    Apparent proof - relationship between grains & fps

    I have in an earlier thread on this forum theorized that the amount of powder required in a handload goes up with the SQUARE of the velocity required. I think I accidentally got proof the other day. I was testing the new 250g Hybrid Tactical 338 bullet from Berger in my TRG Model 42 in 338...

    Reloading in an Apt?

    Re: Reloading in an Apt? My wife and I live full-time in an RV of 250 square foot size. Reloading is no issue at all, provided you think about where you are going to store something before buying it! A good reloading setup need not be either large nor obvious to visitors, if there is a...

    Why isn't the most accurate load the max load?

    Re: Why isn't the most accurate load the max load? I think there are MULTIPLE factors, and one problem is that (a) we individually don't know all the factors at work, and (b) we have a hard enough time controlling the ones we know about. But, that is what makes reloading so interesting to do...

    Why isn't the most accurate load the max load?

    Re: Why isn't the most accurate load the max load? X-fan: I'm afraid I would need to be better persuaded of that. ONE example of why: Very few handgun loads attain 45,000 psi, and yet there are excellently accurate handguns. The lowly low pressure .22 in fact is very accurate in well made...

    Why isn't the most accurate load the max load?

    Re: Why isn't the most accurate load the max load? I'll add another dimension to this: I have foudn over the years that getting more velocity requires disproportionately more powder. In other words, to get "x" % more velocity, you need to add MORE than "x" % more powder. This makes sense...
