20-1 or 30-1 I would say. Twenty parts lead to 1 part TIN is 20-1, sometimes it is written as 1-20. 30-1 is 30 parts lead to 1 part tin, hence it is softer. Sometimes you will see a Brinell hardness number, so you would have to look up the corresponding Brinell number to an approx ratio. The charts are easy to find. The lower the number the softer the compound. you DONT want Antimony in any of your trapdoor rounds, too hard. My two cents anyway.

FWIW- I would invest in the equipment to load a good solid round. The Lee loader? Thats the portable bench thing right? I have one for 45ACP, its fun to use in the field but not to make a good accurate round. Correct me if I am wrong.
