RL 33 works great in the RUM. sure it would work in your case too and it's pretty available. Don't know what you would start with since I don't know what your free bore is and how long your gonna set the 230 out.
Is agree with Dosh. Check out Broz's posts and you'll be sure to find a great load or a good start anyway. Just shot mine this morning which is a stock Accumark. 94 grains of H1000 with a 215 primer. Consistent 1/2 to 5/8 groups at 100 yards. Of course with some barrel cooling time. Broz is spot on with his advice. It saved me a lot of time working up a load. Good shooting.
