You don't need expensive pellets to break in your Venom. Go to Wally and get a couple of tins of CPHP's, Crosman Premier Hollow Points. They are less than $10 per tin. Shoot a tin of these, then you can start looking for a more accurate pellet. If you're lucky, your gun will like the CPHP's.
Yeah those cphps will work for break in, but they are not the best in . 22 Cal.
Any 14-16 grain pellet will do you fine. You just want to lead the barrel, break in the seal and burn off any combustibles in the chamber. I have used Daisy HP and they also work fine at $5/tin they are now my break-in pellets.
