A couple of things...
First I load with a 650, and I find I have poor results with some brass, mostly cheap imported range pick ups. I have best results with Winchester.
Second, be sure you are crimping ALOT. Check with a micrometer if you have one. You don't want the mouth to be the largest part of the round. Also, get a loaded round gage from Dillon. They are cheap and a good check of your loads. (Helpful to find a problem BEFORE you load 5,000 rounds.)
Third, No I haven't found Colt's chambers to be particularly tight. If I get a load that balks in my match Briley bbl, it will usually drop right in my dad's Gold Cup.
