155 gr Bullets in 45 acp - Need Recipe

Inherited a few hundred 45 acp semi-wadcutter bullets, but they are 155 gr. I can't find a recipe for loading this light of a bullet in 45 acp.

I'm shooting Limited 10 with a single stack 45. The bullets are for practice loads. Don't have to make major. Just need the pistol to run and make holes in paper. A 155 power factor would be okay.

When I first started shooting USPSA back in the early 90's, I recall hearing about guys using these 155 gr bullets in compensated 45 acp pistols. The lighter bullets required more speed to make major, so more powder was used and the higher gas pressure made the compensators work better.

Anybody ever use these bullets? Do you have a recipe that uses something like Unique, Green Dot, WW-231, or Titegroup? Thank you for any help.

this data from 1991

155g Bull-X LSWC
Federal case
7.7g HP38 (W231) for 1192fps

I suggest this load be reduced to a start of 7.2g W231.

Source: 45 Auto Loadbook 2000 edition.

155 gr. LSWC cast C.O.L 1.230"

Hodgdon Titegroup: Min. 5.7 gr. 1039 fps 14,300 CUP Max 6.2 1132 fps 17,000 CUP.

The above is a cast bullet, hardness unknown. Obviously not the same bullet, only bullet weight. So start low.

Okay, first batch of reloads is ready to shoot tonight at local indoor practice match.

155 grain LSW; 6.5 grains WW-231; WW-WLP primer; 1.250 OAL; strong crimp (about .69" at the brass/bullet juncture)

The loads dry cycled thru my pistol without any hitches. We'll see how they shoot and cycle and hopefully there won't be too much muzzle flash.

The first batch of 155 grain loads ran fine at the indoor range. Pistol fed well and ejection was positive, a good 5' or more. At 12 yards pistol that was zeroed with 200 grain bullets making 168 power factor hit to the sights.

Bad news is that the muzzle flash was big time -- someone asked if I was loading with av gas.

Question -- what might be a good guess for how much TiteGroup to use that would equal the 6.5 grains of WW-231 I used in this first batch. So far I've always found TiteGroup to produce a low muzzle flash.

My local caster had a great deal on 155 swc for a while. He's upped the price to be even with the 200 now. I was shooting 5.0 Clays with very good results. I'll probably go back to the 200 gr if for the same price, not sure, I have a few thousand on hand.

155 grains .45ACP loads

I've used those bullets (from Bear Creek - moly coated) for a looong time. I've used 6.0 grains of W231 for assured reliability with a standard 16lbs recoil spring. You can a little lighter with a 14lbs recoil spring. With 6.0 they make unbelievably clean holes in IPSC target, like laser cut. Due to the design of the bullet, you definitely need a well ramped barrel. Those loads were shot out of a P-14.

I've used them in a single stack Colt race gun (dual baffle comp) with 7.0 grains of W231. They were doing 1175 fps.

Hope that helps.

7.8 gr 231 gave me 1274 fps from my AMT 7" 45 ACP. Loaded to 1.23 OAL, I did have feeding problems in the AMT but worked OK in my 5" Gold Cup. Best accuracy for me was 2.5" @ 25 yd, usually 3-4" which was not that good for either gun. This was an experiment and I did not acquire any more.
