These are .500 S&W rounds with the following load (my very first handloads, ever) :
- OAL 2.038" (although some were .002" longer?)
- 11.5 gr Titegroup
- Federal 210M primer
- Starline brass (pp & fh uniformed, FL sized)
- 335gr Rainier Bullets (.006" to .008" electroplating on swaged-lead bullet)
- Crimped with a Hornady taper crimp (for 500 S&W)
- Does this crimp look OK to you? Not having much experience, this looks more like a roll crimp to me but it sure as heck says 'taper crimp' on the die and the die is just a smooth bore that is apparently narrower towards the top. I adjusted per the included Hornady instructions (with raised cartridge, screw down until resistance is felt, give it 1 or 2 more turns ...I went 1 more turn but probably didn't stop at the least amount of resistance either). Note: Rainier said these bullets have heavier plating than the other bullets they sell and were designed for the 50 Beowulf. Their FAQ says to use a light taper crimp, but the guy on the phone said "the best crimp would be a combination of a taper and roll crimp, or the Lee Factory Crimp."
- How do I measure the amount of crimp when the edge is rolled inward like you see in the attached pix?
- A super fine, whisker-thin (or thinner), whisker of brass came off a couple of the rounds after crimping ...is this normal ...or not? Maybe a couple of cases were a hair longer and got belled out a bit more when I flared the mouths? I suspect the whisker is the 'corner' peeled off the outside edge of the mouth of the case by the taper crimp die ...or rolled off or whatever. Doesn't look like anything to worry about.
- Some of the rounds came out at 2.040" (and one at 2.042") but the majority came out at 2.038" to 2.039" OAL. Why the variation in length? I suspect the length changed a tad during crimping ...no? I didn't measure OAL prior to crimping but should have...
- How do you measure a crimp? Do you measure a roll crimp differently than a taper crimp? Compare to factory loads? What?
Thanks, I'll be shooting these on Wednesday I think.
