.451 Detonics Magnum

With all the confusion concerning the .451 Detonics Magnum I decided to devote some space for it at my Detonics Stuff website. My first goal was to try and bust some myths such as "factory loaded" ammo that comes up for sale at inflated prices to the extra space for more powder. The page is not complete as I wish to add loading and ballistic info to the page. Take a look and let me know if there is anything missing or perhaps incorrect, very unlikely, as I am good listener to constructive criticism.


Click on the pistol for the page.

I posted this to ammo can also. If this is inappropriate please delete one.

Will Starline .460 Rowland brass work in a Detonics without alteration? That is, will it fit in the chamber; I seem to remember there is some overlap in the case OAL min and max dimensions.
A friend of a friend found a Scoremaster, cased, with both barrels, three or four years ago, for something less than $1000. He knew I had a Detonics, in my case, a Combat Master, and we looked his gun over, fitted a new recoil spring for .45 ACP use, and it got me thinking about converting my longslide ACP that I rarely shoot anymore. I bought 50 used cases on ebay, thought I'd first do some tinkering with .45 Super, so I wouldn't mess up the barrel/chamber if I decided I didn't like my .45 served hot, and have really gotten no farther in the "project" than shooting some +P handloads.
Where's my motivation?

Some say you can and do interchange the two.. Factory .451case measures around .944 or so... While the 460 Roland is supposed to be .957.

BTW how was the gun "cased"? What spring did you fit? Normally the 45 ACP and the .451 D/M use the same buffered spring.

I would not and I am not sure this will help or not.

I worked at Detonics as a machinist in Bellevue WA, back in the late 80's before they went bankrupt. Luckily I was able to have a .451 magnum combat master, numbered vintage, built at employee discount. My younger brother worked there too in accounting and he has a Scoremaster 7 inch barrel. I got the Halliburton case but the foam deteriorated long ago and I rescued the gun from the case. I still have 41 original rounds in the original plastic case and 7 reloadable shells with the .451 inscription on the back. I got a separate .45 ACP barrel with the gun and love target shooting with store bought ammo. I would like to find the replacement foam for the case, (fits any 1911 shape, with ammo box cutout and room for 2 ammo clips) Anyone reproducing the foam for the Halliburton case?

Be *very* careful where you get foam from, if you decide to carve it yourself.

AMT provided fitted foam cases for some of the Auto Mags. Unfortunately, the foam outgassed something nasty that pitted the stainless steel guns over time...

Need pic for foam in Halliburton case, mine went south long ago. I have 1 of 1000 but very few were produced before shutdown.
