Something to keep in mind
I thought I would share this with you guys. Several years ago when I bought my first T3 I was working up a load with IMR 4350 and 110 accubonds and as I was doing so I was starting low working up slowly just like always watching for pressure signs. Well I never got any pressure signs other than high velocity. no sticky bolt, no ejector marks on the case head primers were perfect. Velocity never spiked, just continued to increase at a very even rate. Finaly at about 3250 I started to get some signs, so I backed off half a grain and thought I had me load as accuracy was great. When I went to reload my brass my primer pockets were all loose.. not kind of loose but very loose, Dangerously loose. I thought maybe I had a bad lot of brass so I bought more and the same thing.. I dont know what caused this but Here is my theory. Its possible that my chamber was cut so evenly and the finish was so smooth that ejecting a piece of brass was easy even if it had been over pressured. and Primer flow I cant explain other than the firing pin in relation to the firing pin hole was perfect and would not allow primer flow… this is all theory but knowing the quality of these rifles I think its highly plausible that in some cases its harder to spot pressure signs because of the super smooth finish and the tight tolerances of these rifles.
