Re: long neck 300 win mag

I had a 30-338 that was sold due barrel burn out , the 338 win brass is actualy pretty accurate and consistant , just run it through the FL die and their you have it. It has a little less case capacity but I was able to run it up to and past the 300win.
I currently have a 300 Dakota chambered rifle that is an awsome round , good brass and no belt!!

Re: long neck 300 win mag

a 308 bear sound like what you are looking at--it is a long neck 30 cal that can be made from the H&H's or the 300-340 WBY

the 8mag would give a little too much air space and give up a lot of efficieny to the 308 baer.

also Jeff Rogers shoots his special round which is a long neck 300Win.

Re: long neck 300 win mag

D'Arcy,My first concideration in designing my "300 Redneck" was to reduce case capacity,but sadly it only lost 2 gns of water(holds 92gns full with Lapua Brass)..The minium amount of case reforming while getting the required case capacity is the best route...Yours will have more capacity than mine as the neck will be closer to 300 thou..I start forming by pushing the shoulder back with 2 diff dies i made with a 20 deg angle,these 2 dies are used because it's easier on the brass and a lot quicker to get a piece of brass to a shape that is right for competition(less firings) ...Then move the shouler just enough to the final shape with a chamber die to get a crush fit against the new shoulder..Make sure you build a chamber die(7/8x14) the same as the rifle chamber so you can bump the shoulders back as required aswell..Then fire form without a projectile,neck turn the 1st time to approx 1thou total clearance,then neck turn 2nd time to 2.2 thou..This is done with an neck I.D.of.307 thou and the 2.2 spec taken from the driving band dia which is between .0004 and .0005 over an even .308 ..If you are throwing your rounds around huntin and stuff i would suggest more neck tension,i run the minium i can get away with as this reduces the vertical dispersion for me..Hope this helps..JR..Jeff Rogers
