For decades the Hensley and Gibbs #68 200 grain SWC has ruled for as lot of things. It's more accurate and you can load them hot or mild with 2321/HP-38.
I've used it since starting in IPSC in the 70s.
Add 4.2 of 231 for a 124 plated bullet (Flat nose).
I am currently using Autocomp for a Precision Delta 124 JHP and it's working nicely. Previously with a 124 Xtreme plated 124 flat point.
Never, the very few times I've had a FTF was due to overcrimping which stretched the cases. This was very rare when I was sorting out headaches of using .355 plated bullets, something I don't use anymore.
I've tried several primers for precision rifle ammo. Best results are with Federal 210Ms. With Remington my SDs increased to the point I stopped using them.
Only problem I've had with taper crimps is loading .355 bullets. No matter how hard a crimp I used, I did get bullet set back.
I simply went and got a Lee Factory crimp die to solve the problems. The second choice is a Lee undersized sizing die but I Haven't used one yet. This is the only Lee equipment I've used in over 50 years of reloading.
