For me, accuracy from field positions suffers some to a lot, depending on the position. The more unstable the position the more accuracy suffers. There is a picture below of a cow elk I shot in 2011 using my .338WM. I was shooting off a tall Primos Trigger Stick bipod. It was too tall for my position but would have been fine if I was shooting uphill. Instead the cow was below me and even on my knees I had to stretch out as far as I could to get the right down angle. My position was shaky as hell but the range was only about 262 yards and I was sure I could hit the cow in the kill zone. Not so, as it turned out. Instead my first hit was in the process bones above the spine. After that shot I moved about 10 feet to the other side of the rise so I could get the bipod legs below me and take a stable sitting position. The next shot was placed exactly where I aimed but the cow was still standing so it got another, which dropped it instantly. The last two shots made one large hole in the rib cage. The last shot was gratuitous in that it only hastened the inevitable, probably by no more than by a few seconds. Definitely learned a valuable lesson. And I bought a shorter, more stable tripod as a result, which I have used ever since.
The rifles described and/or pictured below are as light as it gets for me, at least for bolt rifles. Don’t know what they weigh but it is less than my walnut or laminate stocked Rugers.
No pictures, but I took my 2015 antelope with an All-Weather Ruger Hawkeye at 373 yards using a 140g Nosler AB and shooting off a Primos Trigger Stick tripod. One shot, placement couldn’t have been any better.
All of these are Ruger MKII’s.
