B&P 12 gauge Rifled Slug Review
 

I think it is about time for a few target photos and some chronograph numbers. 

Since my shotgun of choice for Front Sight is a FNH SLP Mark1 with an EOTech XPS2-0 holographic weapon sight, I used it for this evaluation.  While shooting for accuracy, I also ran the slugs over my PACT chronograph.  Unless otherwise noted, the targets were shot from 50 yards off of a concrete bench with the Mark1 resting on a couple of sand bags.  Group size determined by the center to center measurement of the two holes furthest apart.
 

My slug load in the past has been Federal Truball, a 1 ounce reduced velocity load.  It is rated at 1300 FPS (per the packaging).  I've used this for three shotgun classes at Front Sight.  I grabbed a couple of boxes and brought them along to establish a baseline. 
 

Federal Truball 1oz. 1300 FPS

# of Shots:  5
Lowest Velocity:  1273 FPS
Highest Velocity:  1285 FPS
Average Velocity:  1280 FPS
Standard Deviation:  4.6 FPS
Grouping:  7.5"
Barrel Choke:  Improved Cylinder

The above Truball group is one of the worse groups I've shot.  They usually perform better than that.  However, this group was not the first group shot today.....it was after a group or two of the B&P slugs had gone through the gun.  Regardless, this was what they did today so that is what I'll include in this review. 
 

B&P 12 ga reduced recoil slug target #1

B&P 1oz. 1200 FPS
# of Shots:  5
Lowest Velocity:  1156 FPS
Highest Velocity:  1177 FPS
Average Velocity:  1168 FPS
Standard Deviation:  8.2 FPS
Grouping:  2.4"
Barrel Choke:  Improved Cylinder

 

With a few slugs down range, it was time to do a quick adjustment on the optic to get it the slug impacts closer to point of aim.  Since I couldn't remember the amount each click on the EOTech would give me, I dialed 12 clicks down and put up a fresh target.

 

B&P 12 ga reduced recoil slug target #2

B&P 1oz. 1200 FPS
# of Shots:  5
Lowest Velocity:  1171 FPS
Highest Velocity:  1184 FPS
Average Velocity:  1178FPS
Standard Deviation:  4.8 FPS
Grouping:  2.8"
Barrel Choke:  Improved Cylinder

 

Having shot the previous round using the IC choke, I decided to try the S&B slugs with the modified choke. 


B&P 12 ga reduced recoil slug target #3

B&P 1oz. 1200 FPS
# of Shots:  5
Lowest Velocity:  1150 FPS
Highest Velocity:  1181 FPS
Average Velocity:  1168 FPS
Standard Deviation:  12.3 FPS
Grouping:  5.4"
Barrel Choke:  Modified

It became quite obvious that the B&P slugs didn't much care for the modified choke in my Mark1.  It makes we wonder what they might do if I tried a cylinder bore choke (which I don't have).  Had there been a single flier, or perhaps even two fliers with the other three tightly grouped, I would have blamed myself and opted to run another round of 5 shots.  However, given the pattern as shot, I don't think it was me (not given my shooting of the previous S&B groups). 


Update:  09/24/2010

I spent some more time at the range and had a chance to shoot these some more.  Something just didn't seem right as far as the felt recoil was concerned.  The Federal Truball I shoot is a 1 ounce slug traveling at 1280 FPS out of my semi-auto.  It is a reduced recoil load, per Federal's web site and packaging.  Shooting the B&P slug was really quite notably softer in the recoil department.  It just didn't make sense that 100 FPS slower would soften up the recoil that much.

When I got home, I plugged in my RCBS digital scale.  After it warmed up, I calibrated it and then put the B&P slug that I removed from the hull a few days ago on the scale.  Hmmm......370.7 grains.  I sliced open a Truball slug and weighed it.....437.7 grains.  1 ounce is 437.5 grains. 

Doing some quick math, it would seem that the B&P slug is not at all a 1 ounce slug but just slightly on the light side of a 7/8 ounce slug.  The reduced weight and reduced velocity better explains why the felt recoil is notably less than the Federal Truball slug. 

My faith in this slug going the full distance, in regards to properly cycling my semi-auto once it gets dirty, is not real good.  I'll just have to see how it performs.
