.270 bore brush in 6.5x55 (.264)?

[mosinmaster]

Can I clean my 6.5x55 (.264) rifle using a .270 bore brush? Would it be too big? I can't seem to find a .264 bore brush.

It will work just fine. that 0.3mm won't make a difference in a brush.

I use one in my .260 no problem.

How about if you are using a bore rod and cleaning piece. Would a 243 be too small and a 270 too big. I just picked up a 6.5x55 and would like to run some jb bore paste. I would hate to get it stuck.
