Brass cleaning / removing carbon layer

[cw308]

I think using sizing lube inside the neck when seating , will squeeze down into the powder effecting the burn .

I wet tumble with the SS pins, normal run is 2.5 hours all come out "like new".

I find that one hour of wet tumbling with Dawn and Lemishine is sufficient to clean the brass for reloading. To much tumbling causes some pinging on the cases and I don't know if this effects the load or case life but never the less I choose to avoid it. I have tried minimal cleaning without removing the carbon inside the necks and it doesn't work any better than wet tumbling. I think the advantage of wet tumbling is the starting point is always the same as far as the inside of the case is concerned.

I like Ford's myself.
No matter what you do do it the same way to every cartridge ....
I don't clean anything but p pockets and outside neck/shoulder.

pockets, necks, shoulder, unless I'm trying to impress myself

For new or pin tumbled cases, I just swirl the base of my bullets around in my Imperial neck lube can as I seat.
Feels very consistent when seating, and since I never know how long it's going to be between range trips, I don't worry about case/bullet weld.

same here ^^^^^^

Interesting, has anyone compared the 500+yd. group results of lubing necks with wet lube vs. dry lube?....or no lube?

While testing “neck tension” at 600, I compared dry necks after a thorough ultra sound cleaning, dry then lubed with imperial dry media, and the normal in and out with a brush to smooth out the carbon. While not included in this test, I have shot groups at 600 with necks that were lubed with imperial sizing wax; they shot well, however the powder would stick in the neck and I wasted a lot of time tamping it down.
So anyway, the test was completely unscientific and probably not accurate shooter worthy but the results were pretty clear in 15 rounds with each in a dasher.
Sqweeky clean shot smaller then I expected but not as small as I expect.
Dry and lubed with imperial dry lube shot to my expectations.
Brush in and out shot to my expectations.

Since it was a neck tension test day, I had also tested using a mandrel and different bushing sizes using my normal brushed necks(cases were not cleaned except to clean the outside necks with 0000 steel wool).

My findings were a bit surprising to me.
They all shot small except for sqweeky clean. The biggest take away I had from the test was- every single group shot to a different POI. I’m no condition expert but it was pretty obvious.
I guess I learned that there is plenty of ways to skin the proverbial cat but you better make sure all the cases are the same as far as neck tension goes.

I didn’t shoot with a chrony.
Cases were all freshly annealed.
Accuracy expectations- I strive for 1” of vertical.( I don’t always get there)

I don't claim to be a great shooter and really have a hard time dealing with the wind which was hard in from the left. Actual aim point was the left two red squares, I made no corrections and shot for same aim point. Squares are 1 inch.

The wind variable is why I don't like to do testing in windy conditions like when you said "really have a hard time dealing with the wind which was hard in from the left". It leaves me wondering how the wind affected the two different 10 shot groups. I guess that is why when manufactures test they like to do it in a tunnel.
