Gerard,

You still have not answered the central question here.

Both Alf and myself have specifically questioned whether the load that produced 2900 fps with the 265 gr HV bullet is a safe load, and how it relates to the CIP maximum. Quickload indicates a gross over stepping of the CIP spec. That was the concern, but you have elected not to answer it. The only conclusion is then that you seemingly condone it after repetitive questioning. You much rather prefer to go into a rage and a personal attack. Hot loads and max loads seems to be a very elusive thing if we cannot agree on some kind of a generally accepted standard.

You demand that I answer your questions but ignore the ones I ask. When cornered, you raise another imaginary issue and so it carries on. I am done with you and will only point out your mistakes from here on.

We do not reccommend magnum primers for speed, we recommend magnum primers for the additional initial pressure they generate. This starts the bullet earlier and artificially creates a bigger volume for when powder starts burning. The further out the bullet is, when powder starts burning, the lower the pressure and the more powder can be used to drive the bullet while remaining within pressure limits.



Switching from standard primers to magnum primers will invariably increase pressure. In the A-Square tests, the pressure spread between the CCI 200 and the hottest standard primer (the WLR) was 9600 psi. The spread between the mildest magnum primer (the Rem. 9 1/2M) and the hottest magnum primer (WLRM) was 8300 psi. These are significant pressure variations that cannot safely be disregarded. So the point remains to have a blanket policy of using magnum primers regardless of caliber, will have pressure implications, and if not pressure tested could push one over a save limit. When coupled with an already hot load, it is bound to push one over the CIP standard, and that may well be the case with the bullet/load combination that are being discussed here.

We have seen in our 9,3 test loads an increase in 100 fps, and that means increased pressure. Whilst it seem insignificant on its own, it might not be when one is already above a save pressure position. The pressure differences that A-Square highlighted cannot just be brushed aside as a non event.

Just to highlight once again, what we dicuss here is not about faults with GSC bullets as you try to make out, it is about reloading practices. Please concentrate Gerard.

Only if you switch primers after a load has been established with another primer. It seems you are ignorant of the rule that says: "When any component is changed, drop the powder charge and work up again." But then you are ignorant of so many things, this is not surprising.

I am beginning to believe that bullets fly faster at lower pressures in Port Elizabeth than anywhere else in the world. Wink

It is quite possible you would believe that. There are a number of even more absurd things you hold up as truth but you lie so much, who knows?

Then a recommendation of 74gr of RL-15 as a start? each and every load manual puts this load as actually over limit for the SAAMI pressure cieling for the H&H and the projected velocity of 2900 fps would be way over the pressure limit !


Gerard,

You are so full of compliments. It is not only QuickLoad that rings the alarm bells. As Alf says, "each and every load manual puts this load as actually over limit for the SAAMI pressure cieling for the H&H and the projected velocity of 2900 fps would be way over the pressure limit!"

You still have not responded to this question, but create so much smoke here that the you have fogotten to answer the question. Gerard, you are losing your focus again.

In your ongoing effort to find imaginary fault with GSC bullets, you only read half of the stuff. Half pages, half paragraphs, half sentences and maybe even half words. After Alf posted that, I asked where he found manuals with drive band bullet data. Like you, he fails to answer the questions I ask. Go harras someone else with real problems instead of dreaming up stuff about GSC when you smoke your socks at night.

Gerard,

The fault does not lie with the bullets. Be clear on that.
We discuss pressure dynamics in reloading practices.
Just have your say on the matter and quit creating smoke.

At last, a photo of the Kudu bull mentioned in the beginning of this thread.
Apologies for low quality of photo, it was taken with an ordinary film camera, printed and then scanned onto a CD - looonngg process!


Hunter on photo: PH Henk Blignaut.
(BTW Henk is 6' 4" tall and weighs 150 kg.)

Excellent illustration of the Boddington Technique of photography.
The "Trophy Lad" in the foreground weighs about 40 Kg yet dwarfs the 150 Kg PH in the background. Wink

Very nice Kudu.

I want to try the .395/340-grain GSC HV on Kudu. thumb

No doubt the GSC bullets are as good as it gets.
