Chicken bullet.

It will be Thursday or Friday before I can post the pic but I will give a range report once I’m done shooting.

Well..... Things didn’t go as well as I had hoped. The groove diameter bullet that I sized to .454 and patched to groove diameter left tons of lead in the bore after only 3 shots. May have stumbled onto something though. A 400 grain dual diameter paper patch bullet seated deep in the case with 45 grains of powder. I will try and test this again Friday

ian45662,

Make sure your wads fit tight if you are seating the bullet "deep" in the case.
If they are loose, then use a lube wad to seal behind the bullet.

Keep on hav'n fun!

Everytime I open my mouth about paper patch, I seem to piss somebody off. THAT IS NOT MY INTENT I AM ONLY ASKING A QUESTION! The question is, how does it lead if it is paper patched? I thought that was one of the big advantages of paper patching--no leading?
Thanks, Cody

Cody, when a paper patched bullet leads it is because the patched failed. In this case, it probably got torn as it when through the throat of the chamber. It can also lead if gas cutting happens. This happens more easily with paper patches which are under groove diameter, of course.

If the patching and bullet/chamber fit is good, then lead never touches the bore, of course. When things go south, however, then leading can be pretty severe.

Cody I will post some pictures later. You will be able see what the problem was.

Ian.

Couple things to look for.
I use the same dia bullet in all my chambers but have no idea what your paper is, chamber is etc.

Things that have caused leading for me.

Inside of case mouth not smoothe
Load not cammed up into rifling
Wasn't careful loading shell and snagged paper on chamber lip.
Proper paper for dia needed ( i wind up at close to .460)

Although im using 12.5-1 alloy i'm also using twice the powder, so guessing lot softer alloy needed)

I use 1 .030 ldpe over 1 .030 veg but again, using twice the powder may have diff results.

Only time i leaded my barrel is when i severly screwed up one of the first three items.

Thank you guys!

I am going to test A few more things tomorrow . After that I will give a full report. What didnt work and what did work (if anything). I will post pictures with it. I have my fingers crossed that a 40 grain charge with a pure lead dual diameter PP will be in the running but we will see.

[BFD]

Based on my experiences, I will predict it won't work. But my experiences have some critical differences. Be interesting to find out.

[ian45662]

Brent it’s a long shot I know but I still really want to try it. I have a few other loads with alloyed bullets to try as well so I’m not putting all my eggs in that basket. I was going to try and cut some chase patches but I ran out of time. I might be able to visit that Sunday or maybe in a few weeks after the long range match in Indiana.

[BFD]

It would be cool if it works but I'd be happy with a 60 gr x 400 gr load.

A couple more things that causes leading with a PP bullet added to the semtave list.
A bullet fired in a standard 45 degree chamber. Note the imprint of a paper ring or maybe even a led ring on the ogive.
I especially deep seated this bullet to see what the effect the 45 degree chamber end has using a PP bullet.
You can see where the case 45 degree pulled lead at midsection of the shank.

Another thing causing lead shooting a PP bullet is using an alloy to hard patched .001" under bore diameter using just one .06" fiber wad.
Also a bullet patched with two wraps less then groove depth in a 45 degree chamber end.

I could list more examples but it just will start a P.....G match. ......Kurt

Yesterday I revisited the DDPP bullet that showed promise earlier in the week. I wasnt able to repeat the group that was shot that day. The bullets we shot Tuesday were 20:1 and with only 45 grains of powder they were not bumping up all the way. IN spite of that a 5 shot group was right around 3" at 200 meters. The bullets only weigh 410 grains so recoil was almost non existent. Because they were not bumping up I decided to try pure lead yesterday. Well..... The didnt work. I tried 40,45,ang 50 grains. I couldnt get them to do anything. I did take 2 of the pure lead projectiles out of their cases and replace them with the 20:1 They were the last 2 of the 40 grain loads I had and those 2 shots were inside 2" at 200. That gives me some hope and so I will revisit the alloyed lead. Maybe tomorrow if I can. Also on Tuesday I tried shooting some greaseres that were sized down and patched to groove diameter. They leaded something terrible. They were 30:1 and as you can see from the picture they just crumpled up. Some paper was even pinched on the bottom band and stayed with the bullet. I fired the first one in the swimming pool then 2 more at 200 meters. The 2 shots on paper were about 2 feet apart and my wiping patch was almost completely covered in lead. I will leave that idea alone for now but I am betting wheel weight lead might fix that......maybe not. The search for an ultra low recoil paper patch chicken load for a 16 twist 45 cal barrel will continue. Maybe I can have something put together by the time I head down to Georgia for the S.E. regional

3" at 200m isn't all bad. Sounds like something you could work on with a bit more powder.

Anyway, here is my new chicken killer (whether it hits them or not ). DDPP weighs in at 308gr in 20-1. Will see how it goes. Like you, hope to have something put together by GA.
