Accuracy limits of Remington 700 Police in .300 WinMag
Hi out there,
I am wondering about the achievable accuracy of my Remington 700 Police (.300 WinMag). Up front, I shoot regularly and often with calibers >= 7 mm.
I bought myself some month ago a Remington 700 Police in .300 WinMag, as I am keen to shoot long distance (>> 400 m).
As this rifle is well known as a sniper rifle and that .300 WinMag is predestined for this I was quit comfortable at the beginning with my choice. The rifle has a Loipold Mark 4 (mounted by a professional gunsmith in Germany).
At the beginning I used Federal 150 grain Speer Hot-cor SP and started shooting at 100 m in order to get used to the rifle. In my groups of shots I have had often 2 hits less than a cm apart and all of a sudden one, which was about 3 cm away from the ones before.
I thought that the reason is the commercial loaded rounds.
A friend who is quite an expert in reloading, made my some rounds with Hornady 168 grain bullets (L=84,5 mm, Powder 904, 69 grain). The groups have become slightly better; nevertheless every 3rd shot or so is more than 3 cm away from the ones before!
Has anybody encounter the same thing? Any explanations for this?
There is no question that I have had trigger pulling error, believe me!
Sorry for my English and looking forward to your inputs.
Take care and cheers from Germany
