Thread: Advice please

there are ejector rings on row of cases to left of tray......by the W on top two.

also..previously only neck sized...now been FLR ...so if dies squeazed sidewalls in even a tiny bit...it will have reduced case capacity by a tiny bit.....when you standing on edge of cliff leaning outwards...a tiny bit can be worth a lot....there are ejector swipes on other cases further back in tray too.

In regards to case sizing, was I right to size brass to bump shoulder back .002” allowing for a bolt fall with no resistance or should I have left longer so bolt closes with minimum pressure while not pushing shoulder back?

This is what I have gone to recently after neck sizing for years. 0.002 inches allows for free chamberingand removes the possibility of any tight ones. This assumes you are using a competition shell holder kit which I have found gives the most repeatable clearance.

Two schools of thought on that, when neck sizing was all the rage I used to leave it at just a bit of tension on closing the bolt.
Accepted theory then being the case neck and hence bullet had to be perfectly centered in the bore.
Now the pro shooters are full lenght sizing everytime as it is more consistent, so might as well save the wear and possibility of galling up your bolt lugs and give it 1 or 2 thou of headspace.
Its good enough for the professional shooters so thats what I do now.

I am wondering if, this being the first time the brass was annealed and therefore softer than in the past, might the brass have stretched a little more than it might have done when harder?... just a thought as this seems to be the only real change.

when deer in standing on edge of toitoi clearing 40 yards away and you cannot for life of you get bolt closed on a neck sized round,you will from that day forth be a fan of always either full length resize or partial length resizing.. 34 years ago now but I can still see the big red bitch laughing at us before turning and walking away. we didnt see many deer back then which made it all the harder to take.
