nosler custom ammo in 35 whelen

[hofts]

i wonder what their recipe is for these, as the 225 gr partitions, and ballistic tips are 2750 fps at the muzzle, this is around 200 fps faster than anything in their #5 manual! i ain'nt complainin, i like it, i'm just curious how they got it.!
i have some but i have not tried it yet.
all over the counter 35 whelen is very mild i do know this, big time difference between those and my handloads which i think are around 2500 fps whatever is in the nosler manual.
