Since my Creedmoor is a 257 Roberts, I can’t speek for the 6.5, but I just tried small primers in the Roberts and they keep falling out...
Maybe if you “REALLY” cram them in thier they will expand enough to hold
BTW - one of the only times I disagreed with MD... is when he said to think of the Creed as an “improvement” for the 260 (my 257 Roberts)...
It’s an improvement for a competition gun, but my 260 is my 300 and under hunting rifle... so it’s not too much “improved there”
Post edit - for those that didn’t pick up on it - I had to try really really hard to find something to disagree with MD on with the improvements the Creed has (otherwise I wouldn’t be building a 6 creed right now)... i.e. - my arguement is kind of BS.. Energey is Energy (my comparison)... yank’n MD’s chain a bit...
Personally I did love hating the creed... but it does have a bunch of benefits one should not ignore just because it’s fun to do so.
I’ll have to see if those small primers are loose in my 260 as well....
