.260 Neck Bushing Size Question

[Joe C]

Hello,

I am placing a big Redding order tomorrow and am trying to figure out what size neck bushing to order for my .260 Remington.

Best I can figure is the new Remington brass I have here has a neck thickness of .015". When I times that by 2 and add it to .264" I come up with .294". According to the Redding directions I should then subtract .002" to obtain the size of bushing I will need. This would leave me with a .292" bushing.

Am I doing this correctly? Is this the size those of you that shoot .260 use as well? Should I order a .291" and .293" bushing also?

Any help from those of you experienced with all this would be GREATLY appreciated.

Also, should I order the TiN coated bushings or just the standard steel ones?

Much thanks in advance!

if your loaded round is .294 then get a ,,"Wilson" brand,, .291".....the Redding bushings are not always "as marked"....its a crap shoot....they are usually much smaller than marked....they wear good ,,work good...but are small....Roger

I rarely get it right on the first try. That's why I have a selection of bushing for each caliber. I have .298-.291 in 6.5mm.

I use slightly neck turned Remington 260 Rem brass. First pass bushing is .292 and second pass is .288. My largest diameter loaded rounds are just on the .290 mark. Nominally my necks are 14 -15 thou thick, but I didn't make a good job of turning them. If memory serves me correctly, they were nominally 16 thou before I scarred them with the neck turner.

I have a set of 7 bushings .287 - .293 to cover off all eventualities. My fired necks measure ~ .296.

I also find a wide variation in weight, from 158.9 gr to 164 gr. If I find a case over 164 gr, I just bin it. I sort them into 1 gr ranges. I am now getting these cases annealed (after 4 firings) and some have reached their eighth firing. I am probably going to select a batch of the 8 times fired and get them annealed again to see how far I can get with them.

Joe,

My .260 Rem. Lapua brass measured very close to .015" neck thickness when new. I skimmed the necks to .0145" just to true them up. I have bushings for my Wilson dies from .292" to .290". On my first 2 sizings and firings, seating tension felt good with the .292" bushing. On subsequent loadings, I went with the .291" as the necks seemed to spring back a little after sizing and I made the change. I did not anneal the cases on the first 4 loadings and am curious what bushing will "feel right" after I do anneal them.

My point is, having bushings in several sizes will give you the flexibility to adapt and experiment. Your math is correct and I think you are heading in the right direction. If you buy bushings from .293" to .290", you'll cover your bases nicely.

Good luck and keep us updated with your project.
