There's a reason, that the manufacturer's suggest the semi flat point for the tubular magazine, and I wouldn't,
take a chance on having one slam against another, in the tube, possibly causing an accident.
It's just not worth it to me!
I have fired several hundred rounds over the yrs. with the .375, 200 gr. and 250 gr. Ammo,
and never a problem.
So, NO for Me!
