2.85" long brass, keep the long neck and blow out the body taper....

fire form using 300 h+h brass.

use the 300 win mag taper and shoulder angle and with this bastard brain child you could use h+h and win mag factory ammo in a pinch and lose i guess 5% performance but gain in fireformed brass to shoot the heavy 220 and 240 grainers

kinda like a long neck stw

compared to the win mag the shoulder would be moved forward .12" with a long neck.

boom

This was done by more than one competitive shooter back when the 300WM first came out. They didn't like the short neck so simply made a long neck version. Weatherby brass was a favorite parent case. Some were trimmed to 2.7 while others were left full length. Called by various names. I believe a long range championship was won with one ca. 1969.

heck with it.....just neck down the .375 Ruger!

The 300 Webbie is the best improved or a 30-8mm Remmie.
The 300 H&H's best attributes are it's slick feeding nature.

thanks for some background cheechako...it would be interesting to see what they came up with...

vap...the easy thing here is forming the cases and the use of some factory ammo and yes the 300 AMERICAN as i have dubbed it would be great.

torque...the webbie is longer and you could use shortened stuff for fire forming. also it has that icky double radious b.s. and the 30 degree shoulder aint bad for feeding but i get your drift...this is more about pushing heavies than the best feeding design.

the capacity will be nearly identical to the 300 wby for performance so getting the bullets into the 3000 fps accuracy velocity range would not be hard. i dunno how fast those 240 gr matchkings go in the wby???

it would be neet to get the 240's @ 2750

I have two of those old wildcats in my collection. One has a longer neck than the other.

You're right about some of the reasoning behind them. Brass could be formed with a standard 300 Win Mag sizing die and empties could be reloaded using any of the 300 Win Mag dies.

Ballistics were not too much better than the straight 300 Win Mag because the only capacity advantage was the little bit gained by being able to seat the heavy bullets in the neck.

But, increased case capacity wasn't the real goal. It was the longer neck.

Ray

this one the shoulder is forward by .12" and keeps the same length neck as the h+h

There ain't no such thing as an "improved" 300 H&H, its just about perfect the way it is..especially with 200 and 220 gr. bullets...

And the winner is Ray! The 300 H&H is a beautiful lady!! The only improvements to her are better powders.

i personnaly think the 300 h&h was a break thru when it came out. but since then, it has been improved upon. the 300 wim mag and weatherby have better balistics and will shoot alot flatter. dont get me wrong, im not attacking the h&h at all. but i wouldnt shoot it on elk due to its low energy level it cant be effective at 300-400 yds on elk as a 300 wim mag or weatherby will be

I did just what you were talking about, left the neck long and blew the body out to .300 WINMAG dimensions. I called it the .300 AT&T (reach out touch someone/thing). My primary use of the rifle was for long range (1000 yard) target. The only problem was, the rifle weighed 14+ lbs and I couldn't hold it up in the prone position for more than 12 shots before my left arm was in agony. Off the bench, the rifle was a true 1/2 minute shooter. I guess I could have used it in "F" Class matches.

in this idea the shoulder would be moved up over .1"

did somebody really post that the 300H&H doesn't have enough MV/ME for elk? 190gr bullet at 3000fps isn't enough? I think I'm having a coronary arrest!

Modified,well yes. improved upon,NO!

BoomS,
I like yer .300HHcat(& .308Norma,&.30x68s) over the 300win,thats for sure.

the 300 h+h base of neck is about 20 thou shorter than the funky double radious weatherby

if you keep the h+h neck placement the same on an improved shoulder angle and blown out body you could probably get 300 wby to chamber and have high velocity factory ammo and cheaper brass to fireform although the wby is 25 thou shorter you would have to shoot it a few times to stretch it.

IMHO, which is just and ONLY! that: the only worthwhile improvement to a 300 H&H is the 300 RUM.

How is improving the 300 H&H an oxymoron? Also, Roy already did it - the 300 WBY.

the wby is a marketing ploy with its double radious...its funky...

i had a 300 wby...if i still had it i would give it proper shoulders

Yeah, I am not a fan of the 300 WBY, or any of the .30 cal rounds. But if I bought a .30 caliber rifle it would be the chambered for the old H&H. Lou

boom stick -

I think that the .300 Weatherby with proper shoulders would be called the .300 Mashburn Imperial. No double radius, just nice 25 degree slope.

If I had a 300 H&H, it would remain a 300 H&H. No mods required.
A fine old round.

Don

the 308 norma mag shoots as hard as the 300 h&h. the 300 h& h would be perfect if the case walls wernt tapered.kinda funny no other caliber has a tapered case?
