The 1:10's would not do the VLD Baubles I made a while back so don't see how the bore riders would be any different. Soon as I get these 3 uppers done I hope to do some shooting..... if I'm not wheels up by then.....
Loaded up some 247 NOE bore riders and some 180 Lee's. Both loads use 6gr of AA"9 for est 1000 fps. 247's were seated to 1.910" oal and the 180's were at 1.700". Tested chambering in our stock Tokarev chamber and the Lee's hit the rifling hard and will not chamber. The 247's almost went. Going to seat both bullets to the top band and try again. Will verify with QL what this will do to pressures, will definately put them over 1000 fps so charge is going to have to be adjusted down. Also tried each one in our throated 1:8 brl I set up for 240 SMK's. The 247 would go but the 180 would not.
Tok the 1:8 throated barrel out yesterday and got all the 247's to go and a couple of the 180's. Just function test on steel plates, no target work. Using a 7.62x39 AR mag the 247's fed better than the 180's. The 180's are a bit softer and would catch on any edge. Feeding was not perfect and both rounds locked the action back. Going to leave the 1:8 barrel set up together and try and get some more shooting in. Have to do some road work so going to be hit & miss for a bit. Going to look into the mag bodies and followers and see if we can get a good system for these economical boolits
Seated both the NOE 247's and the Lee 180's deeper in the case a dropped powder charge to 5.6gr of AA #9. The 247s are at 1.820" and the 180 is at 1.655" Both rounds chambered in our stock Tokarev barrels. The Lee was into the rifling about .200" but it went. Now to get some range time.....
Since this thread is about casting and cast bullets -- I was thinking about doing some ammo using cast bullets and light powder loads. I wanted to do some loads strictly for plinking. In my case I was planning to go the 22 caliber route and light powder loads. I've got a DI AR in 5.7X28 and tried some really small 30gr cast bullets and 3.5gr of 5744 and the cartridge shot ok but did not operate the action. I wasn't really looking to get the action to operate, I just wanted to see if such a light powder charge would send the bullet down the barrel without getting stuck. The big problem with using an AR for testing is I have to use the charging handle to clear the spent case so I decided to try the same bullet in my bolt action chambered in .222. This time I increased the powder charge to 5.0gr and it fired really nice and the bullet cleared the bore. I don't know if there is any accuracy to speak of with these little bullets and I plan to got to 45gr or 55gr bullets. What I had in mind was a nice little plinking load that was cheap to do and easy to work with. With the light loads the brass really only needs to be neck sized and If I actually start casting my own bullets it should keep the cost down. I was really surprised at some of the light powder charges listed on the web for some of the cast bullets. For a Lyman 45gr cast bullet in the .222, only 7 to 8 grains of Unique is used with the velocity being around 2300fps. I'm not sure that charge would fit in the little 5.7X28 case but it might in the 22 Reed Express that tim is working on.
Here's the new Lee 309 - 230 gr in the center. I posted it in the 300 Blackout page but seeing how its a cast boolit
Just getting the mold started but they came out well running at max temp. Being a Tumble Lube from Lee these things are super simple to run. I'll put a few through the size die to see how they compare to as cast then get out the 1:8 brls. With the generous 5R ogive they should chamber with no issues at all and being used sub sonic, we won't need any super alloy to keep from leading things up.
Tim, Is that Lee lube you mentioned the Lee ALOX? I've been wanting to get into shooting cast bullets and have read some nice stuff about the Lee Alox. If what you are using is the Alox does it dry or does it remain kinda sticky?
Another question: I've been playing with cast bullets in the .225 size. I tried some in my 5.7X28 AR but they were plinker loads and not enough gas to operate the gas system but I was also thinking about the twist rate. The twist in the 5.7 rifle is 1:10 -- would you guys say that's too much for for cast bullets? Another rifle I plan to use is a bolt action in .222 and is a 1:14 twist which I believe is better but those little 5.7X28 cartridges are so small and would make a nice plinking cartridge with cast bullets. I was thinking another choice would be the 22 Reed Express case or the 22TCM case although the 22TCM stuff is spotty to find.

Yes, its the Lee Liquid Alox. Lee developed the tumble lube system and the Alox lube to go with it in his typical KISS style, good enough for 90% of the applications. I've cranked 9mm cast loads to 1400 with zero leading on the Lee 124 gr RN conventional cast bullet with the tumble lube. Here is some more TL info: castboolits.gunloads.com/showthread.php?115418-Tumble-Lube-Non-TL-Bullets The tumble lube is quick and easy plus eliminates the sizing step. Cover the bottom of a plastic container with cast boolits, squirt in some LA, swish around, drop on wax paper to dry. The LA hardens up, but does remain tacky. I thought I had some pics of the 9mm loads, but I don't. I run cast loads in every gun I have from .22 to .50 cal. especially after buying those 240 SMK's As far as the 5.7, the 1:10 should be ok because thats what the 22 TCM uses with the 40gr bullets. FYI, I looked back at my notes and my 22 RE was 1:7 twist so no wonder it didn't like the short stuff.
