I bought some of these in 50 cal to try in Traditions rifle 1/28 twist using 452 cast lead bullet 240 gr the 50 yard group was more like a shotgun pattern about 2 feet with 60 to 70 to 80 to 90 grains Goex 2 f this gun stacks maxi balls into a cloverleaf at that distance So my question is has anyone used these with any success This was the worst accuracy I have ever seen
