Anyone know the BC for the 47 grain .25 caliber airgun “pellets” from the MP mold? These are sold as varmintknockers on eBay.

They are basically little bullets with a boat tail (a tapered tail end I mean) i lack the equipment to check the bc myself.

I think it's about 0.1 

But.... If you have 2 chronographs, it's very easy to figure out. Speed at muzzle vs speed at target, then run the numbers through the BC calculator. 

Those slugs really like the choked LW barrels with the 1:17.7 twist. But they like to be shot FAST! That's why they perform so well in the AF Condors. The Condor can get up to 100 FPE shooting those slugs. And they can be extremely accurate when shot at proper velocities.

I found a YouTube video of the guy who was working with Huben and MP molds to make these. I will post a link so you can check it out yourself:

They are specifically designed to work in choked LW barrels... also they are stable at lower and higher velocities. They say the pellets have excellent accuracy at 700fps (but of course a less flat trajectory) and up to about 1000fps.

Got to say these pellets are a perfect match for my TalonP, even though it won’t shoot them much past 725 FPS. Very accurate this speed. Groups at least as good as any other pellets on hand. I am shooting off hand with iron sights, for what it’s worth. 


today I tried shooting these at much lower fpe - like upper 30s and lower 40’s. Just as accurate... 



so for my 12 m range, these are perfect. I was kind of settling for this mold - only .25 I could find - because I couldn’t find any In stock for lighter pellets. I basically assumed it wouldn’t be great for the stock TalonP and would just end up using them with a future more powerful gun. Well, i am still looking for a .25 mold for pellets in the 30 grain range, but for now this is great. I actually like the heavy, lower speed thumping for close range shooting.
