Any reason you think your load would be different for brass that's been fired?

Not necessarily, it's just overkill and a waste of powder. You'll either blow the bullet outright or it'll fragment explosively because you impact with too much velocity.

I shoot 110gr V-Maxes in my 300WM for coyotes simply because I haven't put together a .243AI yet specifically for that purpose. THey shoot 3800fps, you could get them over 4000 out of your RUM. THey are accurate as all get-out.

The lighter bullets will also burn your barrel faster, which is why I don't shoot them much in my 300.

There has never been one case of a bullet blowing up out of the barrel.

Proof?

"If you spin your bullets too fast, this heats up the jackets and also increases the centrifugal force acting on the jacket, pulling it outward. The combination of heat, friction, and centrifugal force can cause jacket failure and bullet “blow-ups” if you spin your bullets too fast."



Push light bullets too fast in a barrel with a fast twist for heavy bullets (ie many magnum rifles), and you'll see it. Especially since light bullets are often thin-jacketed varmint designs. They can't hold the RPMs.

You can get bullet skid, but thats not a blow up. Total BS myth.

Gotta agree on the 168gr TSX in the RUM. My go to load is clocking right at 3370fps out of my RUM and I pushed three of these thru a moose this fall. Penetration was very impressive, one went stem to stern on my bull. Talking over 5 feet of penetration, entrence in right ham, exit out front of chest on left side, Also placed one at a hard quarting angle thru the pounch and out the far shoulder right at the shoulder ball. actually pushed grass out of the exit wound. Range was about 180 yards.

I could push that bullet faster but have found excellent accuracy with this load, sub .5" groups with reasonably consistancy and always under an inch. 300 yard groups averaging around 1.5". Thats about as good as I can do with any rifle.
