Re: Model of 1910 .280 Sporting Rifle

Sorry guys, should just let this thread go, but I just watched a December 2020 YouTube video on making "280 Ross from 375 Ruger" and my sides still hurt from laughing!

In all seriousness, great that people go to the trouble of videoing this stuff and uploading to the web so we can all make more informed decisions, and if "brett" is a member here my apologies in advance. But.....

There were a couple of incorrect statements that need rectification, the main one being that reformed 300 Win Mag cases "start to separate" at the web on second firing.
Obviously, they may separate on first firing if full-length sized then fired in a rifle with excess headspace, and I can speak from experience that it can be difficult to judge minimum headspace in the straight-pull Ross. I mic the distance between the front of the bolt-handle root and the action wall to ensure bolt is fully in battery on a newly formed case, and set my forming (FLS) die up so that the bolt-handle needs a solid "bump" on a chambered case to go fully home, before fireforming.
One lot of my Norma cases is up to 6th firing with no issues whatsoever!

That said, back to the belly-laughs!

I started chuckling when the guy removed and re-lubed the case for the third time! Then the fourth, then the fifth...
Absolutely pissing myself by the time he did the twelth case removal to relube!!

...and this is not counting the 6 additional removals of case from press to redistribute existing lube around the case with his fingers!

Number of compressions in total to reform one 375 Ruger case?
Fifty!!
Yep, I counted them.

Then it took two lubes of the neck to inside neck-size.

Holy cow! Nearly 8 minutes to do one case.
And that Lee case lube must be bloody cheap in the US to go through it like that!

For the record, when forming 280 Ross from 300 Win Mag, I do about 3 small compressions, turning the case in the shell-holder each time, to get to the shoulder, then about another 3 to get the shoulder down, then maybe 4 or 5 more, rotating the case each time, to finish the job. In practice, I then bump the press "over the top" a few more times while rotating the fully sized case in the interests of concentricity, but that's probably not really achieving anything other than my own peace of mind! About 40 seconds per case!

And the thinnest smear of anhydrous lanolin applied with the fingers, wiped on like you're wiping it off, so to speak, only needs to be applied once at the start.

I was actually contemplating forming-down a single .375 Ruger case to mic the neck thickness and post the comparison here, but after watching that YouTube clip I won't bother!

Who needs the comedy channel?!
