445 super mag Contender?
I got one in Super 14. It is a rechambered 44 Magnum. Accuracy is so-so. By that I mean 1.5+ at 100 yards with most of the bullets and powder combos that I have tried. Most of my effort with it was with cast bullets, so I may not have a true evaluation of this cartridge. I was shooting a 320 grain (Lyman 429650) at velocities of 1500 fps and 240 grain (RCBS 44-240-SWC) at velocities of nearly 1800 fps. Various jacketed bullets (210-240 grains) were also used, but my main concern was cast bullets.
I am absolutely not recoil shy but this cartridge is very eye-opening and wrist-wrecking when the hammer hits a full, near maximum reload
Period. I have shoot nearly 50 rounds at one setting, and my wrist and palm on my right hand suffered for several days after
It is not for someone who hesitates even minimally when recoil is a factor. I am sure you will hear other opinions, but maybe those people are just a bit tougher than I am. So be that
Scopes are another issue. I could not keep one in place no matter what I did. Note: I was only using a two-ring system. I have several three-ring systems on other Contenders, but I just never got around to changing one of them to the 445SM. Guess I sort of lost interest when I could not get M.O.A. accuracy. So, 3 or 4 ring systems are a must. The Burris scope held up under nearly a thousand rounds before I put the project on hold. Brass can be pricey also.
I am not trying to discourage your thoughts on a 445SM, but be aware that it comes with challenges other than achieving acceptable accuracy. Good-luck with your venture
