I found the Otis kit great for range work with students, dealing with different platforms and calibers...even shotguns. I dealt with teaching new shooters and many times just the ladies, for revolvers and lever actions, they like the Otis Works fine for out hunting as well.
I grew up using a similar set up - what was called a "thong" in older military jargon. Basically a length of rawhide kept in a shoe can tin with patches and oil, still do. What one did to hold them until they got back in to camp, or home.
I like Pro-shot one pc rods. I like their brushes , bore guides and such.
I have been using some one pc rods from Ox-Yoke while shooting and visiting with an old friend. Quality at a good price.
I'm not a benchrest shooter, don't shoot a lot of rifles, so I bow to bogie and those that do.
I concur NO STAINLESS BRUSHES.
ONLY thing I have found a stainless brush good for ( besides gunsmiths' retirement fund) :
Take that aluminum rod and put a stainless brush on it, cut the rod so when chucked in a battery drill you can reach the weeds without having to stoop over. Insert into midst of weed, push down and hit the drill's trigger....that weed will be pulled up and cause you no more problems.
If you cut off the first few spirals of brush , gives you a more pointed insertion tip...Life's too short to pull weeds, cuts into shooting time.
