Buffalo is the brand and it is a small 245 grain conical with a ball-like ogive. PA conicals are an alternative made by Hornady. Both are inexpensive and both would work for the purpose. I have to order mine by mail. I have found the best place to order most bullets is archeryexperts.com (tom richmond or something like that). They have good prices but more important, they don't slap you with high shipping and handling. So even while the price per boxmay be higher than cheaperthandirt.com or some other discounters, the final priceon many orders ischeaper. You'll have to test to know for sure though. Good luck with your sidekick!
