6.5x47Lapua Hornady (Stoney Point) .375 Headspace bushing

[deeangeo]

Does anyone know if the Hornady (Stoney Point) .375 Headspace bushing can be satisfactorily used for measuring the 6.5x47Lapua dimension from midway on the cartridge shoulder to cartridge base?

I know the guage can be used with 6.5x55 SM Cartridges, but of course the cartridge case shoulder angles are different @ 25degs. on 6.5x55 SM & 30degs. on 6.5x47L

​Is anyone able to tell me please? ATB

If you look at the cartridge spec, http://accurateshooter.net/Blog/65x47diagram.pdf you will see the datum diameter indicated at .377 inches, so the bushing you have will be fine. Regards JCS

I have that data JCS, but was unsure of the .375 bush usability with the 6.5x47L case. The ID on the bush I have measures at .370" / 9.4mm.
The drawing shows the datum line dia at 9.58mm.......so I'm unsure?

Of course, I'd be pleased if the bushing is OK to use for setting up the F/L sizing die...

Am I being too pedantic? Cheers, ATB
