As I come across different buckshot in a sufficient quantity that I feel is
worth patterning, I'll continue to add them to this write-up.
I recently picked up some B&P "00" buckshot when I was ordering some of their 12 gauge slugs. These are made by Baschieri & Pellagri in Italy and I purchased them from an outlet in the U.S. The 10 round box states a 1 1/6 oz. load so I decided to open one up and see what was inside. The powder charge was capped by a plastic wad. A fiber wad, sitting on top of the plastic wad, took up the remaining space not used by the 9 pellets. The pellets measured .340" in diameter, which equates to the 8.6mm marking on the box. This is just a bit over 00 buckshot pellet size, which is typically .330". So, we have the European equivalent of 00 buckshot, give or take a ten thousandths of an inch.
So how do they pattern? Let's take a look.
The above target is the standard Front Sight target that I use
for my normal range practice (when not shooting for group size with a rifle).
It was shot with 3 rounds at a distance of 15 yards using an Improved Cylinder
choke in my FNH SLP Mark1 shotgun. Each round was marked after each shot
and then color coded when I got home.
This target was shot with 3 rounds at a distance of 15 yards using a Modified choke in my FNH SLP Mark1 shotgun. Each round was marked after each shot and then color coded when I got home.
As I usually do, the loads were run over a chronograph to see just how they were doing in the velocity department. The average velocity for a 3 shot string was 1296 FPS with standard deviation of 12.0. The chrono was placed 7 feet from the muzzle.
The pattern on both of these was larger than some of the buckshot I have used at this distance. Both targets already had pellets outside of the "B" zone at just 15 yards. The modified choke target had two pellets that missed the target. While not colored on either target, the single head shot at 7 yards kept all the pellets in that portion of the target.
This is yet another example of why you need to carefully pattern your shotgun
with the buckshot you are considering. If you don't, you may be quite
surprised how the loads perform.
