Okay, it does actually seem to be right along the cannalure...well the part of the bullet painted blue. Definitely starting in the minimum, I want some nice light loads for shooting my Colt Cobra, no wrist breakers...and besides +P isn't good in the long run for the gun anyway.Seat and crimp in cannelure and work up a load from the minimum charge and don't worry about it.
1.475" that your caliper is reading is the EXACT length listed in the Hodgdon Data for a 158gr. SWC, in .38Spl.
I would give them a good roll crimp+get to shooting...Bill.
Thank you the picture is quite useful. That's actually where I was trying to seat the bullet, though admittedly it was more trying get a number initially. When I did get it, it just looked so spot on perfect I just went for a calipers. I need to do a little readjusting (I moved the die from my hand press to my turret press.As posted, crimp into the crimp groove and whatever OAL that comes out to is the proper OAL for that brass length and bullet. Start low and work up. It is rare when this method will not fit a cylinder. The bullet makers want the product to work. But of course, as posted, the max OAL is determined by the cylinder.
Okay, that's what I was thinking. For some reason I was using the paint as a guide initially (still checked lengths). This will make adjusting my die a ton easier since I won't need to take it out until after I get close since I can use the cannelure as a visual reference.The one on the left is to show the crimp groove so one can better visualize the brass rolled into the groove.
Yeah, sometimes I'll read a paragraph on and my eyes will just glaze over, but same info in a youtube video and it all clicks.I like visual as well. Explain it and I am.. ok I think I have it, but show me as well and... oh yea, got it.
Lots of good crimp pics here.
It is with a roll-crimp as used with revolvers.its not crimping the case to the bullet per say
Case tension is still holding the bullet just like taper crimping revolver rounds which it seems a lot of cast shooters are using taper crimp instead of the roll crimp.It is with a roll-crimp as used with revolvers.
rc
is correct for an auto caliber, but not a revolver round when using a roll crimp, and as I posted, many revolver rounds need that roll crimp. Some don't.All the crimp is doing is removing the case mouth bell, its not crimping the case to the bullet per say
