300 Wildcat

If one was to remove the belt from a 300 Win mag case what would the cartridge be called and what brass would be used to make this cartridge? Is there any benefits to building a cartridge like this compared to a regular 300 Win mag or a 300 short mag?
 
I don't see much of an advantage except you could size the belt area without a belt. I personally don't like belts. They serve no purpose. I like the WSM case. Almost as much velocity with less powder.

In competition it has been winning and setting records. Very big nodes and easy to tune. Made all the other Magnum cartridges disappear on the firing line at 1000 yard BR. The brass is really good and the throat wear is way less. Matt

Howdy !

Closest case specs to match the new wildcat's new "beltless " base diam, would all be Euro-spec stuff.

Such as: 8 X 68S, 9.3 X 64, 6.5 X 68 Schuler. 10.75 X 68; and perhaps .350 Rigby rimless.

Not exact matches, vu tpretty close on base diam and case oal's.

Rim diameter is another question.


With regards,
357Mag
 
I don't understand what that responds has to do with, headspacing off the shoulder rather than the belt.
And that you get 25 firings out of your brass, I wouldn't want to I have a different objective for my brass, and that objective is to mutilate it in the lease amount of firings as possible. That way I know I have extracted the most amount
of energy from every firing which usually equals about 5 firings. As far my shooting goes, hey I take no prisoners and will not give up till the brass cries uncle.

Op . You can remove the belt from the brass and have the reamer belt removed also . It takes a lot more to actually do safely than just grabbing brass and chucking it up in a lathe . Much more than can be reasonably and safely be put on the web .
There was a well known smith , shooter that removed the 6.5 rem mag belt and had a reamer made to match it , but like was previously said , use the shoulder as your headspace .
Fireform NEW brass with either a double diam neck or bullet seated out to the lands ( jammed ) . Proceed with caution if you've never done this .
 
This approach stems from my race engine building days, where you extract everything you can from what you have to work with. That has obviously transferred over to my shooting style.

Dkhunt14 and most others on this site including myself try to get the most accuracy from any given cartridge. We could trash brass in 5 firings but we're looking for actual accuracy. Im talkin about higher bc bullets carrying more energy and better terminal performance on game or targets. Its cool to have an über mag shooting 5000fps but if you cant hit a groundhog every shot at 1000yds or even be able to have the bullet make it that far is pretty much useless to anybody except the chronograph betters.
 
A Major misconception is you can't have accuracy with speed that is not true, my most accurate loads hover around 95% of my max fps.
I am really curious about one thing, of the 30 thousand plus members on this forum. What percent of them would you say can hit a ground hog at 1000 yards in real life conditions. I am not talking on a bench with micro adjustable rest and a high buck high powered scope staring at a 10X ring. I am talking out in the field having to re position every time the chuck moves, not really knowing they exact distance basically all the factors that come in to play.

Ive never seen anybody win a match much less shoot in one with say a 300ultra mag, 17tw barrel and 125gr bullets. Physics concerning BC holds true whether its a gong target, groundhawg or paper and a higher bc translates into better hit percentages. Add 100more gr to that bullet and put it into a calculator at long range and see the stats

Most of the groundhog hunters I know sit and glass. They set up a bench and shoot. I have a couple places,where I can reach to 2000 yards. I have shot lots of them at 1000 to 1200 yards. A groundhog under 500 is no contest. Most of my guns will 5 shots in the 5 inch range at 1000 yards. I know hundreds of guys that hunt that way. I believe in accuracy. Matt

Dean,
Some of the forum members here tend to be a little narrow minded when it comes to cartridge selection and the accuracy requirements thereof. If we took these comments and recommendations as gospel, we would all be shooting only 6mmDasher, 284 Win, 300 WSM cartridges. I read comments all the time about short barrel life, overbored cartridges wasting powder, etc. I am just happy we can shoot.

We live in a free country, at least for now, and we can do as we like. There is absolutely nothing wrong with the 300 Win Mag cartridge, or any other cartridge, belted or not. Some cartridges may perform a very specific task better than others, but to each his own. In my magnums, I don't concern myself too much with brass life as I hunt with them. 1-3 firing is realistic brass life as I lose them first.

Instead of going the route you're talking have you thought about just doing a different chambering, if I recall correctly the 30 BooBoo is just a bit more thab the Win Mag, uses RWS brass, there's forming but I'd think it'd be easier than rim trimming.
 
Not all my wildcats are slow twist that only shoot light bullets, you can have your cake and eat it to. I have several that shoot heavy high BC bullets that would be more than competitive, there just not as fun.

22-06 AI 80gr bergers 4000+fps


6-06AI, 3800+fps 6WSM, 6MachIV, 6RUM all 105 Amax's 4000+fps


6.5Rum 140s sierra's 4000+fps

I would build a 30 Nosler or a 300 RUM for hunting or fun. For competition or ultralight hunting, build a 300WSM. Not belts on any of them.

Would you be so kind as to name the seven cartridges in the 2nd picture
 
From left to right

1st 6BR I also have a BRX but have been to lazy to form any.LOL
2nd 243 AI
3rd 6mm X 55 Swede
4th 6-06 AI
5th 6mm WSM
6th 6mm Mach IV 7 RemMag necked down to 6mm with a sharper shoulder
7th 6mm Remington Ultra Mag

Dean
 
A 30/375 SI. An Ackleyized 375 Ruger necked down to 30 Cal.

I built a 30-375 Ruger, about 3-4 years ago, and like it but if I did it again I would do a 30 Nosler as I think Nosler brass is better than Hornady's 375 Ruger, no necking down from 375 in step, and dies are available. The difference in case volume is not large and the Nosler brass wins out by a smidgen.
