Yep and that is still the instructions in almost every loading manual I have seen, maybe all. There is one misconception that is almost universally made. That is the maximum load listed in a manual is at maximum pressure. The fact is that may or may not be the actual case. As some have...

I'm a degreed engineer and never worked on the labor side and quite honestly had a bad taste in my mouth about unions from childhood over the way may Dad was treated. I did work for 43 years in design, construction and operation of power plants, sometimes in a union environment but mostly not...

winchester cases weigh about 167gr. Lapua is 173-177 gr. LC is around 180 gr., PMC 185 gr This will give a relative idea of case volume differences. This test was one once fired resized cases trimmed to the same length. Case of a given weight will very in internal volume to some extent...

There is a considerable difference in case capacity of different manufactures for 308/7.62. Winchester in particular is a balloon head design and can have approximately 3 gr additional capacity as compared to heavier brass like Lapua or Lake City. It is important to keep this in mind.

The 28Nosler is a 65 KSI cartridge. You say you have a flattened primer but is it only one or multiple? Have you shot factory rounds in the rifle? If so what did those primers look like? It's possible that the flattening is not a sign of high pressure or it may be an isolated incidence.

What is your COAL?

This proliferation of cartridges designed for the newer ogive (hybrid) bullets is creating a lot of confusion with bullet selection. It is pretty clear the .224 VT was designed around the ARC and maybe the Valkerie. In the 308 there are not a lot of new cartridges but some manufactures have...

Actually Vista Outdoor split the holdings into Revelyst (the Sporting business) and The Kinetic Group (Ammunition) and it was Revelst that sold RCBS liquidating anything firearm related from their portfolio. The Kinetic Group has not been sold off yet.

To be correct Vista Outdoors does not make any powder. They distribute powder just like Hodgdon. It may actually be Federal that does the distribution. Federal is being spun off with the other ammunition companies to the Czechs. Vista Outdoors may be losing the ability to supply powder if...

The first thing you should do is check the volume of the fired/resized brass versus the new unfired brass (Google it). You can also check weight within a lot but with different lots of brass that is not a good measure. It is possible there is enough difference to take you away from your node...

It's possible any or all of the items mentioned can affect your datum dimension. You are overthinkng the whole issue. Setting for 0.002" bump is not going to give you 0.002" every time. If you expect this then you will be disappointed. If you can measure or shoot the difference that +/-0,002"...

The theory behind the concept is valid. Blunt nose projectiles tend to push the shock wave off the projectile while the pointed nose allows the shock wave to attach to the projectile. Any variation in the sharp nose geometry will affect the projectile and likely is an element in dispersion With...

I believe that this occurs when the web page has been up for awhile. I get it from time to time. Refresh and all is well.

The comment related to Lake City is incorrect. Vista Outdoors never ran LC, it was ATK (Who owned what was spun off as Vista Outdoors) who had the contract for a while before Olin Winchester took over in 2020.

I have moderate loss and the muffs with amplification work well with no hearing aids. Most of the in the ear protection I have tried/used does not have enough amplification. Currently use Axil 2.0 so I use both in combination when shooting (steel). Or just the Axil when I'm on RSO duty unless...
