No thats a good buy. I have about 250 of the 240 LSWC's left that I got when I was in Rapid City SD. There is a bullet casting outfit there called Rushmore ammo where I used to buy tons of bullets. I quess a guy doesn't need Gas Checks until you get up to 1400 fps or so depending on the lube and Hardness. Thanks for the info. I really like the Cast Performance that I picked up at Cabelas. I got the 300 but they had 320 grainers to. I think they are all gas checked but a guy inn't gonna drive them to fast in the 44 Mag handgun. When I chronographed those the first time, I thout the machine was on the blink. The velocity was like a carbon copy. I can shoot them at 1000 fps in the Ultralite but the recoil is a bit sharp. 900 ain't bad.
