6/21/2023 0 Comments Lyman 450 lube sizer![]() ![]() There was a spell when I had more money than time (have little of either now) and bought cast bullets for several years and TL'd them regardless of the crap that came in the grooves, and eventually got back into casting and pretty much have TL'd almost everything since, except for the odd miscreant gun, and I do still like shooting greasy stuff in my SA 44 Special, even though it's not necessary. Seemed to have worked for many for many years.īear in mind too, that I haven't used the 45s much since the early to mid-nineties either. Maybe if they'd been less worn, they would have been OK. In both, the old brass seal was pretty much shot - you couldn't put ANY pressure on it without more coming out the top than bottom. Some time in the early nineties, I came upon another 45, ordered another "new" piston w/o-rings and it has been fine too. Lyman sold me the "new" version, with the o-rings and it has worked fine since. But I encourage you to try, and report back, if you have success, cuz maybe they have turned the corner? If they haven't, you'll likely find the parts on ebay for pricing that will be shocking.įor what it's worth, about 35 years ago, when I gave up on Lyman dies (indifferent customer service/zero customer service), I also needed a new seal for a 45 I'd bough a few years previous. They've been out of stock on all the popular parts, just like almost every other manufacturer in the gun sports related industry. ![]() I've only heard bad things about getting parts from Lyman. I mean these things could be 60 years old.could have had numerous owners, right? But, it surely is possible that a previous owner, who had multiple lubesizers, could have swapped the new style (o-ring) with the old style (Brass) on your 450. ![]() Since I made the long pictorial post about the Lyman 45 cleanup/disassembly/rebuild, I have had enough conversations with other bullet casters about their 450 and which pressure nut was originally provided by Lyman, that I believe Lyman used the old style Brass ringed pressure nut on early models of the 450. because that higher pressure will start to cause problems with the lube being neatly applied to the bullet. If you don't mind replacing the O-rings when needed, it's probably a better pressure nut, BUT, I have convinced myself, that I like the "ribbon" of lube leaking from the old style pressure nut, as a signal that I have put too much pressure (or too much heat) on the lube and I know to reduce the pressure/heat. The new style with O-rings can become troublesome as the O-rings get worn or torn. First, I will say that I actually prefer the old style Brass ring pressure nut. ![]()
