I have been shooting the 300 Elite Hunters out of my 338 DCM at over 3400 fps without any issues.
They appear to have the same speed & ballistics of the 300 OTM
I have shot them past 2000 yards with no problems of them "disappearing" even out of a warm/hot barrel.
Also havent had any trouble with them shooting rocks past 12-1400 yards.
I sectioned some projectiles in December last year to roughly find out for myself the jacket thickness.
Gen 1, 22 thou.
Elite Hunter, 25 thou.
OTM, 29 thou.
SMK, 23 thou.
I use a 1-10 36" Lilja barrel.
