155grain SWC ACCU-CAST Bullets reloading info

[Texasbeanman]

Hi All,

I'm new to this forum. Been looking at all the post for a few days and liked a lot of the replies.

So my question is, I picked up a few thousand 155 grain. ACCU-CAST SWC Match grade bullets.
The price was hard to pass up. I usually like my 180's but decided for plinking these would be fine.

My manuals have info for 150grain but nothing for the 155grain. I was figuring to use the 150 info because I'm pretty sure it wasn't adding the Alox lube to the weight.
And yes these will be fired through a Lone Wolf barrel.

Has anyone reloaded with these?
I see the company went out of business some years ago, so no one to call.

I'm looking for addition reload info with this bullet for my Glock G40.
I have many choices for powder, Power Pistol, Bullseye, Unique and Tite Group.

I built some test rounds with my Tite Group and will be trying them out today but would like to hear about others pet loads.

Thanks

I generally load Penn 180 fpl bullets, but also picked up some 155's a while ago, but haven't loaded them yet.  I've only loaded Longshot so far, but do have Power Pistol, Unique, and Silhouette on hand.   Interested in other's loads for a lead 155 as well.  Not nuclear loads, but on the warm side. 

Just got my Delta back from Hyatt Guns in Charlotte, they installed a Clark Custom ramped bbl and nite sites......it's my edc gun and now I can try some Underwood 135's.

What you are using should work fine. Disregard the Alox (or any lube) weight, as it is inconsequential and almost always less than the normal variation between individual bullets. If your 150 gr. load data is for lead/cast bullets, then it is a fine starting point for your 155's. I suggest weighing and measuring the bullets for a more accurate assessment. If they are less than .401", you will have bore-leading issues. If less than .4015, you might. These appear to be BB (bevel-base), which aids in loading, but may increase leading potential. It's best to slug the bore to really know what you have to deal with. The powders you list are hot and fast, so you'll be limited to mid-range velocities, but accuracy should be good if you don't expect full power. Titegroup can be very touchy near max loads, so be careful with that. Power Pistol should be about your best choice, with a max of 9.6 gr. @ 1.250" (start at 8.8 gr.), and these ran 1325 FPS and very accurate in my 5.2" barrel and 20# RSA.

8.8gr of Power Pistol looks like a good starting point.

deleted 2nd recommendation.

8.8gr of Power Pistol looks like a good starting point.

7.7gr of Unique would also work.

7.7 gr. Unique is pretty warm for a start with 155 gr. lead bullets. It would be OK to work up to that, but I wouldn't start there, with a new pistol and barrel. I've used that load (and more), but accuracy fell off sharply beyond 7.5 gr. in the same pistol. In the revolver, there was no accuracy loss up to 8.2 gr, but extraction became tight, meaning it was at the ragged edge of maximum over-pressure for an auto (about 40-42K PSI). A softer cast and gas checks are necessary well before that, and that is well beyond any reasonable "target" load. If you want to "go fast", there are much better bullet and powder choices. All the powders the OP listed are reasonably limited to midrange/target velocities.

Where the pre-coffee recommendation came from I don't know (probably a 155gr jacketed starting load) - I've deleted it.

A great illustration how a forum is supposed to work
