Yeah i agree with you guys, each year I have been trying different loads for my 7mm, to see on whitetail what offers optimal expansion, and accuracy, hunting in maine can be difficult because we have alot of mixed terrain, shots can range from 20 yards to 400 yards, this last fall was the closest shot I have ever had on a deer, the buck came out of a thicket into a clearing I was watching, only problem is he came out about 20 yards up the clearing from my blind. Now the deer I speak of trailing was hit by my cousin using 175 Remington Core-lokt rounds, he hit just behind the rib-cage at around 125yards, I think that due to the heavier bullet the lead didnt expand like it was supposed to, but so far the best Ive found you can't find anymore in my neck of the woods, the Winchester Supreme 160grain Fail-Safe, the last 2 deer Ive shot have been with 140grain Remington Premier Accu-Points. They seem to do what I want. I personally since I inherited this rifle have not had to track anything "Ive" shot with it, but I also make sure the rifle is zeroed at 200 yards, and I know the balistic tables of the round Im using. I was interested in the .280 Rem round because its something that I thought I might like cause of the performance was similar to the 7RM, and the .338WM I was thinking about was mostly because more knockdown power for hunting out of state. Biggest game we have here is the moose, Im sure my 7RM is more than enough for that but eventually Im going to go on a hunt in Alaska for Grizzly and I want a little more assurance, although then again I always have my side-arm which Ive seen do a number on tv to Alaskan Game, so what do you guys think try different rounds for my 7RM???
