well i finsihed last weekend making up a batch of 100 rounds in 22/250. followed the Hornady book gr for gr.
using a 55gr v max with H380.
my rifle its a weatherby vanguard and shoots very well, usually arround a sub 1 inch group at 100 yrds.
well i tried a few out last night and discovered that 4/5 shots missed the target. so some zeroing was conducted today and would you believe it i can only achieve a 6inch group at 70yrds with these loads.
needless to say i will be starting again! and the sad thing is I Dont have a BULLET PULLER!
moral of the story: only load in small numbers when developing a load for your rifle!
