If I'm not mistaken, K31s have a 1 in 10.6" twist. I too was hoping to get these Boat-Tailed Gas-Checked bullets to shoot well out to 500 yards. On my next bullet mold I'm hoping to get the weight of my "As Cast" bullets down to between 150-165...

Greetings jasent: I got the Grizzly G4003G Gunsmith 12x36 lathe. The lathe stands that were lost finally showed up but, my brother who was supposed to come by and help me bring it in and set it up didn't show up. In the end I had to...

I'm just guessing but, it looks from the photo that the pulley is just press-fit with a key-way to keep it from spinning loose. HollowPoint

Nothing about cast bullets is etched in stone; although it sometimes seems that way when one reads the replies of the few hardcore traditionalists that will still post from time to time. I've found that there are many different ways to accomplish...

Thank you tweigenant; I appreciate the encouragement. The shipping company called last night to tell me that they found my missing parts. I really don't think they lost them at all. I think that the driver was just angling for a tip on the...

I have a soft-pointing tool that allows me to cast softpoints as quickly as I cast single alloy bullets. In fact, this tool is next on my list of things to do. I plan to upgrade it by integrating a set of 9-12 volt actuators to get an even...

"When I developed a load for my carbine I used my 'test tube' to check for patch fragmentation and one I had found the point it was occurring I loaded up and headed to the range and had a good day. What I look for in the test tube is patch fragments...

I recently sold my Grizzly 9x19 but, while I owned it I used it to re-barrel my Enfield rifle. I had the same problems with threading that you've mentioned. That threading dial was spinning way to fast to be able to get my cutting tool in the same...

My new lathe finally showed up today but, it appears that the freight company (UPS) lost my stands. Now I have a huge and heavy box sitting at the entrance of my carport. I don't want to go down and rent the tools I'll need until the rest of my...

I couldn't say one way or the other. I have very little experience with extended experimentation with paper patching. In my replies, I'm just wondering out loud. The more experienced old hands at paper patching have to be doing something right...

"If you are loading to "normal" cast pressures and velocity the nose rider will work fine. If you are pushing the envelope. full length bullet support works best. A naked nose can and will distort in weird ways causing fliers. I load a 311284, with...

Assuming that we're patching and loading our bullets as uniformly and concentrically as possible, I'm having a hard time imagining how the nose on a Bore-Rider-Style of cast bullet can "Slump" at the nose if it's supported on all sides by the bore...

The bore of my K31 measures .300" exactly. If I can expect the Bore-Riding nose to exhibit even a slight amount of obturation at the higher velocities these bullets will be fired, in my mind this means that at a diameter of .302" I would really...

I was given to believe that the nose of a "Bore-Rider" style of cast bullet is (in theory) centered and supported by by the bore of the barrel. In my mind, this means that if the bullet is cast to the correct diameter without an overly pointed...

Just a short update on the status of this project; I'm still waiting on my new lathe to arrive. In the mean time I've been cleaning up my little 9x19 grizzly lathe. I placed a for-sale ad on craigslist on Friday of last week. I have a guy...

I'm having trouble visualizing some of the written description used to describe the, patch to throat and patch to bore and then the ensuing obturation that occurs with any combination of these important points with a given alloy. What are the...

I would tend to envy anyone who's been at paper patching long enough to be able to definitively deduce the ballistic characteristics of their paper patched bullets just by looking at the fired patches. For a total novice like myself it seems...

I don't really know the answer to the OP's question but, could it be because the .410 isn't as high on the list of popular calibers? It most likely has something to do with "Demand." Generally speaking, "They" won't produce a product unless...

Your questions about the lube-grooves are the same questions I asked myself as I was drawing up this rendering. Initially I thought of just cutting the Cherry with a rough serrated edge in the area where the lube-grooves go. That should have...

This is my initial computer rendering of the type of Paper Patch cast bullet I had in mind. When I finally get around to actually turning the Cherry for this bullet mold I think I'm going to make the nose just a little more pointed; not quite as...

I've heard alot about the subject of "Nose Slump" since I took up bullet casting but, I've never met anyone who's definitively experienced it themselves. That's not to say that "Nose Slump" isn't a real factor when trying to attain high velocity. ...

I'm thinking along the lines of a "Bore-Rider" design with just enough nose to keep the bullet centered in the bore on it's way out of the barrel. Here's another question I've been looking for an answer to with regard to my Paper-Patching bullet...

Greetings CJR: I'd love to be able to get MOA or better from my rifles. If I'd been able to do that the first time around I'd still be paper patching. Since taking up bullet casting I've dreamed of coming up with a lighter weight 30 caliber...

Good news and bad new; if it can really be called "Bad News." I ordered my new Gunsmithing Lathe today. It should be here in a few days. And then it should take a few more days to set it up. Just getting it in the door should be a major...

303Guy: Is there a correlation in the kind of accuracy you've gotten and the way the patch is peeled off of the bullet? It would appear that as long as the patch comes off, it's a good thing; for me anyway. I have done a bit of research on...

I'll google "Paper Patch slow motion" to see if I can track down that video you mentioned. I've already test fired the Boat-Tailed Gas Checks I've eluded to and had absolutely no leading issues. As for gas cutting, I'd have to be able to...

When I purchased the home I'm living in now it came with air conditioning and evaporative cooling. One of the first things I did was take out the AC. We never had AC growing up so I kind of got used to not having it. Only "rich people" had AC...

Hi Green Lizzard: I've tried to picture in my mind the process that takes place as the paper patch peels away from front to back and back to front. With Boat-Tailed bullets, there's a phenomenon that occurs in which the hot gasses from the...
