Ohen. No. I have not tried any of the lightweight pistol bullets in my Whelans. The only bullets I use are the 250 grain.
From what I understand, you can blame "Slick Willie" for Jensen's downfall. "Butch" Jensen ordered about $2 million worth of AK's and SKS's. About the time they landed in San Francisco, or L.A. (not sure which) our illustrious Pervert in Chief put out his executive order banning the importation of suck nasty little goodies. Jensen's could not pay them, so were bought out by The Arizona Sportsman, a Phoenix based gun dealer. The only reason the jensen name is still on the building, it the Jensen family owns the building, and Butch was guaranteed a job as manager. One thing, the Arizona Sortsman has sure screwed up what was one a great gun store. I've tried ordering stuff, like certain bullets for my rifles, and the refuse to do it. The components shelves are always understocked. Some of the older employees were fired, and from what I understand, most of the current people only get minimum wage, or close to it. Most of these poorly paid "clerks" are ruse as hell, and let you know that they "know it all" and that you are stupid.
I've been a shooter for all practical purposes since I was six years old. Shot my first rifle then, and was hooked. Didn't get to shoot much until I was eleven, but did my book learning. Have worked for a commercial bullet caster and reloaded, a gunsmith, and had a custom reloading business for a while. I feel I have enough exoerience and knowledge that those "clerks" can't snow me to well. I love it when they tell me my Whelan is obsolete, and has no range. That's when I ask them to stand out at 300 yards, and we'll see if it has no range. They sure back down in a hurry.
Anyway, that's the dope on what happened to Jensen's, as I understand it. The name is there, but it ain't Jensen's.
