Hello MKEE,
I have a 13" SS 41 GNR #2 with a Reeder brake that is one of the most accurate barrels I own, despite the fact that the 170 Sierras aren't known for their high ballistic coefficients. Below is a target like many I routinely shoot with this barrel - not because I'm a good shot (that's evident because as you can see - I can't hit the dime), but because the barrel is a very high quality piece. Please note that I INDEX religiously during reloading and preach INDEXING to every one who will listen. . .you may want to take that to heart also. I didn't get the groups down this small without INDEXING. This gun also has a Marine-Tex'd hangar bar in a VV laminated forend which I believe also does wonders for accuracy. I used to have a fairly lengthy primer on forend bedding here on GBO, but I don't know if it stayed around when GB changed his servers around. If you're interested, I might be able to find it again, just PM me.
First, the gun itself:

Now, drumroll please. . .the target:

The load I am using is nowhere near the maximum for this cartridge, but this one moves the 170 Sierras out at 2,350 fps. I've shot the .41 GNR #2 enough to know that within 150-200 yards, the cartridge is devastating on animals up to elk size. If I used hotter loads, I'm sure it would be even better, but the load I stay with does everything I ask of it in a spectacular manner.
Pressure? It's safe in the Contender with Reeder's suggested loads - 'nuff said. Would I recommend it? In a New York second. If you need more info, please PM me.
Safe and good shooting to you!
