Forming 375 H&H to 375 Wby brass

[Karl]

Recently aquired a 375 wby and need to find out the preferred method of forming or "blowing out" the cases.

I'd imagine it'd be the same as any other fire forming. Either form a 'false neck' or seat the bullet FIRMLY into the lands, and set off a light charge of a fast powder, and bob's your uncle

 

[Why not?]

You can just fire 375 H&H to fireform to 375 Wby - no problem at all.

What I did for years was full length resize 416 Reminton. That way the brass end up the correct overall length, whereas reformed 375 H&H is a tad short in the neck.

oh, right - they both headspace off the belt, so you should be good.

Put loaded 375 H&H cartridge in chamber, pull trigger, remove 375 Wby brass. - dan

I had thought of that - but was not sure if it was best. Sounds like a time saver. Thanks for the info.
