I know of an old guy who bought a Past Shoulder pad over 40 years ago for shooting off the bench and has shot hundreds of those thumpers with it. Especially having fun testing 12ga turkey loads and various deer slugs. His 300WSM too. He still uses it, even shooting light recoilers. Caldwell sells them these days.

They are similar but slightly different. A Past and .358 Win speeds off the bench might be a good compromise. You'd never know the difference between 35 Rem and 358Win shooting at game and the 358Win velocity would reach out to 200 just fine. Beginning Whelen loads might be OK.

BE STRONG IN THE LORD, AND IN HIS MIGHTY POWER. ~ Ephesians 6:10

Socialism is a philosophy of failure,
the creed of ignorance,
and the gospel of envy,
its inherent virtue is the equal sharing of misery.
--Winston Churchill
