[QUOTE="Mikecr, post: 1575372, member: 1521"] The Hornady attachment doesn't have rifling, groove to bore, to be throated(like your barrel). I don't know if it would work or not as you intend here. I'm not understanding this notion. jsthntn247 was talking about matching barrel leade, (not normally established for any bullet 'style'), for measurement. Matching CBTO to that tested as best can matter. Sometimes our best seating window is pretty narrow, like 8thou for one of my combinations, which is +/- 4thou. What matters way less IMO is the tool chosen for the CBTO measure. I get by just fine with the Sinclair 'nut': [URL]https://brtshooterssupply.com.au/products/sinclair-comparator-nut-no-1.html[/URL] Same function but a step up in versatility (doing both CBTO and headspace) is Forster's Datum Dial kit: [MEDIA=youtube]--C7YmyhWtU[/MEDIA] Ultimately all that matters is recreating tested best CBTO, and any tool will work for this, provided ogive radius matches for every bullet. You can reach that match using a Bob Green Comparitor (BGC). [URL]http://greensrifles.com/New_Products.html[/URL] [/QUOTE]
