So you're just using a .223 bushing die with .243 range bushings?
Reloading data seems pretty sketchy for 6x45. Can't seem to find just what l want. Also, as popular as .243 is, I expected to see a
better selection from Sierra.
Yes, I'm using a Redding Type S .223 bushing die with .243 range bushings.
This was my original set up. Redding Type S .223 bushing die, .243 range bushings, Redding .177-6 mm sizing button.
The sizing button is extra. I no longer use it in favor of the mandrel expander.
I found I get better concentricity with the mandrel because it free floats in the die.
The Redding expanding button screws on the shaft, so it is solid and may not center itself.
As to the specific bullets you want to use.
The Sierra 95 gr. bullets are really long for the 6x45mm cartridge in an AR platform.
There seems to be no load data for that specific bullet with the info I have. Sorry.
87 gr. is the highest weight I shoot in this caliber.
I went 6.8 SPC for bullets in the 90 gr.-120 gr. weight class.
And 110 gr.-168 gr. is in .308 for my M1A.
