I think people tend to assign values to some reloading steps inconsistent with actual results.


^This. A small fraction of reloaders I have ever met measure the effects of changes to a single variable let alone record it for subsequent analysis.

Also, the rifle was chambered with a custom reamer so the neck diameter is 0.342" and the base is at minimum SAAMI spec. The brass does not get worked as hard as with a standard chamber.

The rifle groups half MOA using a peep sight.

I anneal to get two - 3 times case life, the accuracy gains are ?? I believe annealing may make old cases more accurate AGAIN after some use use  and it DOES does does ! ------ , but I do not believe I can anneal a new case to better accuracy.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/my-case-prep/#post-3467 https://systemz.online/reloading-methodology/my-case-prep/#post-3464 Thu, 21 Dec 2023 14:22:55 +0000
How often do you reanneal?

I don't anneal yet. I have a gas one and an electric one that i have not used yet.

The bump die's adjustment is the same as most other dies; careful trial and error adjustment of the locking ring. Some would say that 0.003" shoulder bump is excessive, but no difficulty closing the bolt.

As to bushing size; neckwall thickness x 2 + 0.308" - desired neck tension. I tried 0.004, 0.003 and 0.002". Couldn't see a difference in ES/SD so I stayed with 0.002".

As I said, start with good components. Also, it is a .308; not really difficult to reload for.

Lapua brass is quite good as already mentioned.

Berger bullets are very good. Very consistent weight and shape wise. The output from a single machine is one batch. Bullet base-to-ogive measurements are so close as to not be descernable with any of my measuring devices.

I don't mix my cases so I cannot get confused over the amount of times the cases have been used. Only time that I change times-used is when I'm finished with box #12 and start using from box #1. You would think there would be a velocity and POI change between 3x and 4x fired, but if there is it gets lost in the noise from shooting usupported with a sling.

I use fresh powder. Once I open a tin I try to use it all within a few hours. I do not leave it in the hopper between loading sessions. I have found that there can be a significant change in velocity if the powder is left out the tin for more than a day or so depending on humidity and temperature. Whatever is left goes into the recycle tin.

At a guess I would also say leaving the carbon in the case neck helps. I do not have any proof of that except that those that obsessively clean cases spotlessly goes through much more effort with their cases and still stuggle to get low SD figures.


Thank you for the detailed reply.]]> Reloading Methodology DaavG https://systemz.online/reloading-methodology/my-case-prep/#post-2829 https://systemz.online/reloading-methodology/my-case-prep/#post-2828 Tue, 22 Aug 2023 07:14:04 +0000 *****************************
I find this interesting and somewhat worrying, I have also noticed a difference in powder that has stood, even if in a tin (Left over kept for next use scenario).
I started a long time ago with continuously mixing my powders when I buy new powder, I have then found that I can often with just 4 shots know how to go about my reloading.

After nearly 4 years Cody's reloads were depleted, the old batch of propellant was half tin and I had two new tins of S365 that were cooler in burn. A good mix, same load and .4 mm shorter COL had me 2 touching holes and one hole a millimeter off the touching holes - good enough for hunting, even head shots.]]> Reloading Methodology Treeman https://systemz.online/reloading-methodology/my-case-prep/#post-2828 https://systemz.online/reloading-methodology/my-case-prep/#post-2827 Tue, 22 Aug 2023 05:28:51 +0000
