5 of 5 NSA Hollowpoint Slug .2175 Cal .22 (5.5mm) Cal Reviews
Packing always great and slugs were as expected. Just wish I could find some that grouped.
Great slug out of my Daystate huntsman regal shot a string of 6 5 shot groups with an average of .81 inches on a very windy day
Wish the bc was a little better I measured them at 0.046 bc from muzzle to 50 yards still way better than pellets
If your shooting these in a standard chocked lother barrel try the 217 diameter
Shoots great out of my marauder but not so well out of my gauntlet. Too light for the gauntlet.
Love this round
No change make some heavier

I'm very much a novice when it comes to slugs. The Raider barrel is choked and should not be slug friendly. The slugs fit the magazines without issue and chamber well. If hole in hole accuracy is your Grail then this might not work for you. However for hunting they performed good enough. Perhaps a cleaner version of this slug would perform better.
This batch was fairly dirty. The package had lots of "flak" and the hollow point on many were deformed. Maybe a little better QC.
I purchased these specifically for my Beeman Raider. I had tried Brimstone slugs in the Raider before and they worked well but Brimstone slugs and pellets pull to the right 1 1/2 mil-dots consistently and are heavy. I was hoping to find something that didn't require me to adjust. I fill the Raider to 3300 PSI and I ride the shot curve. It's sighted in at 50 yards for FTT's. I then move to 16 gr, 18 gr and finish at 21.5 gr pellets. Due to wind I kept my target distance to 50 and 65 yards. At a fill of 3300 PSI I would normally add 1 1/2 to 2 mil-dots elevation for a 18 gr. pellet. I added 2 mil-dots and whiffed on the target. Quickly realized that despite the added weight and drag of the slug I was very close to zero. About a 1/2 mil-dot was all that was needed. I achieved .60-.76 ctc with a cross wind. At the low-end of the power curve l averaged 858 FPS. For context, I can launch 21.53 gr pellets at peak power around 870 FPS and shoot out to 125 yards keeping them inside 2 inches.
