that's pretty spicy! What rifle do you have that accepts 3.7"? I load 215 Bergers to 3.6" and they barely fit in a 700.

A late edition end of the line Rem sendero. Tried to get it fixed twice. Third time they gave me a different end of the line rifle. It has this much freebore. I installed a Wyatts long box with the use of a Dremel. Not anything like P. Ham does but it works. I pushed them faster tonight as I'm just on the edge of pressure. Probably in the 2930-50 range. Didn't bring the chrono along tonight. Shooting some larger groups to prove or disprove what I'm getting. Not the 30 shot groups others suggest, just enough to make believe what I am getting is consistent. It currently is about hunting temps now. I am not jamming the lands.

Working on a batch of 300wsm Norma brass. 3rd firing and most of them have the dreaded donut, no harm in uniforming the necks at the same time the donut is being removed.

OK, whats the dreaded donut? Is that the point where the brass is stretching and closer to the end of serviceable life ?

Where the inside neck meets the shoulder junction. Brass eventually flows from the shoulder to the inside of the neck creating a ring or "donut" at the junction. If you've ever seated bullets and felt more resistance or friction about halfway through the stroke, it's most likely a donut. The end cutter is caliber specific and only removes the donut, without cutting the inside of the neck. Maybe someone else can come along and give a little bit better description.

That makes sense. If you full size, does it prevent this? I was thinking more along the lines of a case separation that shows up first as I shiny ring slight above a belted magnum belt.

Have you ever personally experienced case head separation, Or suspected incipient separation?
You'd have to be bumping the shoulders really far with a FL die to see separation after one or two reloads

I have had neck seperation on 30/30 due to fl sizing with different rifles. Each rifle should have its own resizing die due to chamber differences. I have many 300 Win mag cases I stopped using because of the number of times they were shot and appearance of stress in the mentioned area. Which I read to be a sign of coming separation. Probably on the order of 10 reloads. Nothing last forever. Keep in mind I only anneal when changing cases to a different caliber. I used to do a lot of neck only sizing with dedicated cases for dedicated guns but even after a while the shoulders need to be bumped back a bit.

I shoot 3 or 4 rounds of Skeet every week, so I have an ongoing project every week of loading the shells that I shot the previous week. At a loading rate on my Hornady 366 loader of 5 minutes a box, that's only 15-20 minutes of loading time.
A couple of weeks ago I bought a mold for 300 gr bullets for my .44 mag pistols, so I have my Dillon press set up for them and am trying to work up an accurate load with them.
I found that the Dillon powder charge bar sticks with the fine grains of Win 296 powder, so I changed to my RCBS powder drop charger that works much better.

Those terminal Ascent bullets are really hard to come across and almost as spendy as loaded ammo. When you find them, stock up....
