Well shoebox, i have to admit I never considered the chamber as the problem...cause I shoot a Savage. Be that as it may, i guess you are correct in your approach, especially on Remingtons and Tikka. I might mention that here in the Northeast such an approach might be a little loud for the neighbors next door, but then they have witnessed my acetylene oxygen pigeon chasing balloons, so it might not surprise them.Man this is good stuff, I will add it to my techniques manual, so just a question or two, I'm so excited I don't no what to ask first, OK important stuff first !!
What breed of chicken - age of bird - left or right leg, I notice you said properly season , I don't want to infringe
But could you tell me seasoning type/types, weight's and application procedure, also straight drive or rotational reaming, be assured this info will be for my eyes only!
This will tighten that 900 yrd group !!!
I'm not sure if a man with your highly technical approach, would consider a layman method, but here goes, as you stated the die is the weak point, so i rarely use them, most people fire form brass, they are missing the point
"fire form the chamber"
Yes I know it's so obvious !! Quick run through of process
First measure OD of chamber ,
Acquirer a bullet one caliber larger than bore heavier the better ie 257 - 264 this allows required gas seal !
Prime with hottest mag primer you can get! Fill case with blue dot or similar fast powder
In my case 93 grn then compress hammer and 1/4" drill for my particular applications be careful not to damage neck, compress - fill - compress- fill I get 115.6 grain in with slight case bulge
Recompress when seating bullet
Load bullet in chamber if all is going well you will need rubber mallet will only take 6-10 good stiff strikes to close, hey ready to go !!
Go out the back and squeeze of a shot
Believe me this will straighten out everything, (oh ear protection safety first )
Now unload may need mallet again?
Check for primer, if any sign of primer is found start process a gain !!!
Measure OD of chamber 2-3 mm expansion is standard, 3 -4.5 mm is much desired
If you are really pedantic you could recontour chamber but the barrel may take a bit of getting out
So now you have a chamber that is dead straight no need for dies, fireform and a light crimp
Concentricity what so hard about that !!
Your results may vary ?
Given my locale, i have to stick with the chicken bone hone. It tends to go over with the neighbors and I even invite them now and then to bring their own and help me find the perfect hone.
First you need the right chicken bone. I generally find my best specimins in my second dozen plate of wings (side beverage included). I use the short part of the chicken wing bone that looks like a little drumstick for the larger calibers, and the bow shaped bone from the flat part of the wing for the sub calibers. Any chicken that is dead will do, cause it is the mythical wing bone that matters most. Now here is the key...aging. Yep, that is right. It doesn't matter how old the chicken...it is how old the bone...from the point it has been DEEP fried. (Baked, microwaved or grilled softens the bones in an irregular fashion). About twenty minutes after deep frying, and soaking in ANCHOR BAR (Or Sweet baby Rays) Original Buffalo Wing sauce seasoning, you have to carefully remove all the meat and get all the soft parts off. Then you take that bone and carefully smooth it with your teeth. Ya, I know, primitive, but it is an art. Work at this...really.
After getting all the soft off, put it on a paper plate, lean back in your chair and sleep it off while that bone hardens overnight. If outside beware of racoons.
next morning, grab the bones, your JB paste and just slather JB on the bone. Hone the inside of that bushing, cutting back the sharp edges and if it is a Redding, make sure you get all the slant out of it, using a rotational straight push and pull. You will get the knack of it. Soon your bushing will be perfect and then it will work perfectly with your perfect brass. You can, if you choose, get a concentrating gauge, but i have found that most of them require more antacid than the wing process.
keep in mind that these techniques are for advanced handloaders and adults only. Children should not participate in the creation or selection of the proper chicken bone hone. But if you have a really bad bushing, you might find that having the kid practice on it with a pre-selected and prepared bone will keep him busy and will start him early on the pursuit of the pineapple of precision handloading.
BTW, you might want to modify one of those hydraulic case forming systems to compress your powder. Thinking about your technique, I see some safety issues. When using a hammer you always risk missing and hitting your thumb.
here's to innovation and the internet!
