I've got a Remington 700, in a 300 RUM. I'm shooting Hornady's 165 grn Interbond with Retumbo powder. I usually have to clean it after about 17 - 20 firings because the groups start to spread out. I've got a couple of other rifles that don't need cleaned anywhere near that often to maintain their accuracy. Does the above seem unusual?

got a 700 in 300RUM myself. cleaned it a week or so ago, but couldnt tell you how many rounds went thru it before the last cleaning. 100+ at least. there for a while i was afraid to clean it, because the more i shot it, the more groups were sticking right with each other. didnt want to try and fix what wasnt broken.

Could the groups have started to open up because the factory barrel was to "hot" after a few rounds?

This will make the groups open up considerably.

If you shoot 4 or 5 for sighters and then 5 more rounds for group in a factory barrel, the 300 RUM is producing quite a bit of heat in the hot summertime temps.

Don't know how much time had elapsed during you 17 to 20 shot string?

Just a thought.

I try to keep mine clean inside of 30, but have gone as high as 70, that in 223, before cleaning, and after proper barrel breakin.
