Anyone using this bullet? What on and preferred powder?

I reload 221 FB with the 40 gr Vmax and use RL 7 and H 4227 with great results

I plan on using a AR with 1x10 20" barrel on pd's and maybe yotes.

Anyone using 40-grain Ballistic Tips?

Me! I shoot a lot of 40 gr Nosler BT's. Lapua cases, CCI BR primers and H335 powder at a near max load. First barrel liked 27.3 grains, but that's too hot for barrel two. Twist is 1 in 9. Shoots tiny groups.

That tiny little pill will knock a coyote flat. Amazing. I started using that bullet because I wanted one that would fragment rather than ricochet.

603, I have around 1400 I want to exile...they were over-runs or seconds, don't recall which. I actually need to take them to work and weigh them on a scale that's more precise than anything I have here at home, because I'm not about to count them all. That way I can come up with a more accurate estimate of quantity. If you're interested, PM me.

I have used them in a K Hornet

I'll let you know in about a month,I've loaded up some with 13 grains of blue dot for a 223 to use on a prairie dog shoot in Oklahoma panhandle.Never used this load before and am anxious to try it on close dogs

I shoot them in a 1:12 CZ 527 in 223. BLC(2), and get great results!

It loves H322 in a .223, coyotes not so much. No exit, DRT.

I shoot them (40 VMAX) in a 1-12 twist CZ 527. I don't recall exactly, but charge is around 27-28 grains of W-748. They are smoking along about 3400 fps and do not exit coyotes. Shoot pretty tight little groups out of that CZ as well. But in my rifle the 50 spitzer Dogtowns shoot just as good, and are cheaper. The 50 Dogtowns do exit on some coyotes, but sure put them down hard.
