Not necessarily... He could just have a chamber that is very near to the minimum spec. Some factory ammo is a bit more generous.
I have a British-made .30-'06 that will not close on Remington made ammo; but works great with Federal stuff.
7mm rmag being finicky, help!

Regardless..if it is the chambering, I sure the hell wouldn't want to deal with it, get it recut and be done...or it could have to do with something else.
Factory ammo should feed with no problem and thats a fact.
I'm guessing tight chamber or seating die screwed down too far. Measure the cases, are the ones that fit shorter? Measure OAL, here's a couple of methods but I like Hornady's bullet comparator best. Any deviations?

Just went through this today on a different caliber.
Had four that wouldn't chamber in either two 308's win we have here.
On real close inspection, I found a slight bulge where the neck meets the case.
Just enough to catch.
Hard to see but once spotted, gave me the reason why they wouldn't let the bolt close.
Cure, seater die too low.
Why only these four out of the hundred or so, I just don't know??
I could feel the lump with my fingers, fondled them so to speak.
Did you roll the resized empty cases on a flat top to check to see if the necks are running true?
One set of dies I had for some reason pulled the case neck off to one side.
Not sure if this would cause your problem though.
Just a thought.
Keep us posted.

Hey guys, thanks again for all the suggestions, basically i dont think i made the first couple posts clear enough. in a pack of 20 winchester from the factory brass, i was unable to put 3-5 cases through per pack. I have 5 different packs of ammo and same results in all factory ammo, not loaded, not sized, all factory.
The cases OALs and such was up top, no deviation over OAL from ones that chamber to ones that dont. With that scraping on the head of the brass that i discovered from a previously fired cartridge though, i do believe its smith time. when factory ammo doesnt work, reloaded full length doesnt work and even fired cartridges only fit hit and miss...
will let you know by the end of the week.
my thoughts at this time are a strange or jammed extractor? something to do with the head engagement on the bolt face

I found it pretty clear..just trying please everyone..lol
try throwing a shortened version in the gunsmithing forum..might come up with something there..
Its called a mitch kendal custom, as far as i know he did lightweight hunting barrels for the heavier calibers. As far as how the barrels came, custom, he milled them or otherwise, i really dont know, this is a 3rd party gun i think since him. The only brass i am using has already been shot in the gun, by me a few days ago. This also makes me scratch my head
Mick McPhee most likely did the chambering and put the gun together for Mitch. Mitch does inletting etc but not barrel chambering/contouring to my knowledge.
Its a long shot, but since everyone else has covered the sizeing and bullet seating angles, I'll try a different approach. Sometimes the extractor doesn't want to jump the rim, due to crud or sand underneath the extractor. Rim variations will let some go by, and factory sized cased are small enough to have a little extra wiggle room for the extractor to get by. I've seen it on brand new guns too.
Its an easy check. Take one of the cases that won't chamber and slip it behind the extractor before trying to close the bolt.
That extractor is a weak point of the Remington design. Not so much because they break, because they aren't any worse than anything else in this regard. The downside is one lousy grain of sand can turn your rifle into a clumsy singleshot, or even better a non functional singleshot with a live round sitting in the chamber.
