I’m trying to reload some 375 h&h and am having a weird issue
The cases size fine with minimal effort but when I go to seat the bullet, the case opening is too small and the bullet bulges out the side of the neck before the shoulder making it difficult to chamber
I’ve tried a few different bullets (Speer, Sierra,Hornady) and all have the same issue
I’m thinking it’s the expander in the sizing die that is causing the issue
It’s a Lee die set and the expander measures .306 which I think is for a 308 and not a 375
The bullets obviously measure .375
With the expander out of the die and sticking it in the neck of the brass case it’s like trying to put a small d!ck ina big hole it just flops around in there so it obviously isn’t doing anythjng
What do you guys think?

As per Richard Lee book, "Modern Reloading - Second Edition" you want about 0.002" "squeeze" when you seat the bullet - so you want the sized hole to be 0.373" for a 0.375" bullet, as per him. Like you, I suspect 0.306" is WAY Too Small for a 0.375" bullet. I looked at the cartridge and chamber drawings on SAAMI website - they call out circa 0.402" for neck diameter on the cartridge with bullet in it. So that would be 0.375" for the bullet and 0.027" for BOTH cartridge neck walls - so neck wall about 0.0135" each.
