.300 RUM muzzle brake suggestions

[Boatninja]

As title suggests, does anyone have suggestions?
A friend brought me an older Sendero 300 RUM and asked if I could get it sighted in and shooting right. I asked what exactly was it doing , he said nothing exactly, nobody has ever shot it more than 2 rounds! I said welll, let's see if we can find the mother of all muzzle brakes!

Sort of partial to Cadex MX1. Might be a lot of brake.

Brother In Law has a BDL .300 Ultra. With a Decelerator recoil pad, I didn’t find recoil terrible. I think he runs 180 Accubonds around 3200 (granted, I was 10 years younger the last time I shot it). The Sendero should provide more weight.
With a good recoil pad, I don’t think it’ll be all that objectionable to a reasonably experienced shooter. At least for sighting in and shooting a few rounds at a time.
I’d shoot it before I put a brake on it, as I’ve gotten to where I simply hate a brake.
