[QUOTE="Swamplord, post: 2340505, member: 2460"] and ya, we all know that longer freebore/seating depth gains a bit of capacity, a bunch of guys here have done that since this forum was established, I've done that with multiple cases and have never seen more than 2 gr improvement in capacity and little velocity increase, unless you combine that with enlarging the top of case body and pushing the shoulder up for a shorter neck, THEN you will gain 5-10 gr capacity improvement, depending on the taper & neck length of the parent case. the 300 Win Mag IS already improved in that manner over the 264, 7mm & 338 mags, along with a longer case length which helps it gain the capacity, kind of like the 300 Wby uses length to gain precious fuel space over the 300 Win Mag simply shoving bullet out without any other improvements and claiming superiority is ridiculous and you need to be aware of the crew here on this forum who are very well versed in such things .... did this one about 6-7 years ago ...with all the Imps, I got to 111 gr h20 capacity, a solid increase over the parent 300 Norma a handful of us here expirimented with this years ago & now everybody is doing it ... sadly the 300 NM Imp has become a "manbun" cartridge, lol ...
