I also have a Shadow 2 and up until now have been shooting factory ammo. I recently bought a press and looking into reloading.
I was advised to use ADI APS 70 or the APS650 whenever it comes out. i am trouble getting both.
Is anyone experiencing issues with getting powder atm ?

Covid-19, Civil unrest and 'defund police' demands making people want to own a firearm for self protection so millions of new first time firearm owners all wanting ammo
After 6-12 months the shortages will spread to the rest of the world, it will likely get quite bad here too.
Some US manufacturers already have an 18 month lag for meeting any new orders and that's increasing daily.

I have done up some light target loads, as low as 3.3gr with 450 and never seen any tumbling or issues cycling.

New reloader here.
I have hawwkesbury 115 gr conical projectiles using APS450N. According to the ADI spec sheet , max on those projectiles should be 3.5 grain for a 1018 fps travel.
This puts me in a PF of 117. A little below what's need for Service (120) .
Can I safely up the load to say 4.0 or even more ? I'm also shooting with a Shadow 2.
btw, Min load is 2.7 . Im thinking loading 10 rounds of 2.7, 10 of 2.9, 10 of 3,1 , 10 of 3.3 , 10 of 3,5 and so on until I reach 4.0 . to work out the sweet spot.
Is this a sane strategy?

My personal experience says yes. I've done the same with my own experimentation and have gone up to 4.2 from 3.5 in 0.1 increments.
At 4.0gn APS450 with a 125gn projectile I'm getting around 140pf. My OAL is 1.130".
You'll need to work slowly looking for signs of overpressure. Things like flattened primers etc.
What your planning is sane. Just check and make small adjustments when changing grains to avoid a bigger boom than you want.
Macross wrote:I followed a guide to work out my max AOL and then just come back from there. Basiclly, take a fired case that you can get a projectile in without flaring and crimping. It should be albe to slide in and out a bit. Take your barrel, and gently slide the round into the chamber, pushing or seating the bullet as you go. Once you push it all the way down, gently take the round out and measure the AOL without pushing the projectile in any deeper. This is the longest you can seat rounds whilst not letting the projectile sit on the lands.
You should be able to drop a finished round into your barrel and freely turn it without it binding.... if its jaming up then the projectile is seated too high and is contacting the lands.
