There are also MANY other guys getting the same speed.

Who says its an over the top load?? Duley does
With no evidence whatsoever - no idea on primer, twist, powder NOTHING - however ANOTHER dig at 7mmsaum.
I was speaking to someone that Duley loads for, and it just happens that the load is EXACTLY the same as one of 7mmsaums which he publicly rubbished as being unsafe.
Quite frankly I'm fucking sick of it - its nothing more than character assassination.

I'd take Greg's advice anyday personally he has never put me wrong an is willing to bend over backwards to help, offering advice an experience across the board, in looking forward to meeting him when he helps me with 3 of my Wildcats, has even offered to stay. I can't fault him. Maybe it's tall poppie again:rolleyes:

It's his job, so it's his business to know what's what. Not just a random throwing a load together. . . . . .

Hi guys, I'm now distributing DTA rifles in NZ. See under Premier scopes in commercial advertisers section. Cheers!

Man, some of you guys like getting fired up! Keep it calm or people will lose the point you’re trying to make. If Andrew is loading 2217 to 2950fps out of a 30” barrelled Edge, then that is too hot. Forget whether you believe us or not, the fact is it goes against what Shawn Carlock, arguably the most experienced relaoder and the developer of the Edge says, and who we happen to know very well. If Andrew is getting that velocity and wants to load to it that’s his business, but he should put a disclaimer of some sort with it. If he is the “go to” guy that some of you suggest, then he bears even more of a responsibility to put a disclaimer when quoting a velocity that goes against the norm. If he is using 869 to get that speed, which is universally accepted as being too slow with poor ES and temperature sensitivity and not the correct powder for the 338 Edge, then again, he should say so.
Spanners, we will have to agree to disagree about velocity being a good indication of pressure when trying to work to loading manual loads. But the most experienced reloaders across the world say exactly that, work up loads while carefully watching the velocity. All things being equal, once you reach the book maximum velocity, even if you have not yet reached the maximum powder charge, you will be about max pressure or even possibly slightly above. If you have to exceed the max powder charge to equal the velocity, you most likely have a barrel/chamber with sloppier tolerances and will be at less than the book maximum pressure, or you have a slower batch of powder. That is why it is universally held that velocity is best indicator of pressure, as it takes into account all these other variables. But this only works if you have a reliable chronograph, which is what gets some into trouble. Tussock,that is why it is unwise to just post velocities, so I disagree that is a wise “unwritten rule”. If you are going to quote velocities that are 100fps faster than the norm, then you need to quote your components as well and also a disclaimer.
I will respond to any civil replies, but I’m not interested in getting into a silly slanging match. And I apologise Savage1 if this has hijacked your thread.

Francis - Please point out me to where he said he was using 2217 and thus gives you the right to tell him he is unsafe and going to hurt someone?

The voice of reason !! Good reply Greg

Hate to stay on the topic, but would a bullet seated longer explain higher velocities without exceeding peak pressure?

I believe it is not peak pressure, but the area under the curve as it were, that would result in a higher velocity, so if you someone like SAUM found an accuracy node with the bullet further out than average, he could be naturally experiencing higher velocities, by flattening the pressure curve?

PS: If he had said 3100 I would have said 'its the f1chrony"

(haha)

the extra capacity for slower powder longer preasure is only used in longer barrels and makes more difference in cases of less capacity....I think

Probably, but 300 RUM isnt exactly a small case, and 30 inches isnt exactly short.

Kiwi Greg seems to use this to good effect with 2217 in smaller cases too?

the bigger the case the less the difference it makes...smaller cases makes more difference

Sorry leathel didn't read your post right.

Chris

Wow . 7saum with 16 inch barrel. I think I'm in love , again!

yep some of the boys just gotta swing that tall Poppy sickle

You're not helping


Can everyone chill out, not be personal, and talk about the actual issue

I can see both sides of the argument and they're both somewhat valid

the argument is really just about being safe with what you post on the net and Greg was being safe .I cant see why there is a problem , he clarified what he meant and it was reasonable
