Oh man, I went out shooting my winchester x-150 today with the 385 gn GP bullets and 90 gn Pyrodex RS. I was shooting about 2" groups at 50 yards and got a bulls eye along with a couple other shots hitting the orange circle. I load up my 4th round, cap it and take aim and fire. BOOOOM! My skinny 160lb ass goes flying back and i come up off the ground like WTF was that?!! I thought i double loaded but as it turns out, i go to pick up my ramrod. Ahhhh no! Yup 130 yards up range i find my heavy aluminum ramrod. It now looks like a mini walking cane. I swear i have never felt anything kick so hard. The funny thing is, The bullet and ramrod hit 6" right of the bulls eye lol. After taking the gun apart for inspecting it checked out fine and i cleaned it and went back out and took4 more shots and got 1 flyer due to me flinching big time. After the 2nd shot i was back on the target and getting close groups. I was about 2" low at 50 yards. Yesterday i was low 2 1/2" at 100 yards so i thought it was weird that im 2" low at 50 and dead on at 100 today. Im going to do more 100 yard shots tomorrow before i call it quits untill the season starts. I got the Kentucky all sighted in and set up so that one is now ready. But man after shooting that ramrod i made sure every time i loaded it, i take it out of the barrel and set it on the 4 wheeler rack lol. Luckily i had a non breakable spare and will cut that down in size to replace the old ramrod. And i thought those 385 gn GP bullets kicked!! HA!
