Model 10 ?

[goob]

I have a model 10 in .243 and if I goto a 6, 6.5 or 7mmbr how well will they cycle in the magizine.

Well, it depends....
I changed a 25-06 to 22-250, and all was fine. I did a 243 to 223, and it hicuped occasionally.
I haven't personally done the cases you listed, but I found that Savage's followers aren't the best for consistency anywho. So a little tweeking, or replacement may be in order.
