Ranging with PA ACSS-HUD – Id never be so rude to leave without laying out the gist of the acronym ACSS; Advanced Combined Sighting System - Heads Up Dummy. And this can be yours for the moderate price of a Primary Arms rifle scope. This reticle is quite ingenious, really. Instrumentally designed as mil. combat sighting system, its application extends into the joyful realm of harvesting wild game.
Through a simple hip pocket cheat sheet or mental acumen you divide the multiple by MOA. The important critter measurements may vary by neighborhood.
COYOTE 18” length shoulder to rump x 27.78 = 500 / MOA measurement = distance in yards.
10” height back to breast x 27.78 = 277.8 / MOA measurement = distance.
DEER 36” height hoof to back x 27.78 = 1000.08 / MOA measurement = distance in yards.
18” width/height/depth x 27.78 = 500 / MOA = yards
10” diam. Crown to throat x 27.78 = 277.8 / you guessed it
YETI (chilled or standing) width, handle to handle or nipple to nipple 30” x 27.78 = 833 / 8 MOA = 104 yards back to the beer cooler or TV fame. The MOA measurement is the same as body portion multiple.
XY QUARRY dimension times 27.78 / MOA measurement either broadside or head-on using PA ACSS-HUD Reticle. There are other higher or lower math means to the same end.
The multiples of a target size are constants unless were speaking of Bruce Banner. Simply divide Your Neck of The Woods multiple by the length or height in MOA.
I recently purchased one of these FFP (1st focal plane) scopes with the ACSS. Im still ingraining the delicacies of it. GOTO youtube to get the real spiel on it; the users pamphlet is like a Hoover vacuum. Now it you want a scope with a top notch presentation box, go with Athlon. Their customer service is also a Hoover associate.
The particular flavor I chose was .308 WIN/.223 WIN Paisley. Im aghast really theyre on the same page. My ballistics tabulation for the .308 make the assigned BDC reticle hashmark distances laughable at times and fairly close on occasion. BDC reticles are a crap shoot. When I speak of the paisley caliber (TIC) I remember the .223 like I do Viet Nam and paisley, and the graphical devils peace sign. And the V for victory hand sign, or was it peace. Ive not assessed the ACSS BDC reticle by ballistics tables for the .223 WIN. Just my nickles worth.
