Just bought the last spout ar15performance had in stock, what are y'all using for sizing? I remember hearing something about the Redding 22ppc neck sizer but am not sure. If so what size bushings? Probably Starline grendel brass and 88's.
It's easiest,when one doesn't linger and Harrison had dies too.(grin)
A 22PPC neck die will do you no favors,as LBC bodies are essentially Ackley Improved(reduced taper) and plug the landing,well prior to the neck's engaement.
You'll want/need Grendel Bushing FL dies and be forced to use an expander,to chase concentricity. Seating will be intellesting too. I've got lotsa Starline and it's vastly superior to Hornady and Norma,but Lapooey STEALS the show.
Loaded Starline with 88's,average .253" diameter. So I'd personally want a .250" finish bushing,for neck tension in a Krunchenticker(bolt gun too).
Seating is made difficult,because neither RCBS or Redding make an extended shellholder,which would allow the use of various Competition Seaters,less run out concerns.
If I get time these evening,I'll go grab some pics on WTF................
Any steps in between? Thinking maybe .270, or just lube the hell out of it and take it in one pass? I had planned on using the universal 22 Hornady seater I have with the 75/88 seating stem. If that's no joy I may just send an email and see if I can get the dies sent along with the barrel.
While we're here maybe say something about velocity expectations. I have some Lever, but more 4166 and that's what I was hoping to use. Was thinking 2850-2900 should be doable.
