Merry Christmas from MDWS 🎄

Keeping with the 6mm Mongoose theme, our December Mad Dog of the month is Andy C. From coyotes to massive hogs, his mongoose shooting 80gr GMX is a hammer!

12/15/2022

We are reintroducing some of our cartridges for the new followers. Today, we are going to cover the cartridge.

Cartridge overall length 2.26"
Max case length 1.700"
Trim to case length 1.690"
On loaded rounds, the neck needs to be under 0.268"
Bullet range 55 grain to 107 grain

The 6mm Mongoose is a wildcat round based on the .223/5.56 case. It uses standard magazines and can run bullets from 55 grains up to 95 grain; the 105 grain AMax will work at 2.29" COAL, but the heavy "VLD" bullets won't fit. The shoulder is 40 degrees and the case taper is blown out for increased case capacity, so it does require fire forming to reach its ultimate potential.

Making 6mm Mongoose brass consists of running through the die which pushes the shoulder back and then trimming to 1.690-1.695" (the rounds will shrink a little on the first fire as they stretch to fit the chamber). That is it - load them up and shoot to fire-form the case.

For load data, you can start with 6x45mm data. A good starting point is 1 grain under max loads for the 6x45 and work up. Max loads for the Mongoose will be above that of the 6x45 due to the Mongoose's larger case capacity once fire-formed..

Here are some velocities that can be expected

18 inch barrel
80 gr Federal pulls 2900-2990 fps
68 gr Match Burner 3100-3200

20 inch barrel
87 gr V-Max 2750-2880
90 gr FMJ 2750-2800
105 gr A-Max 2500-2600

22 inch barrel
55 gr Nosler tipped Varmegeddon 3300-3500
90 gr Nosler AccuBond 2700-2800

Our very first Mad Dog is Derrek Ochs with his 25gpc 20” barrel, Savage 110 tactical action in a MDT xrs chassis finished off with a ACC 7.62sd suppressor.

Thank you for your support!

ATTENTION! Just like everyone else, we are sad to announce we will be raising our prices November 1, 2022. We held out as long as we could but with the way things are these days, our costs are through the roof and we have no choice. HOWEVER, we put everything "On Sale" for our current prices until November 1st. So, if you were on the fence, grab it now. Wolverine, Mongoose, 24, 25 and 27 GPC all in stock... take a visit and see what you'll be saving by buying before November 1. Sorry all, we had no choice if we want to stay in business.

Good afternoon! We are looking for MDWS wildcat cartridge content. If you don’t mind sharing, feel free to message us pictures and/or video with a brief description.
