Is there a easy method of polishing those case necks to achieve a more uniform tension? r in s.

Most Benchrest shooters use a bristle brush either by hand or with a power source such as an electric drill. Use a brush that's oversize for the caliber. I make it a habit to brush the necks as the last step before dumping powder and seating the bullet, especially if the cases are not going to be loaded for a long time.

Ray, i use a rcbs prep case machine with a brush in one of the stations. I wrap the brush with steel wool and after the inside chanfer i will polish the inside neck. it removes any burrs and case neck tension is always consistent, Dave

for the RCBS case prep machine with a bore brush twirling round and round. Great medicine for dirty necks.

That's OK, but you can't take the machine to the range.

Good point butchlambert. That is why I have ammo cans of prepped brass I keep around.
I used to load at the range. But now prefer to spend my range time shooting.

P.S. You can take the "machine " to the range. All you need is a power inverter hooked up to your car's electrical system.

I use these on my BMG reloads... If it works for top Fuel and NASCAR, it's got to be good enough for me. About a second in and out leaves a very nice, immaculate crosshatch



www.mcmaster.com look for "ball hone" from 4mm to 16" (for your big gun)

Collins doesn't that hone remove metal? I would think you could only use it once or twice without thinning your neck. Just thinking out loud.

Said hone is used to texture the cylinder walls so they retain oil.

I'll run it through a couple of times and see if I can measure any metal removed. I normally run it in and out twice and it's got a very nice and very uniform finish. There are different grits, I run the finest. Like SR4759 said, these hones are used for finish work on cylinder bores they won't fix an "out-of-round" condition. It's generally the last thing I do before the primer, powder, bullet.
