biglmbass,
Thanks for the info...I reloaded some 300gr XTPs and they fit (w/ 1/16" to spare) if crimped at the first crimp only. All my 240s fit fine. The only problem I ran into was on the first shot, the clip stopped feeding. Upon dissasembing it, I found the spring had come out of its hole. It took awhile but I finally got it back together and haven't had any trouble since. I was shooting one big ragged hole @ 50 yards
and about 2" at 100 yards. This is an accurate, light weight little brush gun.
