I have a Weatherby vanguard, not sure if they are known to be tighter than other chambers. I thought standards were made so things were made the same.

That's why you should Full Length resize any brass you use of unknown origin so they are within SAAMI Cartridge specs. and then probably try chambering in the intended rifle before carrying on with reloading process. Not all reamers of the same caliber are the same, even from the same manufacturer. They are all made to fall within manufacturing tolerance specs., so variation can and does occur with chambers. Just my 2c.
