350 Legend Chamber

I have no clue how this thing headspaces but setting that aside, it would appear to have a good throat so it may be a good candidate for cast bullets.

Supposed to head space on case mouth...

But, I pulled a box of these and the OAL was ALL OVER THE PLACE!! But they shot pretty well. (147 fmj loadings)

I have only reloaded about 30 pcs. (Just got dies Friday) but I took all my brass and trimmed it to 1700. Some just touched the cutter others took near .010 off...

Also I can chamber 358 dia but need to seat little deeper as the throat seems short. My favorite 190g WFN is a no go. Even sized down to .355 it wont chamber. I have some 170 Keiths loaded to test as well as some 180 xtp’s. With H110 & 1680 using Maxi data starting low working up.

When I first got the rifle I pulled some cartridages, ran them thru a Lyman M die and charged with 1680 and a 158 xtp. They shot under 1” @ 50 yards.

Im working with this now. I didnt like the BS Winchester did. But figured as a cast bullet gun dia and bullet construction is totally adj by me so might be ok.

I dont “need” a straight walled case here. But dearly adore the 357 Max and all 35 cal rifles. So pretty much HAD TO have one. :mrgreen:

Thanks for the info, CW.

I have a hard time wrapping my head around headspacing on the case mouth. I suppose it's no different than many pistol cartridges.

Correct like semi auto pistol 380/9mm, 40 & 45

But reality is the extractor Plays a huge role.
