Bulletdesigner, did you come up with a certain design for a bullet that would alleviate some of these issues with the 45 ACP loading?

Most all of my loading's for the 45 ACP cylinder use 200 to 225 grain solids and hollow points. Bludgeoning something with a heavy semi wadcutter doesn't kill better and most of the time you loose it by not being able to find it unless placement is spot on. The 45 ACP case doesn't have the capacity to drive heavier bullets fast. You relie on precise placement to do the job. Any of Lyman's 200 or so grain target bullet work well as solids. MP Molds has several hollow points that expand and kill pretty well also.

FWIW find someone who is doing it. We see a like issue flush seating wadcutter bullets in the 32 S&W Long. The case makes the difference. Some brass works, many don't. Starline even posts a warning about such things on their 32 S&W Long brass. If you really need the bullet weight a custom SWC mold with a longer nose might be your answer.

That is great advice. |

The cylinder throats on Ruger .45 convertibles are tight, typically .450-.451 and to seat bullets out having a full-diameter front driving band you want to have the throats honed to .4525-.453" diameter. I had this done to both cylinders on mine by DougGuy and it hugely improved accuracy.
I load the Accurate 45-264H seating it to the crimp groove and size the bullet .452".

I went out and tried five different loads with the 255 gr. SWC - Unique, Blue Dot, 700X, Power Pistol, and Titegroup. I have a Ruger Convertible and the throats reamed to .4525. They all shot two to three inches at 25 yards. That is not all that great. I get MUCH better groups with the 200 grain H&G 68 bullet or the 212 grain H&G 78 bullet. It was a fun experiment but I like the lighter bullets better. I will try these loads in one of my Smith 625's tomorrow. Should be fun!

The accuracy potential of the unaltered factory product isn't to be trifled with. There is no need to alter anything as it produces match grade groups as it is. Load for it and it alone. Doing so will get you better groups than the normal spec'd guns.

Doing so will get you better groups than the normal spec'd guns. That may be true if you can afford to shoot jacketed bullets, which is what Ruger dimensioned the guns to shoot. I never had any luck shooting cast bullets which had to be sized smaller than barrel groove diameter to chamber in the gun. WRONG ANSWER. |

^^^^^^^^^
You should probably read what I've written in this thread. First page, last post. You need to load for the gun, not ammo for every other gun on the planet. It does make a difference.
Your second statement is an unacceptable condition also.
renton10x in the posts above altered his... with abysmal results. There is a way to help that condition, but let's see if his lighter bullet produces acceptable accuracy.

Back in the day when ammo was cheaper, bought several 1000 round cases of 45 acp for $120 each. Still using it some with my 1911 and convertible Colt SAA. This ammo is Spear GI 230 grn. hardball and shoots lights out. I load my SAA out of a 1911 mag and it works slick, believe it or not...the SAA has softer recoil than the 1911....lol

My OM Blackhawk convertible has the same issue, x101airborne. Bullets have to taper from the case mouth or cartridges won't chamber. Like this.  The 45 Colt cylinder works fine with 452 bullets even though throats all measure 0.448 and 0.449. Go figure. |

The 45 Colt cylinder works fine with 452 bullets even though throats all measure 0.448 and 0.449. Go figure. Isn't that the frustration of it all? I can push a .4515 jacketed bullet through all throats (both cylinders) with finger pressure. The 45 Colt cylinder chambers just fine with .452 sized bullets. I guess it is going to take some experimenting to get this ACP cylinder figured out. I did load some Lee 255 gr RNFP bullets and they chambered just fine. I fired them right away so they didn't wind up in a semi auto. They were mid range charge book loads for 240 grain jacketed bullets, I just didn't want the extra nose to jam in the lands of a semi and cause an increase in pressure or a slightly out of battery firing condition. |
