I wanted to build a short-barreled suppressed 300 WSM for a while. This will be a work in progress. I will be trying a few different suppressors, brass, and powders. The bullet I want to use is the Berger 200x20. I named the project the pug because is short and ugly. HAHA.

Here are the specs at the moment.

Built by Whaley Precision Arms
Ammo by @Unknown Munitions

Bat Bumblebee Action
Carbon Six 20" Sendero Barrel
Manners EH-1
Geissele Super 700 2-Stage Trigger
NF Rings
NX8 4-32
Thunder Beast Ultra 5

Tagged in, interested to see if you can solve the powder can build up issues.

@Unknown Munitions
Loaded me up some Berger 200x20 with IMR 7828ssc and VV570. The 570 didn't hit 2600 fps with the max load. The 7828ssc went 2848 with mild pressure signs. I need more rounds and some ten-shot groups to confirm but I think we are off to a good start.

I don't like RL 26. It had very weird temp spikes for me. I will be trying some VV-568 and ADG brass when it comes out.

This three-shot group was 68 grains of 7828ssc, all three shots were 2848. I guess @Unknown Munitions knows how to load bullets:)

Following closely. I dropped off my components for a 20” 300 WSM about a week and a half ago. What particular role/use do you have planned for yours?

Be interested in seeing what you get with some faster burning powders. Those fast powders and some lighter weight higher BC copper bullets would be a fast setup.


Why the WSM and not the 7 SUAM?

What twist rate did you choose for your barrel?

Nice setup I love having a supressed shorty for timber to 600 yard shots.
When you burn it out get serious and go 16", run a 9" suppressor and smile in amazement at the nail gun pop

That’s hideous! Take off the scope and can, I’ll send you payment and my FFL info to get rid of it for you 🤷‍♂️

How do you like the nx8? I have a 300wsm being built by hells canyon, and I've had my eye on that scope.
