Fella's;
I couldn't care less about stabilizing 100 grain bullets, or the Sirocco in that size bore. I found the Speer 90 grain spritzer and am not looking back. Speer builds this bullet heavier for the old 1:12 twist guns, but it doesn't matter, they shoot pretty darn fine in my faster twist gun. The performance on deer is great. I've shot both mulie and whitetail with it & DRT. Perfectly adequate performance when put in the boiler room, and as a plus, hit a mulie in the shoulders & drilled the first, opened up nicely and was found just under the skin after breaking the off shoulder.
It's a sad fact that this bullet is hard to find these days, but I think they can be had through Midway. I'll take the increase in velocity over the 10 to 15 grain heavier bullets, and enjoy the terminal performance all the way to the table.
