.338 shooters, cleaning rods?

[338LM]

I have been using a Dewey .277-.338 rod on my .338.
Has anyone tried to use a .35 caliber and up rod in a .338? I measured a Bore Tech rod today and the coated shaft was .315 and the brass ferrule was .310. I assume that a Dewey rod is approx. the same sizes. Do you think .023 is enough clearance for patches? I clean with patches only with push thru and wrap-around jags. I do not use brushes.

I use a bore-tech rod in my lapua, so that one may work. You might have to experiment with correct patch size for that combination.
