I love those rubber slings. They are not only easier on the shoulder, but you can wear them in multiple ways and the rifle stays put.
I've also started putting my rifle on my pack, with a quick release, if I'm hiking. It helps a bunch.
Evern since I bought a borescope I've found all kinds of "interesting" things, but I use it mostly to check cleaning. I have a Cooper in .223 that has slayed thousands of prairie dogs, and continues to do so. I promised myself I wouldn't scope that particular barrel until I missed one.
That's the trouble I've had with this method. There has to be low Es for a single shot to show what you want. So, sometimes it works, sometimes it doesn't. My 6.5-300 Weatherby is one place where it didn't. The flat spot wasn't flat when I reshot it just for my own sanity. I've found this...
Never, ever use tarnished brass. In fact, don't keep it near your non-tarnished brass, especially Lapua. You are in a dangerous situation and you should immediately send all your Lapua brass to me to alleviate your risk!
I can attest the Lee crimp does not increase muzzle velocity by 300fps. Not that I dont like Lee FCD crimps, they are very consistent. I've run lots of crimped vs. not crimped comparisons.
Some of the bullets I pulled were in there so well it stressed the press to get them out.
I pulled out some loads from 2015 in 300 Weatherby to get ready for this year's Elk season. At sight in the velocity was quite a bit higher than my notes showed. I had loaded some new rounds using the same recipe and the velocity was 300 fps lower ... hmmm.
I pulled a couple of the bullets...
I've never paid much attention to case weight (primary interest is hunting, but I always strive for smaller groups) but I decided to weigh a series of 300 Weatherby cases due to another problem I was researching. Unfortunately, I didn't keep my cases separated by lots.
I got a range of 216 to...
It is a laser/death ray. Unlike Fotis, I've had a little more trouble finding loads but it was worth it. I tried RL33 but did better with US869. The 127 LRX seems to be designed to reach way out there with the 6.5-300.
