Once upon a time Widener's sent me some ammo, and I told you I'd do some tests. Due to various things, including me forgetting things*, it's taken a while, but here's the first.
Winchester .45-70 Ballistic Silvertip
This is a 300-grain polymer-tipped bullet, and it's a screamer: muzzle velocity 1880, energy 2354; they roar at both ends of the rifle.
I fired a group of five out of a Pedersoli Sharps a while back; group was definitely 'put meat on the table' for deer or bear at 100 yards, but nothing to write home about. Which isn't saying bad accuracy for the ammo; I've read a number of people saying that their rifle of that type won't shoot bullets of this weight & length real well. So for this I had a chance to put a few through a Marlin 1895. This was at 30 yards on an indoor range, with a caveat: the ventilation system on that lane was causing the target to blow some, so I was having to time my shot with when the damn thing was where it was supposed to be
*As in I did shoot some handgun ammo(Federal .38 Special target), and I can't find the pictures I took; assuming I can, I'll do a post on that .
