Does anyone here reload .410 WSL and what do you use to do it? I've only found two threads on the entire Interwebs on it and it seems you need to re-size another case, like 7.62x49, in order to make it. Any ideas out thereon how to make some?
It's actually called the .401 Winchester self loading, obsolete since the 30s, not very effective round, bores range from .406" to .410", bullets avail. from M.T. Chambers, cases can be made from .35 Rem., I believe the rim has to be turned down or thinned as well. The whole series of Win. self loading cartridges/guns never really caught on and the .401(the largest) is the only one effective enough for deer. I heard or read somewhere that they were most popular with jail guards in the US.
Double Post, so I may as well make use of it.
Dies can be bought from CH4D, but 41 Mag dies work just as well.
There's lots of load data out there and I've tried a pile of powders, but the best is H4227 IMO. Pretty much a full case with bullets up to 210grs, and it tops 2000 fps.
While I DO NOT recommend you blindly use this data, the old Lyman #38 and #39 lists the .401WSL, USing 4227, the folowing is noted:
250gr. Cast GC
19.0 4227 = 1450fps
27.5 4227 = 1850fps
I found this on another site: Considering this will be the first reloading I've ever done (not counting my Uncles shotgun shell loader when I was kid) would you suggest I use this recipe or do you have another idea for me?
I've seen that too, and in more than one place including, the Lyman Cast Bullet Handbook (its likely source). Their loads often seem hot to me, possibly because powder burn rates have changed, possibly because vendors are more conservative about litigation these days.
I use that same data with a 210gr Cast bullet. I recommend you do the same. H4227 works perfectly with that bullet and even a full case is below max pressure, so you have a built-in safeguard. If you must go with a heavier bullet like a 240gr or 250gr, I'd drop the powder charge by 4.0 grs.
Thanks, what I have coming is the 250 grain bullet from Buffalo Arms so that's what I'll try first.
Don't want to disappoint you but B.A. don't ship bullets to Canada, at least of last month. Did you happen to order on line and haven't been notified of the dissappointment yet? If they are shipping now then great, for I have one hell of a list.
