Hello all. I have been loading for approximately 30 or so years but new to not just this caliber but straight wall in general. I started loading the 500 yesterday and can definitely say quite a few differences from bottle neck rifle rounds Ive been loading for.
My questions are plentiful . I am loading the Sierra 5350 JHP with CCI 250 primers, starline new brass and H110 powder, Lee dies. The Sierra manual states 44.4 - 47.9 grains. I was quite surprised at how full this makes the case. It appears all loads will be compacted or close to compacted. Now for the actual questions
Sizing the brass was pretty straightforward it was flaring the neck I had issues with. To start I set the die as per the manual. I made a beautiful 50 caliber brass bell if anyone is interested. I then simply went to ole reliable setting the die to the case and slowly increasing until the flare was correct. This is my question. When is it correct? I was able to place the bullet in the case mouth slightly more than just enough to hold it. I thought that was good but quickly learned centering the bullet to eliminate runout was quite challenging. I started to get the hang of it but do have a few that had slight swelling around the mouth of the case. How do you determine enough flare is enough?
I then started loading three rounds in increments of .5 grain increments from 44.5 - 47.5. This was my first time using Lee dies and had a learning curve with the bullet seater portion. I did realize that the seater portion floated free and not actually attached to the adjustment screw. After figuring this out I was able to seat as straight as I could. Brings me to the next question are there any tips for getting that bullet nice and straight or is it just eyeball it?
Crimping. So I read this round needs a significant crimp. I believe I achieved this and took a picture for everyone’s critique. Any advice or feedback on any of this would be greatly appreciated. Thanks in advance and sorry for the long post. I just wanted to make sure I gave as much info as needed to make a decision.
