Acceptable Groups

[Bruce_in_Oz]

With a 150gn bullet in a .303, 4064 / Varget / 2208 are all too show.

Try (OZ) ADI AR2206H. The ADI / Thales website will have current load tables. See also 4895, 3031 and a couple of the Winchester Ball powders.

Also be aware that the original, military acceptance spec was nothing to get excited about.

Viz:

42. Rifle, testing of, - Every rifle will be fired at a paper target, with full sight, leaf and slide down, at a range of 100 feet, from a mechanical rest. trial shots will be fired, if necessary, and the foresight will be adjusted for lateral deviation, or will be replaced by another foresight to correct vertical deviation. Then five rounds will be fired from the magazine; if the rifle fails to put four shots out of the five into a rectangle 1- inch broad and 1 1/2- inch high, or if the blade, foresight, requires to be set more than .03-inch to one side of its normal position, the rifle will be returned to the manufacturer.

Note that the distance is FEET, not yards.

And with SELECTED Mk7 ball.

Once you remove all the bedding features built into a "stock" SMLE fore-end AND change the ammo completely, all bets are off.

2MOA (ish) is well UNDER most mil-spec rifle acceptance figures for standard service rifle / ammo combinations around the world. 3MOA crops up quite regularly in the original numbers.

If you are pursuing something the size of a Red deer, and can sneak within 50m, you will put your bullet within ONE inch of its intended mark. See also "zero range" / "point-blank". Caveat - (buck fever allowing). Be also aware that the higher the sight-line (scope) is above the bore-line, the wackier things get at normal (SHORT) deer hunting ranges.

If you are chasing feral pigs from a bouncing Land-Cruiser, and shooting at ranges from five to thirty metres..................?
