    Handi-Rifle 16" Barrel Subsonic .357 Loads

    Post by Cornmastah on Tue Apr 08, 2014 7:28 pm

    I purchased a .357 mag single shot handi-rifle with the intention of making an inexpensive quiet thumper rifle to use with one of my suppressors. I had the barrel cut and threaded to 16.5" and put an inexpensive fixed 4x scope on it. Anybody have any heavy bullet loads that run about 850-1000fps out of a similar gun or lever gun? If not, I will update this post as I try out new stuff and figure out the best loads for my purpose.

    Don't load any .357 Mag. Sorry.

    Do you cast or have a friend that does? There is an interesting thread going on here:
    http://castboolits.gunloads.com/showthread.php?236689-9x33R-Whisper-250g

    around 250grain cast bullets (designed for 35 whelen, 358WIN) in the 357mag. Jacketed bullets would be a concern about too much engraving force needed and may not leave the barrel.

    Ooh! That WAS fascinating. And the comment about being able to do a lot of things with handloads is totally true. I don't cast, and find lead bullets to be a bit of a problem shooting cleanly, so I tend to shoot pistol stuff with plated rounds. Just because they shoot so much cleaner vis a vis leading the barrel. But I shoot my .45 Colt with lead bullets as that is what SASS requires. i have thought about shooting the Black Bullet, a covered lead bullet that won't let the round lead your barrel but otherwise acts just like lead. It even looks like lead - sort of. So you could get away with it at a match.

    Sometimes I wish I cast, but then I think of the ventilation issues and don't go there. I also wish I actually knew how to swage bullets. There is a guy named Jim Fleming who makes all his own jacketed .224 bullets and he claims his loads are far more accurate than anything he has seen. I believe him. But he's a machinist so it is easier for him to approach some of these kinds of projects.

    I do not cast my own bullets YET... However, I usually buy and load up cast bullets for several calibers due to the cheaper cost and the fact that they are easier on my steel targets. I will see if I can find someone who makes a similar bullet commercially to those used in the link you posted, thanks for sharing.

    Just an update for this project... I special ordered the 250 gr bullet mold from RCBS which should arrive by the end of September.  Very anxious to see how it will work in the handi-rifle. I want to powder coat it and see if I can find a decently accurate subsonic load. This will be cool if it works.

    An update to an old thread... RCBS never sent me the mold, but I ended up picking up a 250 gr mold from the NOE mold shop for very cheap this last weekend. I need to find some time to cast a few and then start load testing...

    Very interesting.

    Any ideas on how you'll find any pre-existing load data for a 250 grain 357 mag load? I guess you could probably start with a forgiving powder, like Unique, and work up slowly if you need to.

    I thought I've come up with unusual handloading ideas in the past, but you are the master.

    I was going to start with "forgiving" powders like Trailboss and Unique. I might try using Bullseye if I can't get the velocity that I need with the other powders.

    I ended up testing out a "full case" of trailboss, loading the powder to the base of the bullet without compressing it. The loads worked pretty well, but the velocities were a tad slower than I was hoping for--only running around 850 fps. I hoping to be able to get the velocity up to around 1000 fps. It was a nice fun/quiet load though--which hit the steel plates pretty hard.
