So I bought a box of the West Coast Bullets 38spl 148gr. Copper Wadcutters and was having some issues loading this weekend.
My setup is as follows:
RCBS Rock Chucker
RCBS Carbide .38/.357 Dies
RCBS shell holder
My issue was almost every other round would buldge the middle of the case, right at the bottom of the bullet, when seating.
I have loaded a few hundred .38's with 125gr JSP's with absolutely no issues, but these bullets were just not working out...
I tried multiple different ways of loading the bullets, all with the same results:
-Light bell on case
- Moderate bell on case
- Heavy bell on case (could feel the seating die slightly contact the case mouth... didn't like that)
- Hand seating all bullets to ensure concentricity
- SLOWLY seating each bullet
Every one of those would still result in bullets that were out of spec.
The thing is I tried seating almost to the bottom (like 1.300 OAL) and would get absolutely no buldge. It wasn't until I hit bottom (1.200 OAL) that every other round would buldge the case resulting in an out of spec round.
I loaded a total of 200 rounds and got 120 that were in spec with 80 that were buldged.
Any clues as to what I am doing wrong???
I'm looking at a box of about 300 remaining bullets that I don't feel confident in loading... which to me is unacceptable.
Keep in mind I'm relatively new to reloading. I've only been doing it about six months now and only have around 4k total under my belt (9mm, 45 ACP, 357 Mag, 38 Spl).
Edit: had the COL confused. Correct COL was 1.200 not 1.120
