The 375 Whelen was developed  by the late, Robert Wallack a gunsmith in 1951 by taking
a 30-06 or 35 Whelen case and necking it up to .375" caliber.
It is very close to the 375 JDJ see differences above and in the picture.
The projectile are 220 grain to 300 grain.
These cartridges for sale, were made from Remington 35 Whelen Cases so the headstamp
will read "35 Whelen".

Although the 375
JDJ & 375 Whelen
are both made from
the 30-06 or 35
Whelen cases, the
375-06 JDJ has a
very short neck
length due to the
60% angle which
helps to increase
case capacity to 77
grains (water) vs.
73 grains (water)
capacity the 375
Whelen Wildcat
holds, which makes
the 375 JDJ ballistics
more then the 375
Whelen.
