I saw a thread from another forum that QL has it at 84g. My WAG is that you get more after being fire-formed with full load.Thanks
That is impressive..

My load data is all at my other shop, but the powder of choice for the 6RPM is 24N41. I tried every powder in that burn range.Mind sharing your powder/bullet/velocities with that 27" combo??
Mandrels should work fine in steps. Anneal the neck-shoulder junctions well beforehand, and use a neck lube.
As pointed out by @Mikecr, annealing is your friend with this project. I have done it without and it can be quite the fail....
Maybe you could get a 6.5 RPM bushing die, then just have the die modified to accommodate the larger neck diameter of the .270 version. It would only be a small amount of material to remove, and anyone with a lathe should be able to handle that. Then you would just need to get the appropriate size bushing.
I look forward to reports on how this works out.Thank you for that info. I had forgotten that the ex-neck jct. might have a bump in it. I had to trim when I created a .338 version of the 300H&H (named 330HNH) some years back.
