I have an Axiom U/L on a Weatherby Vanguard in 300 wsm
. I am shooting factory Federal 180 TSX. One day, I put 60 rounds down range in the prone with a t-shirt on and didn't feel a thing. Also, no bruising. I did replace the factory recoil pad with a Limbsaver pre-fit. Can't remember model number. If you get one just take your adjustable stock off and find the model that fits. The mount holes will lign up perfect. The pad will be a little long at the top end(1/8") and about 1\4" short on the bottom end. Fit is still pretty good. The only thing I would suggest is a pad on the cheek. After 60 rounds, the muzzle jump was more noticeable than the recoil. I have my cheek piece in the upper position with tall mounts for the scope. I heard a couple guys say the scope is too close on the U/L model. Hello...the stocks is adjustable. Make sure you adjust your stock length(according to your trigger pull and comfort) before mounting the scope. Also, remember that this unit compresses slightly to take away felt recoil. Maximize your scopes eye-relief. I have shot 600+ rounds without contact. My scope only zooms to 10x and has a 3.4 inch eye-relief.
Here's a link so you can see what I'm talking about. Hit the zoom to get a better view.

I wanted a cheap tack driver, and hunting back-up rifle, that I could shoot more without developing bad habits. I have a Browning 300 win mag w/boss-cr that is my primary hunting rifle. No brakes for me anymore. Tinnitus in my left ear. Anyway, I only way about 150 and the magnums beat me up a little. Not with the Axiom.
I am getting consistent 1/2-3/4 inch groups with this rig. I am just starting to reload and expect this group to get even tighter. I did have one advantage though. When I bought this rifle, I had the guy behind the counter grab all 4 300 wsm's and show me the target from the factory. This gun was sub-moa before Weatherby started the Vanguard Sub-Moa line. Today's cost around $700. My cost a couple years ago was $425.
I also installed a Axiom Comp-Stock on a friends Remington 300 Rum Sendaro with a limbsaver grind-to-fit. He also had a brake on the rifle. I can't vouch for the recoil without the brake, but, the combination of all 3 add-ons turned his gun into a puppy dog. Perfect for him since he's 65 with a bum shoulder.
My conclusion. If you're not a fan of recoil...buy it. Just remember. You might have to do a little bedding around the pillars to make it more accurate. Mostly in the U/L models. After bedding my front pillar(only a 2inch section) the action is very snug. I have to pull with some force to get it to release. I didn't do any bedding on my buddies Comp-Stock and his rifle was shooting sub-moa also. Hope this helps some of you interested in the Axioms.
