I hear you on the access to information on the web, truly outstanding!
I am 55 and have been hunting and shooting since I was 5 with my father, was I ever lucky to have the father I had, sure do miss him. Many days after school I would take out my pellet rifle (open sight no scope) and go hunt blackbirds, starlings, seagulls and squirrels. Sometimes the holdover on them blackbirds was 2 feet hehe, was nothing to shoot 20 birds an afternoon. With seagulls after loading my pellet I would drop in some #9 shot in the front of the barrel and shoot them in flight. Did a lot of shooting with my 22 once I moved up in caliber lol.
I agree with everything you have said Wildrose and after speaking with my gunsmith he basically said the same thing you have about only gaining 100 to 150 feet. He does all of my work and he also told me that rechambering a Tikka can't be done because their barrels are to hard. So as it stands I think that I will just stick to the Tikka T3 Hunter, or a T3 Stainless 7mm rem mag. Most of the killing I do is under 500 yards, in fact the longest kill shot I took to date was on a beauty bull moose around 500 yards, freehand with my 30-06. I was in a meadow with no trees and high grass, so I had no option but to freehand the shot. The moose dropped got up went 75 yards and expired.
This is the scenario that made my realize that I did not have the perfect setup to take longer shots. I was using a Bausch & Lomb 4200 Rainguard Elite and with that setup the holdover is significant and iffy. That is the day I decided to buy myself a different rifle that was flatter shooting and a scope that I could adjust and then aim at what I wanted to shoot at and eliminating the guessing game. The first hunt I went on with my 300WSM and Huskemaw was a Mule Deer hunt. I remember going out that day hoping for a long range gun)to see what my new setup would do, the deer I killed I shot at 75 yards,
foiled again haha!
I also agree that there is lots to learn about long range shooting, never did like reading that much, more of a hands on guy that prefers practical experience over theoretical. So lots of shooting is in order and will be done. As it stands now with my Huskemaw and my 300 WSM, 500 yards with a 10 inch disk I never miss, my rest is the hood of my truck on a packsack.
I have been using 180 grain Nosler Trophy Grade Accubonds in my 300 WSM. What is your favorite bullet for long range shooting on elk?
