Cheers Phil. I was originally hoping for 3000fps so 2923 is close enough. I will seat the bullets longer next time to see if that helps to tighten the groups. With a bit of playing around I found that my Tikka T3 in 270win if I seated 10 thou off the lands and that gives me a ragged hole at 150 yards. I have found that some bullets/rifles like a bit of a jump, some like it nearly touching the lands. I agree that 1 1/2" group at 100 yards is generally speaking fine for most animals, but near the top of my list are some of the tiny species. Common duiker, grysbuck, steenbuck, they have a smaller vital area maybe smaller than 6"? Also when I am at home a smaller muntjac deer has vitals of less than 6" also. So the tighter the group the better. I am also going for chamois in the French alps in November, they are a small animal plus the average shot is >200 yards, sometimes further!!! A 1 1/2" group at 100 is 4 1/2" at 300 yards. Could result in a wounded or lost animal, which nobody wants!
