Sherman Mega Line
Meet the Mega
With the mid length action market on the rise, I decided to design a case which is destined to become top dog and called it the MEGA! Think of it as a long WSM that has been "Shermanized" with the efficient, low body taper, 40 degree shoulder, long neck design that leads the industry. Offerings will be available in 7mm, 300, and 338 bore sizes.
PERFORMANCE
This case will rival much larger cases and do it in an under 3.2” COAL (3.3” Free Bore option for longer actions).
Approximate maximum performance will be as follows:
7mm @ 3200’/180s and 3100’/195s
300 @ 3075’/215s
338 @ 2950/250s
BRASS
Top quality ADG head stamped brass will be available in 7mm and 300 head stamps. All brass will come with a 300 neck and require fire forming to a 40 degree shoulder from 35.
DIES
Hornady custom Match bushing die sets will be available as well as a top quality pr- pay option from Bullet Central (Micron)
I expect the 7mm and 300 versions to become top contenders in F class, 1000 yard, and some ELR competitions, as well as very potent hunting options. The 338 version will offer compact bear stopping performance normally only found in long action magnums using much more powder.
Here is one example of why the MEGA should really shine. The 300 WSM has won many 1000 yard competitions, so here is a spec comparison:
300 WSM
case length 2.10”
capacity 81 grains
neck length .298”
*max velocity 3000’
300 MEGA
case length 2.16”
capacity 85 grains
neck length .342”
*max velocity 3075’ (3000’/H1000)
*26” barrel
The Sherman Mega family of cartridges includes the 7 Mega, 300 Mega and 338 Mega.

Introducing - 375 Yukon
The all new 375 Yukon is a departure from most of my designs, but fills a very important niche, IMO.
The Yukon is a modified version of my very popular MEGA line. It is designed to take
advantage of modern high performance monolithic bullets for big killing power on large and dangerous game and allows for building on short, light, quick handling rifles, even in a short action!
My two test rifles were, in fact, a 700 Remington short action and a bone stock Tikka. The 700 has a 17 1/2” barrel and will run a 270 Shock Hammer at 2712 and 2.960 coal. TRY THAT in your H&H! The Tikka has an 18 1/2” barrel and runs a 248 Hammer Hunter north of 2900’. There is plenty of free bore to run much longer and heavier bullets in the Tikka length magazines. My 700 weighs in field ready at 7.8 lbs with a #5 barrel and 3 port brake and equipped with a 4.5=14x50 Leopold scope. OAL is 38 1/2. The bone stock Tikka with a #4 barrel and same brake and scope weighs 7.2 lbs. Both rifles are well balanced quick handling packages with a LOT of authority!
So far 2 bears, one elk and a deer have been taken and ALL DRT. The black bear taken in Alaska was facing head on at 260 yards and took a 248 Hammer Hunter in the front of the chest and exited his after burner! Everything in between was trashed! My bear and elk were taken with broadside heart shots at 250 yards and DRT! With something like a 275 Badlands Bulldozer, this package becomes an easy point blank to an over 800 yard rifles. Hard to beat that in Brown bear/Caribou country to African plains game.
Reamers, dies, and brass will be in stock and a couple smiths will have a longer free bore reamer for 350 grain bullets for the largest African dangerous game.
300 Mega Brass will need to be necked up and fire-formed
