[QUOTE="Bob Wright, post: 2039304, member: 104363"] Reloder 23 works well, but your twist will limit you to 140-150 class IMO. If you work in that bullet class, just need to run some ladder tests and compare powders/primers. My 8.4 twist will run 168's easily but the 9.5 twist is maybe 160 gr. max bullet weight, cup and core style. Got to try it to see. 9.25 twist in my 7 mag would stabilize the 168 VLD Bergers, but nothing else on the planet would shoot better in that gun. It's now been rebarreld to the 8.4 twist 280AI...
