You could go 7Rum if you have the length, stick with the BM is easiest

I have Whidden dies in stock & 46 bits of new 7BM brass in stock

Or 28 Nosler. Base is 0.550 vs 0.545 for 7BM. I wondered about wild cat the 28N or 7RUM down to COL size of 7BM but it would retain the 28N base of 0.550. The chamber would need to be teamed to fit the larger 0.550 base. You’d end up with a 7BM with slightly increased capacity. Quite a lot of pfafging around but doable.
