.20 caliber jackets
Pat,
I can't properly answer your question but since no one else has responded, I can provide some related information. I have made .204 bullets in the VLD point style with a FLAT base in weights ranging from 38 grains to 47 grains using jackets drawn from .224 jackets. I used .224 jackets that were .640" long as received and were .698" long after drawing to .204 diameter. While changing the core size will let you vary the finished weight within certain limits, in my experience the weight range mentioned above is approximately the weight range available with this jacket - the jacket is nearly full of lead to the tip at approximately 47 grains. The weight range that is practical with a given jacket length will vary depending on the point style (and probably the maker of the die). It will also be affected by the base style. Not having made any boat tail bullets, I cannot estimate what effect this will have on the finished bullet weight and / or the jacket length required to obtain your desired finished weight. For these reasons, I cannot tell you what jacket length to buy. The only place I have purchased jackets is from Berger / J4. Following is a link to their jacket listing: http://www.bergerbullets.com/jackets.htm . I am not sure that this listing is current; when I called to order bullet jackets I was told that one of the jacket lengths listed on this site had been discontinued. I am not sure if it was one of the .172 or .224 jackets however. Sierra's web site shows no stock on bullet jackets; http://www.sierrabullets.com/index.c...bullet_jackets For whatever it is worth (probably very little!), if I were ordering jackets for the bullet you mentioned, I would probably order .224 jackets in the .705" or the .740" length. If your bullet maker has a jacket trimming die in either .224 or .204 diameter you can always buy the jackets on the long side and have him trim them to the needed length either before (if using the .224 trimmer) or after (if using the .204 trimmer) drawing the jackets. I know this doesn't answer your question but perhaps the above information will be of some help. Good luck, Gary Last edited by Gary in Illinois; 01-04-2007 at 10:50 AM. |

That's a good answer, Gary....
With a bullet jacket longer than needed/wanted for the finished bullet, and a jacket trimmer, you can make any weight/length bullet you want to make that will probably shoot well through the barrel twist you're working with if the end result/bullet is not too long.
If you make it too, long, the proof will be in the pudding when you try to make it shoot good........and it won't.. -BCB

I bought some Sierra .224" jackets about a month ago. They didn't show to be in stock on their web site, but they had them in stock when I called.
Try a call to one of their Tech Specialists, and they will connect you with the "jacket lady"..... I especially like the Sierra jackets for making 20 caliber PD bullets. -BCB

Gary- thanks heaps - its been a while since I checked this post and I must have missed you excellent reply.
My bullet maker is so busy making established BR and other Comp projectiles ATM. That he's putting all "special" orders on the back burner. Will need to give a set of forming dies to a Tool maker who i used to work with to see what he can do about replicating them but in .204 cal and .172 as with the new fireball coming out there is intrest in that over this side of the pond. So things are moving but not quite as fast as I wanted. I'll email him a copy of your post and see if he has a trimmer. Thanks again later p |

Do a search for Corbins too.
They're the originators as I understand it. They also sell the .22LR jacket forming dies. but, their price's will scare you. Might be you can get the design and pass it along to your local machinist and he can make them for you. Wish you the best, let us know what you come up with and how it works out.

If you are having problems getting jackets and your bullet maker is telling you that you are on the back burner give me a call. Maybe I can help you get your jackets without buying any equipment. Drew (231) 229 4529 |
