JSB Knock Outs 10gr .177

Package just arrived....

Saw these on trademe the other night and had to get some to try.
They have had good reviews on you tube, but up till now I dont believe they have been avalible on NZ.

The only .177 slugs avalible in NZ were Sypdas 13.4gr, but Ive really been wanting to try a 10gr slug.
These have a hollow base, and a decent depth hollow point.

Going to try then in Little Elly at about 12.4FPE, so I'm expecting about 740ish fps or there abouts, and then goint to try them in Emma, hopefully around 1000fps.

So excited to start playing with these!
Will post updates as we go...

Very encouraging results so far...
Tried them through two different rifles, one didnt like them, one did.
Had a few rabbit carcasses in the back of my truck from a separate caliber test I'm doing, so put one or two of these Knockout slugs through them... Very interesting indeed!!!
Finally seeing the terminal ballistic performance I've always wanted from pellets, pity its from slugs, but it seems to be there.
More testing and then results to follow.

What guns did you test with?

nice. ive only ever used the rabbit magnum from H&N. My hatsan didnt like them at all. so that was the end of that lol

So I haven't gotten around to actual quantitive test results yet, been busy with the sub 16 comparison, but I have used these little slugs for two jobs this week, and their performance has been excellent both times!

First job was a pukeko cull. I acquired a culling permit for 15 pukekos for a client, and used Little Emma with these Knockout slugs for the job. FX Wildcat Mk3, 600mm barrel pushing these 10gr slugs at 954fps for 20.2FPE.
Shots were between 20y and 65yards, and their performance was excellent, I couldnt have asked for better.

Second job was at a horse racing track for rabbits last night.
This is a difficult property to cull rabbits on because it is very open, no cover, close to a mountain so can be windy, and there are a lot of people who walk their dogs here, so the rabbits have been well educated that people = danger because they have been chased by every dog in the area and/or I'm guessing that they have been shot at by every guy and his dog who's got a slug gun and nothing better to do on a Friday night.
Even with all my sneaky tactics I struggle to get with in 100 yards of them before they start hopping away... quite frustrating.
Anyway, I finished on 29 for the night which included two hares.
The close shots were 65yards and the longest shot of the night was 99yards.
And I was definatly able to appreciate the benefit of slugs at those distances!

Yes, I know I could have taken any of those shots with Little Elly and her 8.44gr exact at 12.4FPE and she would have been just as deadly, but you need all the odds stacked in your favour for long shots like that with a 12FPE pellet.
I definatly felt more confident and there fore more comfortable taking them with a slightly heavier and faster slug, and the MUCH better BC of the slugs is what gives them that better performance further down range.
Have a look at these stats, the 100 yard comparison blew my mind!

The Ellement ballistics app compares them as follows:

Little Elly.
8.44gr exact at 813fps. BC 0.019
12.4FPE at muzzel.
3.5FPE at 100yards, with 27.5 inches drop.

Little Emma.
10.03gr Kock Out at 954fps. BC 0.047 (huge difference in BC)
20.3FPE at muzzel (63% more energy at the muzzel)
11.4FPE at 100 yards, with 12.8 inches drop.

Read those 100 yard stats of each one again!
The differences at the muzzel are stright forward, they are what they are, but the differences at 100 yards are HUGE!!!
3.5 times the energy and less than half the drop, from a projectile that only weighs 1.6gr more!

Anyway, I was very happy with the performance of these little slugs last night on what is usually a difficult property to cull on.

I'm looking forward to recovering some rabbits in future, finding the slugs and getting some real world performance test results. More to come...
