I was going to buy a Lee collet sizer for my 303 , but I have not made it to the gun shop to order one.
I was cleaning the reloading bench and picked up the carbide 32 H&R mag dies .
I had a brain storm or brain fart depending on how you look at it.
The 32 H&R mag is .337 the 303 neck is .338 .
Sizing is by touch , you can't run the ram all the way up .
I sized 50 of my Sellier & Bellot cases ( the best 303 cases I have ever used) touched the case mouth with the M die and loaded some water droped Lee C312-185 over a charge of AA 5744.
I do not touch the shoulder due to the oversized chamber .
When needed I bump the shoulder back with a bored out F/L die , a touch but leave the body alone .
I was at the range Sunday AM and got to try the loads out .
Best group was .85" ( some luck )
The rest were about 1.5" -2" , this is caused by my eyes not the gun.
I am not saying to run out and buy a 32 carbide sizer , I had it , it worked great .
AND I an a cheap SOB that hates to spend a nickel if I can make it
