    New 465 gr. Steve Brooks mould has produced 10 shots in about 4 inches at 200 yards today in my Shiloh .45-70. This a great improvement over the 365 gr. I had been using for 200 yards.

    Looks like you will be able to cut that group in half w/o too much trouble.

    I bought Brooks mold on ebay and it produces groups close to 1" at 100 meters.

    My Brooks mould cast really nice, bullets are very consistant and its a joy to work with.

    With iron sights I’m not confident I can get consistently tighter groups. This Brooks mould has tightened my groups down by more than half. There was a heavy cloud cover Friday, these old eyes prefer lots of lighting.

    This pic I posted turned 90 degrees somehow. The shots on the left were actually the top two first shots. The shots basically hits progressively lower throughout the 10 shot group. On the pic that would be progressively from the left to the right. I was using a blow tube, I thought would was fine, there was the typical March moisture in the air. I am considering trying the patch between shots.

    If that was a two hundred yard group on it's left side, and you started with a clean barrel? - DON'T give up the blow tube!

    You shot a fine group and you are just seeing what it can do after the barrel settles in. I once shot a week long championship match and never put a rod through the rifle... blow-tubed the whole seven days.
    Once the barrel is in steadystate and shooting it, will start putting them in there.

    Back to your target:
    Those eight shots are wide from the wind maybe, but they are no more than MOA high. Stick with it.

    Some barrels take more shots than others to settle into a constant condition. My Shiloh in .40-65 will always throw the first shot but then groups them all together ( however, it will almost always put the first shot high and to the left, maybe a minute or possibly two ). My Shiloh in .45-90 takes two to three shots before it will shoot really excellent groups. This is with wiping between shots by the way. I also precondition the bore by wiping before the first shot.

    If you go to a long range match with a limit on sighters, keep an eye on the top shooters. You'll often see several people who will intentionally put a shot or two into the berm before going for the first sighter. This is so that you don't collect useless info from your sighters before the barrel has settled in.

    Chris.

    Great advice guys thanks! I really appreciate your input. I’m heading to Rattlesnake to try a 3 day match this weekend since my regular BPCR match director is shooting the Oregon State championship this month.

    Oregon is this month? They must have some early spring weather down there! Might have to put that on the list for some future year.
