    So due to the reduction in land profile directly in front of the projectile, it probably is going to allow reduced pressure because of the progressive nature of the engagement, but there is also less land material to resist premature wear?

    Hell look at the publication date. It's been public knowledge for a year. Anyone who claims to have invented anything similar since then is nothing more than copy cat.

    As I hinted at the other day, plot pressure and distance over time on the same axis and you will see interesting things.

    There is little in this world that can't be explained by science/physics..
    Everything has laws of physics to blame.. im not claiming to be einstein but i can see basic physics in everything we do!!!
    Sort of like why cases such as WSMs get much better speeds than say a 30/06 based case with F-all extra capacity... more surface area for pressure to build/disperse I suppose!

    Yes on the 1st part-exactly
    uncertainty on the 2nd
    A large number of rounds would be the only certainly.
    And what do you compare it to? Std or same performance ?

    And this is where we may disagree..
    A 30.06 and 300 WSM run different pressures so no apples and apples.
    Wsm at 06 pressure would result in 06 speeds IMO

    Well there is less land material to resist wear.... I should have said would it wear at the same rate given the same loads being used.... and to that I guess we don't know... if the pressure was reduced it may not I suppose

    you're probably not looking for an increase in fps with those..

    But thats exactly what i mean spanners.. the extra case capacity of the WSM is fook all over a 06 what 5gns?? but you can run much higher pressure and speed!! Due id say to the differing surface area and differing internal dimensions of the chambering to allow the pressure to be disposed of... so we do agree!!!

    But ur well right apple with bananas!

    How well does the 168 Amax go expansion wise subsonic?

    You might want to consider the date of conception of both those rounds before making such rash statements.

    No your not gettn it what i meant.. time of conception or so called pressure ratings i dont give a fuck... ive loaded 2506 6.506 .270 & 3006... 6.5wsm .270wsm & 300wsm!!!! I was talking about performance relitive! not performance ralated to a friggin outdated action!!!!
    IM TALKING BOUT RELITIVE PERFORMANCE BETWEEN THE TWO CHAMBERINGS TO EMPHISIS WHAT SPANNERS SAID ABOUT PHYSICS AND SCIENCE!!!!

    All you guys need a go get spelling lessons!!! EVERYTHING HAS TO BE SPELT OUT FOR YOU ALL LIKE kindergarten babies!!!!!!!!!!!

    Look at this thread for example an entire thread of kids running round in a daze like babies goin duh what!!! Oh it was spelt out for me!!!! Duh oh i didnt read it properly duh naaaa i still dnt get it duh!!!!

    You all wudnt even begin to understand what alot of this thread stands for lol....

    Bro are drunk?

    Talk about throwing rocks in glasshouses. Try a spell checker yourself. We get what you're trying to say but what we are saying is that if you ran your WSM and the '06 at the same pressure there would be bugger all difference in result...

    This thread is great, i've been able to use heaps of mint one liners...
