Heavy Guns

[macca]

Okay, looking at aJR's plans for a new LG and given the bug bit me at Canberra 1K, I'm thinking about a HG.(God help me financing this but!!!!!!!!)
I know bugger all about them other then they come in a multidude of stocks and calibers.
First I looked at;
7mm/300 Boo Boo
7mm/300 Rednecks
300win/300winAI
300/338L
Please step in and correct me anywhere I go wrong.
The Boo Boo's are on the 8x68 case(.510 rim - 86 gr H2O??),the rednecks on the 9.3 x62(.470/.476 rim - ?H2O).
Which case is better in terms of capacity and available good brass.
What configuration of stock and actual weight do you need to be competitive.
Will a 3/4 inch stock on a well balanced rifle be at too much of a disadvantage to the 45lb guns.
Would a muzzlebrake be useful to help a lighter rifle.(I know it wouldn't be useable in Fly).
I'm a bit lost with the how to start with this one(too little expierence in this field).
Any and all advice appreciated.
Thanks,
Macca

Grant, the Rednecks are based off 300 Win Mag cases. 360 thou long neck and 35 degree shoulder. 90 to 92 grains h2o capacity depending on which case is used.

Macca,

The Redneck as Tony said is the 300WM case the Boo Boo is the 8x68s which is available from Norma & RWS although I think the general concenus is that the RWS is better.
300WM is available from Lapua. The 9.3 x 62 I think you were looking at is the 30 Jat and brass available is Lapua.
I have an ugly (well not really) old stock for a HG that I could part with for a small amount of money to get you started .. pm me if you wish to discuss same.

You seem to have omitted the 300 ackley ??? and 300WSM amongst others is that a short list or are you still looking for options ?

cheers

[macca]

Thanks,

Gday Macca,
Mate the rounds that have been mentioned will all work well for a HG.

Sometimes its best to work out what is easiest to get hold of component wise and at a resonable price and go that way unless you get your heart set on a particular round.

I myself wouldnt worry about a muzzle brake on a heavy gun, simply because if you build a HG make it a HG with plenty of weight. Otherwise it defeats the purpose a bit.

The stock of a HG is very important, it needs to track well, hold plenty of weight and give balance and handle torque well.

Oh another round to add to the mix, 300 yogi (30/338 lapua AI) very nice.
cheers,
Shane

Macca , There is a real small # of plumbers in AUS that know anything apart from what they read about H/G technology .. So if you can't do the work your self then pick him ( down your way i might add ) and run with his recomendations.. The only good advise i can give is once a cartridge is picked ,do you very best research to get a large quantity of bullets(atleast 2000) "that are worth owning", without great bullets you have an upill battle.. ..JR..Jeff Rogers................ps muzzle brakes have always been out for H/G in AUS

Thanks Jeff, I was going to start asking about which projectiles next .I had read some of your threads on this and thanks for the advice you gave in them.

as a supplement to the excellent advice you can attain on this site, i would also recommend that you contact some of the american 1000yd br shooters.
ie (on http://www.benchrest.com" onclick="window.open(this.href);return false;, http://www.6mmbr.com" onclick="window.open(this.href);return false;, http://www.long-range.com" onclick="window.open(this.href);return false;)

i have found over the years that they are most helpful and willing to share their knowledge and experiences in many areas.- equipment, shooting techniques,shooting conditions,rules etc.

quite a few, have have shown a genuine interest and are well aware of the developments in australian 1000yd br over the years.

cheers
