.5 gr 2400.
The Lee seats roughly as deep as the 260 gr Speer. 4 gr is over a 10 percent reduction in charge. Just work up looking for accuracy.

If you use your head and be careful there will be no impending doom coming your way. But it still is not a very good idea.

[Awsar]

never shot anything over 230 gs in my 1911s
be carful and let us know how it goes

[tacklebury]

I've shot some 250 gr. XTP's over 5 gr. Unique, but they didn't always cycle my slide completely. My go to cast bullet is a 200 gr. RNFP with 6.5 gr. Unique which is very accurate. ;)

The Speer #13 manual is one number before their #14, which is their latest. BOTH adhere to the SAAMI Spec pressure standard for standard pressure ammo.
No +P is included.
I for one do not think Speer intends to destroy anyone gun.

sgt.mike,
Try the search function. There have been many threads regarding the use of the Lee 452-255-RF in the 45 ACP.
I do use that bullet in some of my 1911's. In my Taurus PT1911, it is the only bullet that seems to group well in this pistol. It also shoots well in my other 1911's that will feed it.
Good luck, jmsj

I haven't had any problems with heavies - I use a 255g SWC in 45 acp for some real smackdown. Hits very hard for stake shooting !!! (race to see who can cut a 2x4 in half first)

Experiment to get the recoil impulse heavy enough to cycle 100%. As long as you don't hot rod it too much, shouldn't hurt anything with a stock spring (full disclosure - I run a 20# spring)

Yes, the 1911 was specced out for a 230 rn - 25 more grains of weight shouldn't hurt.
Now 150g swc, thats a booger to get to work !!!

In my opinion, having used this exact bullet, 3.1 Bullseye would be fine.

FWIW.....

This is getting toward a shape the 1911 was never meant to feed. The large meplat combined with the possible short overall loading length mean the bullet strikes the frame ramp low and late, and its climb up the feed ramp to the chamber is steeper than a round with the overall length and bullet shape of ball ammo.

Which means it is more likely to jam than something that caters to the 1911's preferences in terms of shape and length. So some experimentation is necessary, and the closer you can get it to 1.200" or so, the better in terms of lower pressure per a given velocity and feed reliability.

I personally preferred Unique when using it, in 5.0 grain charges. But then I loaded it as long as my guns would tolerate. It is not impossible to get it to feed; it's just more likely to produce problems.

Fun to play with, but not a defensive round compared to a more correct, and better feeding, bullet shape for a 1911.

I've loaded the Lee 255 RNFP (245g from WW) and found it to cycle well. What it didn't do was group right. With proper load development I am certain it would, but the Lee 230g TC is so accurate for me I didn't persue it any further.

I used W231/HP38, but I can not remember the data at this time. Trying to recall, I believe it was 5.0g which is down .3g from the load I use for the TC.

The shape of the RNFP is so close to ball that it made sense to try.

Glad I did it and I might try it again, after all, 15g isn't that much more and well within the range of the ACP.

i have loaded same bullet with AA2 for the 1911, and with blue dot for use in a S&W 25-2, at significantly higher velocities. now i have a box of 300 grain sihllouette bullets in 452 that i is gonna try.

[runfiverun]

i'd make a dummy or two and see how they feed from the mag before i done anything else.
then make a few like 5-7 of the 3 gr b-eye loads and try them.
you then have something to work from.
i'd also compare how deep they were seating to feed properly and judge the case capacity against a "normal" load.
try to educate yourself about what changes you are making.

250 gr. RNFP over 5.5 gr. unique cycles fine in this one.

[Michael J. Spangler]

for top end loads use unique or universal clays. there are a few others but these seem to be most popular.
i keep my hot 45 loads in AR brass for the 625, i don't want to mix them up with my 1911 with a standard recoil spring in it

loaddata.com has a bunch of good loads for the heavies

[PS Paul]

That boolit works dandy in my RBH .45 acp convertible- ha-ha!!!

[Tracy]

I have loaded lots of Lee 255 RFs in .45 ACP over 5.0 Bullseye, and fired them in several 1911s. I have had generally good results with that load, which is why I continue to use it.

[Potsy]

I've thought about trying a Lyman-Keith SWC in my Kimber. I think I even posted on it sometime back.
I've not tried it yet, but one issue that concerns me is of a more practical nature.
My Kimber hits very close to the same POA with 200's and 230's. I wonder how much higher my 260 grn. Keiths would hit?
I love to experiment. Wish I had more time to. But I usually stick with loads that hit close to each other so I don't have to play with the sights.
Any input in that department?

Have used the 454190 (Lyman 250 RNF) in the .45 ACP Ruger Blackhawk---5.0 grains of Bullseye for 850 FPS muzzle velocity...was quite accurate.
