[QUOTE="Fiftydriver, post: 1885424, member: 10"] it is true that the edge and lapua have nearly identical case capacities but the lapua will support dramatically higher chamber pressures then any RUM case. The standard 338 lapua compared to the 338 Edgem when both are loaded to SAME CASE LIFE LEVELS, the lapua will add 100 fps to the Edge. people then applied the ackley improved design to the lapua and started getting extraction issues, especially when brass got older. The ack improved design was ment for 06 diameter cases, never large diameter, high pressure cases. My design offers max capacity, proper case body taper to get the max performance out of the lapua parent case. Its not unusual to see 200 fps advantage over the Edge.... or looked at it another way, my 338 Allen Xpress will do in a 26 in barrel with short 3.670” oal ammo what a 338 edge will do in a 30” barrel with extremely long, single shot only ammo length and needing special throats to get it. in my professional opinion, 3200 fps our of any Edge is laughable and over the years, those claiming these velocity levels have all pretty much settled back to sub 3000 fps levels in extremely long barrels for some reason, generally they claim the rifles just shoot the best there. this surprises me as my rifles pretty much shoot the same at 2700 fps as they do at +3000 fps so i suspect the real reason for the throttle back is likely for other reasons. Its also been discovered that when they were promoting these numbers they were getting VERY SHORT case life, at times only one or two firings.... again, nothings free. [/QUOTE]
