Yes, use bismuth shot. I make my own as you see in my Avatar picture, #4 bismuth just dropped from my Oasis shot maker. You can buy the shot from the following places.
Rotometals. Zip Metals, Ballistic Products. Do a type search for those companies.
You can shoot other shot types and I have. But they still require a shot cup. They are, Tungsten Shot, which includes Hevi Shot, Hevi Weight 13, 15, TSS which is heavy weight 18, Nice Shot which is made from a Tungsten slury material which is soft like lead but can be mildly abrasive. I have shot all of these over 20 years and bismuth/tin the best. The bismuth/tin shot we have today is better than it was 20 years ago. Most commercial mixture is 5% to 6% tin mixed in with bismuth. Very close to lead like performance. You need to go up 1 shot size though unless shooting very close. Good shooting.
