    Rifle Scopes Zero Compromise Optic update

    @CSTactical you wanna set me up with a straight trade? Lightly used 527 MPCT1 for an MPCT3? ;)

    Time to start applying centerfire logic to .22 (was just zero, now expanded to other areas)

    Hell, when I get a 22, the ZCO is probably going to spend some time on there too! 25m parallax and a boatload of elevation travel is perfectly suited for a precision 22. So the question here is what range increment to base a rimfire "mph" on? For centerfire, it lines up nicely that we use 100...

    Time to start applying centerfire logic to .22 (was just zero, now expanded to other areas)

    I definitely considered this a couple months ago. I don't have a .22 yet, but I've shot NRL22 matches with loaner rifles. I definitely agree with you that a 22 zero needs to reflect the same ideals of a centerfire zero. When I took a look at it, 30 yards seemed ideal because all adjustments were...

    2020 Road Bike Thread

    Got into road cycling last summer, rode a steel frame I put some modern parts on for a bit. Few weeks ago, got a great deal on a Trek Emonda ALR frame from a friend of mine and moved some components over. Been training for this race season after a guy at school saw some of my Strava rides and...

    25x47 Lapua

    The .330 G7 that BlackJack publishes is very consistently low, and they know that, but would rather send conservative numbers out to people. .330 will put you over the top of smaller targets at and past 800. .340-.345 G7 is what most people use to good effect.

    Left-Hand Gain Twist

    A 1-7" ending twist would put you around 278,000 RPM at 2700 fps, and I don't think you'll be going that fast. There's no magical number, but once you get up in the 300,000 RPM range and above, bullets start thinking about coming apart. Some handle upwards of that really well, but 300,000 RPM is...

    Curtis Customs Jumping In

    Rumor I've heard is that they're officially announcing next month...so maybe we'll see more soon

    Curtis Customs Jumping In

    Yeah, I definitely get this. Vudoo is going to have a huge piece of the market shored up already, they were first to the game. With how well they did it, I think it would be nearly useless to try unless your action was offering something unique (60 degree throw, lower price point, etc.). This...

    How many here salt bath anneal?

    That was the one thing I thought was suspicious about AMP's testing. They weren't really showing how they arrived at the "ideal anneal" numbers that they set as the standard

    How many here salt bath anneal?

    But it doesn't quite manifest itself the same way. A case can be softer/weaker after annealing and still not be "correctly annealed" according to AMP's research. This would mean that you could extend case life and increase sizing precision (by reducing brass springback), which SBA has been shown...

    How many here salt bath anneal?

    Hell, I'm a student. That would be a great project. Just gotta get access to a Rockwell C hardness testing platform...

    How many here salt bath anneal?

    Home-made induction is probably the best bang for your buck. I do SBA, and I've seen the benefits of annealing (increased brass life, less shoulder springback, more consistent neck tension, lower ES/SD, etc.), so I don't completely agree with the conclusions reached in AMP's article (the...

    So when do we label the troller of the known trolls a troll himself? :unsure:

    Rifle Scopes Arken Optics EP-4 Tracking Test Video

    Saw these a few weeks ago on Facebook and recoiled a little at the price (thinking you get what you pay for). If these continue to track and the company stays on top of their customer service, I could see one of these making it into my safe. Wish either this or the Tikka T1X was about $30...

    257 WBY Mag ELR Suitable ?

    If you want to do a 25 cal, use the 131 gr ACE from Blackjack. Best high BC bullet for the 25 cals right now. A 257 Wby is going to be fast and flat with relatively mild recoil. Preliminary numbers put it at 4.7 mils to 1000 yards, 11.3 mils to a mile, 16.2 mils to 2000 yards. Subsonic at almost...
