243 winchester not grouping
Hello I am kinda new to reloading and have had good luck so far. But today I tried to make up a round for deer out of my girlfriends 243 . It is a Ruger m77 frontier with a 16.5 inch barrel and 1:9 twist. I was using h4350 and 100gr hornady btsp. The best I could do was maybe 2 inch group at 100yards. Was wondering if the bullet was to heavy for the barrel length or maybe the powder was to slow as I use it for my 06 also?
