Extensive Vang Comp 870 Super Magnum Test Results!!!
The purpose of this extensive test was not only to evaluate different brands and types of buck and slugs with the 870 Super Magnum Vang Comp System, but to also find keeper loads for the area of combat buckshot, slug, and Super Magnum Buckshot (for big game). That is a round that proved itself to be superior to the rest of it's class. Not just in one area, but a round that incorporates the best of pattern, velocity, price, reliability, and recoil.

In the end, I decided that Winchester's "Double X" Copper Plated buffered 12 Pellet 00 load was that round. Not only did it produce the best velocity figures out of all the buck loads, but it was very consistent, had 3 extra pellets, and patterned tight to boot. I just ordered 250 rounds of this and am currently phasing out other buck in my arsenal (I just want to stock the 3 "keeper" ammo types, not a misc. selection for each)

Though it patterned the tightest at all ranges, I did not choose the Estate round for several reasons.
1. It is no longer in production
2. Over longer ranges the lack of 3 pellets makes the pattern less dense even though it may be tighter
3. My gun sometimes jams with this load for unknown reasons.

The slug I choose to incorporate was Brenneke's 3" magnum slug. Because it is the most powerful slug, and if I choose to utilize a slug I want to be able to have the power to penetrate, and not have a soft lead pancake instead)

The Super magnum buckshot round I choose was the Nitro 3 1/2" 0000 (Twelve .38 cal pellets). This round produces over 2,800 ft/lbs at the muzzle out of my gun, it is the ultimate close range stopper. If I need immediate stoppage at close range and this round doesn't stop it, nothing handheld will. This is a good round to have chambered when one risks a close encounter in bear country.

These are the rounds I have chosen based on the results I have obtained. Feel free to read my test results and let me know if you think I made the right choices, and if not, what rounds you would have picked instead.

[/B]Wild Tests:[/B]
Rapid Fire 10 rounds of Sellier and Bellot 12 pellet 00 Buckshot at ~65 yards.

First test (Wild 1) was to rapid fire shots as fast as possible toward target without taking time to really line up the sights exactly. AKA just point and shoot mode, reflex shots. This was designed to simulate stress/panic mode during combat.

Second test (Wild II) was rapid fire aimed shots, to fire as fast as possible while first making sure to line up the MMC ghost ring sights to the target. This is designed to simulated concious, cool headed, controled fire under combat.

Test Results: Number of pellets on paper. (Number of pellets on silluet on the paper)
Wild I: 8 (6 on target, 2 vital headshots.)
Wild II:28(19 on target, 8 vital shots on head, neck, heart, and lung).

Clearly, it is better to try to keep a cool head under combat and fire aimed shots. Even though it may be half the speed, not to mention hard to keep a cool head under the stress at combat, it is clearly over 3 times as effective to the target than point and shoot/spray and pray un-aimed shots with buck at that distance.
