5 out of the 70+ rounds had an "off sound" which were obviously of lower velocity and charge, but printed on paper somewhat closely to the parent group. Through 70+ rounds being shot through 2 different rifles, there were 4 failures to fire. Drop from both the 17" sporter and 20" heavy barrel was 2.5" from the 25 yard zero. A 1.25" group with the 17" MKII F, and a -1.5" group with the MKII BV heavy barrel. Not expecting much, i was actually really surpised. So I picked it up a notch and went to 50 yards. With the heavy barrelled MKII, a horizontal and vertical spread of just under. I found the group size to be actually impressive, albeit only 25 yards through a MKII F and especially a super low velocity in a cross wind. Rim Thickness produced 6 lots and ranged between. The ammo weight lot seperation produced 8 weight lots, and ranged from 44.4 (1 round) to 46.0 grains (3 rounds), favoring 45.1 grains with 12 rounds out of 50. A hint of lubrication was present, however very minimal. The lead bullet was copper washed, a few lookes as if there was some sort of scaling around the driving band. In addition, there were slots cut into the tip at 12, 3, 6, and 9 o'clock, no doubt to assist with fragmentation / expansion. The bullet itself looked quite wicked - a true truncated coned head with a large cavity hollowpoint. The rapport of the ammo was substaintially lower than that of High velocity, and also noticably lower than standard / match / subsonic velocitied ammos. A deviation between the lowest and highest FPS reading was only 36 FPS. With a 25 yard zero and not making any adjustments, a 2.5" drop. I chronied an average of 736 fps 10 feet away from the muzzle. The advertised data on the back of the package read that it had a 33gr truncated cone bullet and velocity was 740 fps at muzzle, 687 at 50yards with a 25 yard zero, a 2.7" drop at 50 yards. I never was a fan of Remington ammo of any caliber, so I must admit I was biased from the start. 10 round groups were measured outside to outside spread.įirst, a breakdown of the Remington CBee 22 ammo. Temp was 78 deg F, sunny, cross wind of 3 to 7 mph 3:00. The magazines were loaded 1 round each of the different weight lots / rim thickness of each ammo to ensure an objective "mix" of what can be encountered, or if taking the rounds straight out to the box.

Some of the group testing was a MKII F, 17" sporter barrel. The rifle used was a Savage MKII BV 20" heavy barrel. I only took the first 50 rounds of the box to do the weight and rim thickness sorting, as that should be enough to give an example of the rest.Ĭhronographing was done 10 feet from the muzzle, average on 5 rounds shot.

I started analyzing the ammos the usual way, weighing and rim sorting, then chronographing. Yes, there is also Aguila SSS ammo out there that fits into the same classification / use as the subject ammos, unfortunately not availble at the store I was at.īoth ammos came in a 100 round container, price on both was $9.99, or $.01 a round. So having both of the subject ammos readily available at the store, I purchased both and figured to do a little test while in hand. For the record, if it wasn't for the offensive / defensive actions the foxes were taking, I wouldn't have been looking for a "solution". Recently having a population of 5 grey foxes move under the neighbor's shed (and the subsequent losing the fear of people, aggresive stances taken against myself and my wife) had me at the store looking for a "solution". These 2 specialty ammos are generally used for backyard pest removal among other applications where "stealth" is required - low noise / less detection.
