I have heard that you might want it one or two thousandths bigger if you ware working the brass down instead of up? any comments or suggestions?
I'd sure be talking to Hart before I order any reamers. A tight neck in 6.5 is normally .290" and Hart has that neck dia for a 6.5x284 chamber listed and they may not list all their TN reamers. Gunsmith normally have good collection of throat reamers varies dia.
This is listing of tight neck 6.5 from one of the gunsmith that builds some of my rifles
6.5x47 Lapua .290" Neck ,260 Rem. Ackley .290" Neck, 6.5 Swede .290" neck
6.5x55 Rogue (37 degree) .290" Neck, 6.5x.257 Roberts AI - .290 Neck
6.5-06 Ackley .290" Neck, 6.5x.284 Win. - .290" Neck
I do agree to make up some dummy rd with bullets then talk to Hart and see if you want to go with tight neck or something else. If Hart doesn't have your rifle yet might want to deal with one of the gunsmith on this site.
