I understand that you don't have much money to spend on "top-flight" equipment. But, spending just a little over $30 to get a jellyhead choke is a good idea, if it is possible. for $10-15 more than you aim to spend you can get a choke that is not only very good, but in my humble opinion vastly better than any $30 choke out there. The jellyheads seem to pattern pretty well with just about any load. Not sure how easily you could find one for a pardner pump, but if you can find one I'd think long and hard about it.
Wish I could hunt all year long.
I have more bows and guns than I used to, but not enough.
