I guess I will get in on the Leupold thread. This is from about 100 pages of my hunting and shooting records.
Leupold came out with a 2½X-8X hand gun scope. When I first called to asked if they thought it would handle the recoil of the .454, the fellow very confidently said,
"You'll want to give that pip squeak pistol of yours to your grandmother. Your .454 Casull can only generate 850 "G" forces. Out testing machine generates 1800 "Gs". Our 2½X-8X has endured 10,000 jolts and is still fine."
After several months they were on the market. With a little trading, I was able to get one. After several months they were on the market. With a little trading, I was able to get one. After the failure of the Burris (twice), Bausch & Lomb (twice), Bushnell (thrice), Nichols (once), and the T/C Center "Recoil Proof" (twice), a Leupold 2½X-8X was installed. It failed after three years of service. Leupold replaced it with their "new" model at no charge. The glass appears (no pun intended) to be better. It endured thousands of full throttle rounds. My favorite was a Freedom Arms 240 grain at 2,014 feet per second.
