I had an extra 452460 Lyman 200 mold and had the ugly one cut out to a 245 grain but the bullet is the same ol length. 200 on the left and 245 on the right. This mold drops a 454 bullet so it is perfect for a 45 Long Colt and it works in a 1911 also but I have to size it .452 for that. If I had your Wilson it would only see 200 grain lead H&G 200's.
