The Shepherd 3-10X40 P3 rifle scope is specifically designed for flat shooting high powered rifles.  This general purpose sight is like no other rifle scope on the planet.  It is far and away the best moving target acquisition rifle scope system available today and is a must have for the avid shooter whether as an addition to their tactical gear or hunting gear.  The P3 has Shepherd’s patented reticle range finding system designed specifically for modern rifle platforms.  It also features Shepherd’s One Shot Zero Feature allowing the user to dial in the gun in a single shot.  This Shepherd rifle scope gives shooters the fastest, one step, target range estimator and ballistic drop calculator in the world.  This unique rifle scope allows even an inexperienced shooter the ability to just “Fit and Fire”.  The rifle scope features Shepherd’s PVD multi-layer coated HD optics which deliver a crystal clear image through the entire field of view.  The model 310-P3 has 18” range-finding circles for use on large targets including deer and military silhouettes.  The circles can be adjusted up for flatter shooting rounds or down for rounds with a bit more drop.  This rifle scope is ideal for the AK47, Kimber 8400 and the Mauser 98.  The bullet drops match up well with the 222 Remington Hornady Vmax super performance 50 grain and lapua 22 55 grain full metal jacket. In addition the P3 accommodates some of the more powerful game loads such as the 375 H&H Mag which delivers a foot ton of energy at 500 yards.  It also works on short barrels like the .308, 30-06 and .223’s.  If you want to check the fit of this reticle to your gun/round please visit our scope finder.  This is definitely a must have hunting or tactical accessory for anyone using high powered flat shooting rifles.  This rifle scope is extremely accurate at all distances out to 1000 yards.  You can purchase this rifle scope here by selecting the “Add To Cart” button or find a dealer or store near you using the locator at the top of the page.

    I’ve owned a Shepherd P3 scope for about 10 years now, last year I visited friends in Vegas & went to their 1000 yd. Range, shot a 3 1/2″ group @ 400 yds. With my 300 Win. Mag. Hunting gun , amazing! I had a Leupold on that rifle for twenty years and hunted all over with it, but never could I get groups that small, I now own 3 Shepherd’s! Mahalo,WDB
