357 Sig how to

I wouldn't 'start' re-loading with 357 sig..........

If you already know how to reload, then by all means fill your boots. But if you don't then you need to find a manual(s). I reccomend the ABC's of reloading (try amazon.com) and at least one manual of the brand of bullets you plan on using or a Lyman manual if you only want one manual on the bench.

Dies are available, pretty much everyone I have talked to has told me they are special order (in stock at distributors) but not popular enough to warrent keeping a set or 2 in stock.

Small pistol primers. what ever flavor you find in stock.

Powder; Longshot, HS-6, Universal, 800-x and WSF are listed on Hogdons web site. http://data.hodgdon.com/cartridge_load.asp

My 357 sig shoots .355 boolits the best (go figure). I had someone tell me to try boolits in the .358 range (357 mag boolits as opposed to 9mm boolits) but that is not a good idea... too big!!! This is basically a longer 40 S&W case necked down to 9mm (.355) as opposed to 38 Spec or 357 mag (.358-.360)

I like 147gr for bullets, Cactus plains cast boolits, Berrys and Frontier CMJ in my 357 sig, 7.2 gr of HS-6.

IMHO I think 357 sig is a difficult cartrige to reload for. All the problems/hassels of reloading bottle neck rifle cases but on a much smaller scale. It would be very easy to screw something up in a big way if you are not careful or if you are ignorant of all the steps & risks involved.

Cheers!
 
Agreed, not the best calibre to learn on. I use 6grs of Unique behind a 124gr plated JHP bullet. Check data before using. OAL is critical, to short, to much pressure, to long won't feed into mag. You can not use regular 9mm RN bullets and need TWC shaped bullets (see Mystic on this board)

I also use 147gr golddots with 5grs unique
 
Im been reloading for 9mm,.40,45acp,38/357, for 3 years now, I dont reload plate or berry bullets, only DRG lead bullets, can I use lead bullets for 357 sig:confused:or have to be plated only.

I shoot cast out of mine.

Same same as with a 9mm or a 40.

You know what you are doing, sorry if I cam across as a bit of a d*ck in my last post.......

Get a hold of Jerry at Mystic, he has some 357 sig brass coming for me, you may catch him before he orders mine..... I have been reloading cases that were 1xf by me. I had a heck of a time finding new brass, and forget about 1xf brass!!

Cheers!

where can I find that special die to make 357 sig brass out of .40 brass, did you know where

You actually can't make 357 sig brass from 40 brass as it is too short...... That said you can run your 40 brass up the 357 sig die to make some cheap, plinking rounds but I wouldn't use that brass for 'full house' loads. I would do a cheap/half azzed anneal at the case mouth before you do this so that they will take the new shoulder a bit easier.

haven't seen any data for lead 357Sig, I would worry about leading as the velocities are getting up there.

I use Copper wash load data (CMJ) Berrys, Frontier etc. I would start at the bottom and work your way up, ladder test style.

I am pushing 147gr LRN @ 1100 (ish) and no leading. I also 'season' my bore with JB bore bright so next to nothing sticks.......
