Help me answer this question and why

[1shot]

It starts with having several cartridges with the parent cartridge being the identical using the same, primers and bullets (105gr.) indicate at least a good starting point for the proper powder? My examples would be :243 W-W parent case. Derivatives of the parent case, 6 SLR, 6CM, 243 AI and I'm sure there are several more I'm not familiar of. What I'm looking for is that there is a good powder performer across the board, and why that is.

I have never loaded with any other powder for my 6CM's then H1000. I believe by all I have read that for the 6SLR if I shot that cartridge I would use the same, because I've read it works. The .243 AI I do not know about, but would give it a go with H1000.

The range of bullet weights you like to shoot?

The range of bullet weights you like to shoot?

with the cartridges mentioned I figured it would possibly be 105-115 gr. bullets, could be wrong.

Have you looked at QL?

Here is info and a review of QL.

105's only. Sorry, I'll amend the original post.

Hello Don,
I've spent hours on QL and I either I have a parameter wrong or QL is very conservative by default. The 243 AI is a barrel burner by nature so I don't want to use up 30%+ of the barrel life searching for the correct powder.

Lloyd,
there is a long thread that delves into your question, like most threads somewhere along the way it degenerates into pissing contest, but there is some good info there http://forum.accurateshooter.com/index.php?topic=982860.0

Good luck,

Joe

If you will give me these spec's on your rifle/case,
I run QL on my end, with your spec's and see what the results are,
and here is the method I use,

1. Bbl length to the nearest 1/8", with the bolt locked down, run a rod down to the bolt face, then measure the total distance to the rifling edge,
at the muzzle.

2. Case capicity of H2o, using a Fired case, with primer still in place, from your rifle, NOT sized, filled to the top, with a rounded dome,
I use a 15cc syringe and a long needle, horse type, 14ga or larger, about 2-1/2/3" long, tip ground flat,
the water used has a couple of drops of Dawn dish soap added to it, in a large/tall baby food glass bottle.

The Dawn dish soap displaces any bobbles inside the case as it filled, and is easy to add a couple of drops when the case is sitting on the scale.
When finished weighing the case, suck up the water, add back to the baby food bottle for reuse later.

Start with a random decent sample of your cases, (I number each case with fine point marker), weigh each dry case and record the info/case weight,
fill that case, record the info, subtract the dry weight from the filled weight, the end results is the internal case capacity in gr weight of H2o.

3. Total overall LOADED length of the case with the bullet you are using,
4. Brand name of bullet,
5. Total overall case length,

Are you looking for Fps or the most efficient load for the powder/bullet used, or a combo of both?

With the above info, you can set QL spec's to your rifle/case spec's etc and have better results in stage 1 of the accuracy process.
More tweaking within QL can/will produce better end results, for you.

The accuracy quest is another test, down the road. ;D

How "rounded" a dome?

When allowing a dome in the meniscus to form, I can keep adding drops after it barely bulges until it is so bulged as to literally be leaning over one side the the case mouth, like a water balloon. That's a lot of drops and quite a weight range, and it's why I feel "mirror flat" level with the case mouth is better for consistency, but you're not the first QL jockey to stipulate "rounded" meniscus. As good as QL is, that seems like a regrettable source for inconsistent results.

Per the QL manual I received with QL, V2.8 when it first hit the market,
They stated a well rounded dome to over flowing.

I take a paper towel edge a blot up ANY water on the outside of the case, before weighing.

YMMV,

You posted the following info,

1. Bbl length to the nearest 1/8",
28" Broughton and a 31 3/4" Brux.

2. Case capacity of H2o,
237.1 gr. empty, 176.0 full,

3. Total overall LOADED length of the case with the bullet you are using,
2.880"

4. Brand name of bullet,
JLK 105 gr. VLD

5. Total overall case length,
2.880", I think there has been an error made?

Case length and loaded overall length SHOULD NOT be the same!!
unless you are shooting a case I have never seen before,
if this is so, can I buy one for my case collection? ;D

This is a 243 AI case, we are talking about?

Both, the shorted bbl, is on a varmint rifle,
the longer one I shoot mid-range with.

Yeah, there's another nit to pick. Nothing on you, but how can there be a dome and it's overflowing? As soon as it overflows (literally, water runs off) then the surface tension has broken, and the dome is gone. Having a bulging meniscus and "overflowing" are mutually exclusive, in my experience. But, I'm sure QL author can explain it. (Where is he, by the way?)

Don,
I have made the corrections to the parameters


1. Bbl length to the nearest 1/8", with the bolt locked down, run a rod down to the bolt face, then measure the total distance to the rifling edge, 28" Broughton and a 31 3/4" Brux.

2. Case capacity of H20, using a fired case, with primer still in place, from your rifle, NOT sized, filled to the top, with a rounded dome, empty=126.0 gr. Full=237.1 gr. total H2) weight = 61.1 gr.
