Well done Tophet1.
Those Sierras are an accurate bullet for sure.I used them in my 7x57 as well.

Hope the Red deer doesn't jump up at 25 yards mate or you will be disappointed !!.
It will be like blokes preparing for a Tahr hunt with long range practice and zeroed rifles for 300 yards and then stumble onto a Tahr at 20 yards.

I forgot to say "well done Afro408".
