I've only loaded a few 5-round sets to test powder charge weights, but so far this is where I'm at with the 172 grain in my .308WIN with 22" barrel
Impact 172gr.
cfe-223 @ 47gr.
ADI brass, full-length resized/once-fired
CCI 200 primer
coal @ 2.810
avg. vel. 2750 (per magneto speed @ 1100'...
I would suggest some decoys. It'll give the Tom something to focus on visually. Simplicity says 1/4 strut jake and a lay down hen. Position the jake behind the hen a few steps so the Tom gets upset at the interloper.
For calling, figure out how to do a simple 3-note yelp, a little lower pitch...
The website mentions cartridge changes with barrel/bolt head swap. Also the photos look like AR-15 barrel extension set up, though details in written words are scant other than that.
Looks great.
I notice that your SOLO 300 appears to be a more traditional M4 upper with the required bolt handle slot. Interesting that the design has changed. I wonder what the weight is vs. the original billet-style weight.
My go-to rifle is set up with an AICS system. The 3-round MDT mag is darn near flush and carries very well. Despite the large release lever, I've not had an accidental drop scenario.
I've never tried an owl hoot call, but I was feeling my oats hunting with my son one beautiful morning, and figured the Hunting Public guys made it look so easy with just their mouths that I let loose a wail. To this day I still couldn't say what the heck kind of noise burst forth from my mouth...
