First off I will say hi since I'm a first time poster. I'm also new to reloading.
Now the dilema. I bought some cast swc 158g bullets off of Ebay back when you could. My Lyman manual didn't have one that matched what i have. So I got to looking online and Hodgon reference a swc 158g at a oal of 1.475. So I made some dummy rounds. The problem is that it doesnt crimp very far into the crimping groove. One of my first attempts turned out at 1.450 and crimps down nice and looks like my purchased reloads. Except the HSM brand reloads are 1.475. The last band on my cast bullets are approximately .025 shorter that the HSM ones.
So do I shorten the oal to 1.45? Do I still use the starting load of 3.1g of w231
per Hodgon website? I forgot to say that the 1.475 dummy round won't collapse when pushing hard against the bench. But putting a straightedge against it shows that there is no roll at all.
How do you learn to adjust for variances like this?
Just for reference I only have the ABC's of reloading and the Lyman manual.
OK that hopefully covers it. Go easy on me I'm new.LOL I forgot to say that I have been reading and searching this and another website for about a day and a half.
Thanks
