    I've been loading up on Lake City XM885 green tip penetrators with some good deals lately. I'd rather not shoot 'em up when I go to the range with some new AR furniture I've got coming in the magic brown truck (pics soon...).

    Silver Bear makes an inexpensive 62gr HPBT. Would the ballistics be similar enough to zero-in the scope and be pretty dialed in with the steel core bullets.

    The Silver Bears are only 25 cents a pop right now at Cheaper than Dirt. Or should I just shoot the ammo I'm going to use if SHTF?

    I don't think 55 grain FMJ's would give nearly the ballistics that I am looking for. But what do I know?

    CHL,

    The sad thing is you need to sight the rifle in with the ammunition you are going to use for your primary use! ie Self Defense or what ever. Changing ammunition will most always change the point of impact some. This because even if you are shooting the same bullet weight. One may use a different powder or volume of powder that changes the pressure of the round. For example as a rule military ammunition is hotter than commercial usually. So if you change between the two the impact changes. Of course the farther you shoot the more the change. But just for plinking who cares if the ammunition is two three or four inches off at 100 yards. I know we shot Federal P223E 55gr. for duty and American Eagle (Federal) 55gr. FMJs for training. Wasn't enough difference to worry about for training or in your case plinking. But we new the duty rounds were dead on.

    I chose the 1-4x Nikon M-223 scope, which has the "Point-Blank" reticle designed for 50-200 yards in mind. I'm thinking minute of goblin a block or two away. Sounds like the real answer is try both and just make a mental note about the differences...THEN use the cheaper stuff.

    Do most rifle range have limitations on steel core penetrators? Just wondering.

    Yes, around here anyway.

    Zero w/ the good stuff then make a mental note of any changes of POA w/ the steel ammo and adjust your holdover.
