Re: throat angle

Bruce, I am glad to see you adding to the knowledge pool because there is not much we can get out of the law of diminishing returns and we are kicking a thimble full of nuances which of course if you have an inquiring mind are huge because they are there. Peter, that is good to know and something to...

Re: throat angle

Peter, are the polymer tips falling out when manipulated with your fingers for instance? I know securing polymer to a stake can be difficult from when I was experimenting with bullet re-alignment tooling. I am not pushing the Hornady's, although I find them to be a great bullet as have other club me...

Re: Submerging barrels in cleaning solutions

Hey Trev, I would be interested to know, and assuming the Helmar was not contaminated by dipping the jag and patch into the bottle, whether you got anymore blue on the patch having previously cleaned it with Boretech and wiped out?

Re: throat angle

Thank you for posting Frank. Raises lots of little things to think about and how we can bring it back to the topic of throat angles. I wonder if bullet makers take into account the yaw of repose when bullets spin at different rates which alter the yaw of repose with the external force and direction ...

Sound advice Brett. VRA stocks it and you can buy it on the net.

Re: throat angle

G''Day Bruce, I've sat back on this one, but I have reported on Ozfclass before some of my findings using different reamer leade angles in testing I did for NRAA back in 2003 from the machine rest. The angles tested were 1/2, 3/4, 1.15 and 1.30 degrees for Palma. I have subsequently tested out to 3 ...

Re: Abrasive cleaners and copper fouling

Catch 22 with the cleaning and wear. Wal and Bruce are correct with regards to oversize bores and flame cutting and yes some steals are soft. Barrel makers are at the mercy of suppliers. Button barrel makers have to re-heat treat several times and this may eliminate the problem of soft steel. The ri...

Re: Abrasive cleaners and copper fouling

Hi Peter, yes it can but my advice is to use aluminium oxide because it breaks down into a slurry. For other contemplating the effort, don't use silicon carbide or diamond paste. Do use it on a cast lead lap and not on a patch. My preferred method is before a chamber nip and before a minor re-crown ...

Re: Abrasive cleaners and copper fouling

Argh you may have polished her up too much with a good scrub out. Too smooth and copper sticks like plasticene to glass.

Hi Barry, I can rightly speak with experience in brokering the transition from Federal control to State control in Victoria of VRA rifle ranges meeting with the then Defence Minister Moore representing the VRA; and before that for the VRA with the Hamer Liberal government, closely followed the Cain ...

Re: The Future

Well put Barry and Potshot. Live by the sword and you will die by the sword. Our key asset is control of the ranges through rights to them or ownership of some of them. The control won't be lost and this I feel is the sticking point for some with closed minds, if we share those ranges by way of lega...

Re: 300 Winmag and WSM Yes or No

Just adding to Ben's comments about a having an old 30 cal re-chambered and barrel length. Extreme long distance is a class of its own and if you want to be successful Lee unfortunately you have to run with the best gear to be competitive. An old barrel might have to sacrifice valuable inches. But t...

Re: 300 Winmag and WSM Yes or No

Tim is absolutely right about the recoil. Rifle handling and balance cannot be ignored for fine accuracy now demanded in FO at long range. Shooter fatigue is an issue as we age and in long matches. My reamers for 30/378, 300 Win mag and 300 WSM do not get used these days, My 7 SAUM has greater flexi...
