the suggested max cartridge length is 3.340

the max length my magezine will hold is 3.360 and at this length i am not touching the lands

my question is has anybody here loaded over the 3.340 and if so did you have any problems

? bullets jamming while loading?
? recoil problems on bullets in magezine?
? am i missing something else?

if needed Browning A-bolt .300 WM - 72.1 gr. rl 22 - 180 gr. accubond - cci 250 Lr mag primers -
