I need a new Postell mold

[bruce m]

zack,
you will find that when a good pp load evolves, it is akin to arriving in the land of milk and honey.
doubly so when you get the airgap right breech seating.
keep safe,

A 43, isn't anyone interested in what Dave used to shoot the match winning 43 ?

[SgtDog0311]

A Ballard )

[desert deuce]

A Ballard, I see......let me guess? (Have to employ some globalist thinking here. )

Hmmm, .44 caliber patched pure lead round ball over 8 grains of bullseye maybe ? Using a primed UMC case, drop powder from muzzle using a gyroscopically centered brass tube 37.221 inches long & two thumps on the rim of the muzzle to settle powder, insert bore buttered patches and ball 3.1 inches from mouth of case? Close ?

Or maybe an old Scheutzen favorite, Lyman 375248, taracorp range scrap, pan lubed with white lard, 18.0 grains of SR-4759, Rem 2 1/2 Primer, CIL Case with a very light taper crimp? That's not it...

I give up.

[Don McDowell]

I heard he was shooting an IAB that had been rebarreled with a Numerich barrel, shooting a 460 gr beer keg bullet, using free chex stamped from Miller lite cans, with a powder charge of wc870 surplus powder...

[DeadEye]

Don,

You forgot the Over Primer Wad. It's an idea he picked up from Mr. Gazaway. They use Cheerios dropped in the bottom of the case. Doug found that the hole in the Cheerio helped the primer propagate the flame better. I have not tried it yet myself as I'm still trying to figure a way to index the Cheerios.

you stay well now,

Paul

[Don McDowell]

Paul we weren't supposed to let that secret out.
You too Paul, and give our best to Ms. Spot

[Kurt]

what has this turned into??

[desert deuce]

You know Donny Ray, that makes sense from an intelligence point of view.

Pretty sure I saw a Numrich Arms Parts Catalog on JRV's dashboard at Raton last August and Dave was talking about Chex Checks. I didn't think to tell him I have a Chex Check Cutter and pilot so it was probably another Lyman or Lee gas check mould he was using at the Q. However, I would think being that they live so close to Canada, that the favored can material would be of Moose Head origin

Hope this doesn't give Gunlaker or DeadEye any ideas.

[art ruggiero]

i thought the cheerios were to take up volume in the cases for reduced chicken loads art

Actually that's been done already up here because it was difficult to get Hornady gas checks for a while .

Although this Postell stuff is entertaining, for the moment I'm sticking to an old fashioned big lube groove Money bullet in my new .45-2.4".

So far so good, I'm developing a load at warp speed for this new lead slinger. First target at 300 yards, if centered, would have been a 100-7x on the reduced 600 yard target. Fifteen shot SD at 3.6 fps. When I first got the rifle it was doing a solid 6 moa at 220 yards. Annealing the necks very soft made all of the difference in the world.

Now all I need to do is hope that it holds up at 1000 and not loose my shXt and start jerking the trigger.

DD, are you bringing a shiny new Postell mold to Phoenix?

Chris.

chris,
can you put a number on "warp speed"?
keep safe,
bruce.

[gunlaker]

Sure Bruce .

I got the rifle in the second week of December and started fire-forming 200 pieces of brass. I shot a number of different bullets and powders through it with miserable results. The first hint of goodness was on Jan 4th when it put 8 of 10 into 2.3" at 220 yards, there were two unexplained flyers likely caused by errors in prone technique. This was using the 459530M4 bullet which is excellent in my .45-70. Try as I might, I was unable to duplicate these results after a number of attempts. It turns out that the brass was really hard. I annealed the necks until they were quite soft which improved things quite a bit, but not enough.

I then switched bullets to the 458535M which works very well in my .45-110. As long as the cases have been shot more than once, and has the necks annealed to be quite soft then this load shoots very well at 220 yards. It's been tested a number of times at that distance and is quite consistent.

Today I took it out to 300 yards and it held up quite nicely. It took 2 shots to settle in and then put the next 13 shots into 3" of vertical (more horizontal though).

Velocity stats are good with a 15 shot average of 1343 fps and SD of 3.6 fps so it SHOULD hold vertical quite well.

I've been working at it pretty frantically as the winter days here are rainy or snowy, dark, and gloomy. Often the range is fogged out, and even if it's clear, sometimes there is absolutely no wind. A few times I've had to stop after less than 10 shots as the smoke hangs in the air so thickly that you can't see at all.

One day I thought I was going to be lynched by a bunch of benchrest shooters trying to print bug holes at 300. They were none too impressed by my Sharps fog making machine

I've got 35 pieces of brass left to form, and I'd like to shoot this load at 300 a half dozen days or so, weather and light permitting.

Chris.

chris,
your experience with annealing reflects my own.
nowadays i anneal bpcr case a little softer than for smokeless rifle.
this is easily done with a machine and tempilaq, giving consistent results.
also having very fireformed cases helps accuracy, particularly as the ranges get longer.
soft annealing can come with problems if you use heavy compression, namely rounds can become difficult to chamber.
but this can be dealt with by not compressing any more than necessary.
1 moa vert at 300 will probably become greater moa at longer distance, but an s.d. like you have will minimize it as much as is humanly possible.
i have noticed you use a significant number of shots to establish s.d. numbers, unlike many people who kid themselves with low shot numbers.
oh to have those no wid conditions for testing like you.
the disadvantage of no wind is you can get a little more vert due to the target image going up and down relative to is real position, but not necessarily.
good luck in your endeavour.
you deserve it for all the work you do.
but then that is the journey and the journey is most of it.
keep safe,
bruce.
