I shoot the .58 in a T/C/ Firehawk and they are definitely the most accurate conical I have shot in that rifle. I recently ordered the .50's to try in my Lyman Mustang. I will let you know how they shoot.
I just got the bullets in Monday. They shot very well with 80 grs of 777. But because of the corn I was limited to 40 yards. But I was impressed anyway with the accuracy. 1" group and I believe that it would have been a lot better if I would have taken the time to get a proper rest.
I will more than likely take these out this year to hunt, but to be honest I wish they were a little heavier... around 300 gr. My son is going to take my .58 out with the B.W.V and that is where these bullets really make the difference. These are devastating to say the least.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
