Let's see here. My 90s measure .440 and .841.
My OAL measured with comparator is 2.310.
Those 130gr Partitions loaded to same comparator measurement would be 2.840 "true" OAL.
The others are about the same, distance from ogive to tip of your 4 is .530, .547, .556 and .541
So, the longest I could get with the same distance from rifling (.004) would be 2.866, so only .166 over book length.
That's the shortest free bore I've seen in a rifle, not that I've seen a lot. Even my .204 can be loaded that far over.
Still happily answering to the call-sign Peetza.
The problem, as you so eloquently put it, is choice.
He is no fool who gives what he can not keep to gain what he can not lose.
