Finallly got around to shooting a load for my Bisley with the much vaunted HS-6 powder and glad I did. Put 8 of 10 in one hole at 15 yards sitting elbows rested on knees yesterday. Bullet is a lead swc of .452+ diameter. Throats on this gun are tight like most at .451 inch. Dont seem to matter much.

Looks great. What bullet weight are you using? I'd like to duplicate your load.

Commercial cast of 250 grs + - 1-2 grs. Bevel base SWC. I started at 11.5 and went to 14 grs. All were good but 12 and 12.5 were best. I need to chrono it because book speeds vary considerably. This gun has always been one of my best shooters. Wish my eyes were as good as they used to be but at 59 it just aint there anymore.

I Discovered HS-6 a long time ago and it has become my favorite for moderate to fairy heavy handloads. Works good in .38 Spl., .357 Mag., .44 Spl., .44 Mag., and .45 Colt.
It's not what you want for the heaviest fire breathin' loads, but it IS versatile.

I also like it in my Colt Mk IV .38 Super. 7.8 grs is pretty good with the Hornady HAP bullets I have lots of.

I cut and paste this post from another site as I thought it was interesting and relates here:
I'm a huge fan of HS-6, the more I use it the more I like it. Like Skip said, the published data shows it will deliver high velocity with lower pressures than other powders of a similar burn rate. I've found it delivers high velocities without any signs of high pressure. It's a very clean powder if loaded up near the top end of the charge range. I use Magnum primers when loading with HS-6 and have found Magnum primers will shrink the SD numbers to single digits. Most of the older loading manuals recommended use of Magnum primers with all 3 HS powders. (HS-5, HS-6 and HS-7) All but HS-6 are now out of production. BTW, HS-6 = W540 and HS-7 = W571 so if you find an old recipe with those powders you can directly substitute it's equal powder. I've used HS-6 with my .38 Special +P, middle to middle heavy range .357 Magnum, heavy .45 Auto and .45 Colt working loads with very good success. You can push your 40 S&W loads up to higher velocities with HS-6, you will like the results. HS-6 works very well with lead bullets but will also work well with jacketed bullets as well. I guess you can tell I really like this powder...

I love HS-6 and shoot it in my 45 colt and 480 Rugers more than any other powder. However one must be very careful with it, as all powders, but a double charge of this stuff does bad stuff. I'm not saying why I know this but it is great stuff as long as you pay attention!

Ouch!!!! It's sad to see that gun!
I too use HS6, but in lighter charges than some here. I don't want to get a heavy load in a Colt so I use Colt level loads for ALL my .45 Colts. Frank

In reading the pc by Linebaugh about the .45 Colt linked above by bushog, I notice where he talks about the oversize chamber mouths on Rugers!?! All one ever hears about is tight chamber mouths today. Did Ruger cut big mouths previously in the sizes he mentions? Years ago I never paid any mind to such details and I do now but again as I stated above I am not totally convinced of its importance in general but I think tight chamber mouths is a better situation (up to a point) than oversized, and that is where my Bisley is at. This gun shoots 260 gr Speer jcktd bullets very well too.

My experience, with almost EVERY Ruger 45 Colt I've owned, is that the throats are usually always undersized (sometimes I get a cylinder with one or two chamber throats that are close) and the rest of the chamber (where the brass sits) is oversized, allowing excessive brass working with hotter loads. So most of the cylinder's length needs to be a bit smaller, and the throats a bit larger...

Thats been my experience also. I went back and re read what JL said and he states that chambers run .486-.490 with chamber mouths running .457-.458 inch with recent Bisley models at .455 inch. Runs counter to what I have seen and read/heard.

Linebaugh wrote that up almost 20 years ago. I remember having to send off $5 plus a SASE back in the early '90s to get the 5 xeroxed pages mailed to me. There has been some variation in throat diameter over the years.
