It's probably too late for this advice, but I'd recommend a Jacketed Hollow-Point Boat-Tail (JHPBT or BTHP) without cannelure instead of a Plated Soft-Point with Cannelure (PSPCL). Jacketed bullets typically have a thicker copper jacket than copper plated bullets and will yield a stronger tip. A soft-point bullet has exposed lead that must be removed and may leave a hole that is larger than you want. A small hollow-point gives your drill bit a natural center to follow. A boat-tail (the bullet base tapers) bullet seated deep enough will give the tube something to center against, helping to keep it concentric. A cannelure (the depressed or ridged ring around the bullet) doesn't look quite right if the bullet is seated too far out, which many people do. If it's right at the case mouth, then that's ok.
