Thread: 1-10 twist 7mm mag

Does anyone have any experience with a 7mm rem mag with a 1-10 twist.
I’m helping set one up. Will be used as a 0-600ish gun. Kinda a general purpose gun.

Anyone have first hand experience how heavy a projectile I can use for him.
Looked the the 162 ELDX but has a min twist of 1-9.5
The 150 ELDX has min twist of 1-10, so thinking of that.

So any thought or opinions
Cheers
