A couple two word phrases come to mind. Slower bullet, is the first one.
If you are not facing long distance shots, load lighter.
How close to a max load is the 49gr of 748? Velocity? Fast bullets at close range equals lots of bloodshot meat. Esp. when smacked into the front leg/shoulder area.
Did a quick look around the web and came up with info that showed a 47gr +/-load as max, with velocities in the 3000 foot range. No bloody wonder.
Take a good look at the velocities that the factory loads are loaded to. Even they are pretty fast for close in work like you are doing.
Bigger bullet moving slower, same bullet moving slower, or bullet designed for dangerous game (heavy jacket) and live with poor expansion at longer ranges. I suspect the selection of light bullets with heavy jackets is slim pickings.
Or start picking your shots better to avoid meat loss (rib cage, a little farther back to clear the front legs, from broadside, makes a right mess inside, but does not leave the front all full of blood, for example).
Under ideal circumstances, I like to aim just back from the point of the 'elbow' or a wee bit above that.
A bud of mine smacked a WT doe on the shoulder with a 300 Win. Mag. at 20 yards. What a mess.
