.177 Pellets VS Slugs Wind Drift in 20 MPH.... For new guys or guys curious. Short version up front.
Wind Drift 20mph from East To West. 5 different pellet /slug types in .... Comparing Wind Drift

1. JSB 16.3 Grain Mosters All over the place NA
2. 8.4 Grains Wind Drift 5.25 inches
3. 10.2 Grain Pellets 4.75 inches
4. 13.4 Grain Knock Out Slugs.... 2.5 inches
5. 10.2 Grain Knock oust slugs.... 2.25 inches

I just started experimenting with 177 slugs.
I have only compared the 13gr pellets and 13gr slugs.. on a no wind or very little wind with the 13gr pellets tuned in they shot great. Same with the slugs tuned in.. what I mean by "tuned in" the pellets like 850-880fps is where they grouped best at 50yrds.. slugs tuned in best at 920fps (they would also group well at a faster fps but the rifle sounded best at 920)
I have noticed in a Windy condition that the slugs did better hands down...
Great video in showing the difference in slugs vs pellets...

my experience is like this:

The 16,2grain Beast in .177cal are stable up to a certain distance like 50 yards. From here they are no good. Here are lighter weights pellets better. Even though I haven`t tested in a windy condition it still confirms the 16,2grain Beast are spinned just barely enough or their aerodynamics isn`t the best. When this written at 45 yards the beast makes one hole groups using a Daystate Revere. Try to use ZANs 16-20 grains. They all do ekstremely well..

Thank you for your video. I am in the process of looking for the best .177 pellet for my new Crown Mk2 with 500mm barrel and am interested in the 16.2gr JSB. I was a bit surprised at its performance in your test. Unfortunately, I haven't been able to test accuracy due to weather conditions (cold & snow). I started a thread in the projectile forum asking for input on the .177 16.2 JSB pellet and the general consensus was that this pellet performs best above 900fps, preferably mid to high 900fps.

I am curious if the pellet form factor and mass has a significant impact on the velocity a particular form factor pellet is at its most efficient. A picture of the various pellets I am looking at is below.

hmmm... well this is a tough question. I know some swear by the 16.2 pellets. For me they seem to destabalize more than other pellets. If you look at the side profile and the length also some pellets / slugs have a lower tolerance for stability and the JSB might be on of them even if flown at the optimal speed. For me at some point your pellet will slow down from 1000 fps to 900 to 800 on down. I guess I look at it as the pellet that is the most stable across all those speeds would apear to work well at extremely long range. I have seen some slugs great to 150 yards then after that they go crazy bad. Just my take hope it make sense.

You are right Jaydog beast have to be shot very fast .... when they get under a certaIn speed they will start flying in spirals. Thats why 1020 fps keeps the speed up furter for long range shooting....
If you shoot them at like 920 fps they can be awesome at 30 yards but not even hitting the target sheet at 60 yards. Try to treat them as heavy slugs snd will be surprised and pleased.
