just got a new thompson omega inline 50 cal. Gave my old cva to the nehpew althogh for a few hours i considered trying to get it back from him. Took the new gun to the range. I always shot cast bullets in sabots in the old gun and had no problem getting 1.5 inch at a 100 yards out of it. Well i took a can of goex pinicle and some 44 and 45 cal bullets between 250 and 350 grain and the both sized sabots. I couldnt keep 3 shots on the paper at a 100 yards! I tried both calibers of bullets and nothing seemed to do it. When i got the goex i was clumpy in the can and i had to break it up so i brought it back and picked up a can of 777 that helped but i was still shooting about an 8 inch group at a 100 yards. Next i figured maybe it was the scope. i had put a old redfield 2x7 that had worked in the past but i wasnt confident in it so i went and bought a new scope for it. Same results. Well i was about to pack the gun up and bring it back figureing the something was drasticaly wrong with it. I got to looking in the box and it came with 6 ballistic tipped jacketed bullets and sabots. So i figured what the heck id try that. With 100 grains of 777 then shot into two in. Wow i was getting somewhere. I figured id go buy some more and be done with it but my cheap side won out. I knew i had a box of 250 xtps on the shelf at home and never had a use for them. I ran home and got them and they did 1.5 inch with 100 grains of powder and 1 inch with 90. Now tell me why this is. I shot 3 differnt 250-255 grain 45 cast bullet sized to 452 in the gun and couldnt keep it on the paper and 250 jacketed shoot into an inch. For the life of me i cant see why!!! I figured first it was the twist as it shot heavier bullets worse but both of these bullets should stabilize at about the same twist rate.
