My wife and daughter shoot a CVA Squirrel rifle and a TC Seneca. The CVA Squirrel rifle is a .32 and the TC Seneca is a .36. They both use Maxi-balls from time to time. I am relly impressed with the performance they are getting out of the Maxis. The CVA .32 is a tack driver with those cute little things, the .36 is good but not up to the .32s performance.
Occasionally you can find .32 and .36 TC molds on ebay but they quickly get bid up to very high prices. The .32 molds are espicially hard to get so they command higher prices then the .36 maxi molds. I was fortunate to get a .32 Maxi-Ball mold for a great price when I bought the CVA .32 here on the forum. The .36 mold I have is made by Lyman and it is a 4 cavity Maxi-Ball gang mold, that came from a local gun show and cost $80 without the handles.
Are they as accurate as patched round balls ? Well the .32 Maxis in the little CVA squirrel rifle sure is. The .36 TC Seneca definately likes patched round balls better but it will produce 2 1/2 -3 1/2 inch groups at 50 yards with Maxis. I have tried store bought Maxis in it I bourht at Dixons and they shoot the same as my home molded ones, maby it is the rifle but to compare the 2 1/2 - 3 1/2 inch groups from the .36 maxis to the beautifull clover leafs the rifle produces with patched round balls is simply night and day.
Before you spring for a mold buy some Maxis and try them, see how your gun likers them. Chuck Dixon has .32 and .36 Maxi-balls in stock , call him at 610-756-6271.
