300 Wheeler

[rhovee]

Took her out to 600. Had some mirage but got a nice group. I’ll take it to Deep Creek in a few weeks and try 1000.

Rhovee, any updates on your new pet, looks to be a great alternative for the shooters wishing to tool up for a big 30! I'm a fan..

I switched things up to N570. Threw a cold bore plus two follow up shots at 100. Then took it to 600. She is ready to go!

Nice work rhovee!! Have you tried squeezing a 215gn pill down the tube to see what sort of V0 you might be able to achieve?

I ordered a pair of 338 RUM reamers the day my Shooting Times magazine arrived introducing the new case and its .090" reduced length. I have a 30/338 RUM and a 7/338 RUM. My reamers were made Feb 2002. I just got in the ADG brass as well and am looking forward to trying it out. I also cut down a Redding 300 RUM FL die. The 7mm version is what I built first, and healthy doses of IMR 7828 with 140 Accubonds was running 3650 fps. It is an antelopes worst nightmare.

Alex Wheeler and myself have done quite a few projects over the years. I had the first 300 Norma improved barrel for testing/shooting. While it's a great case, there is not many good action choices for the Lapua sized cases. The other down fall, is not many re-barrel choices out there. We set out to find what would be the max case you can run with a magnum action, and still be able to feed in a CFE-9 (4") BDL.

The 404 Jeffery is a very accurate parent case. Think RUM, SAUM,WSM ETC. The 300 RUM is one bad dude! Only issue that I have is the case is to long for the 230 Bergers to fit in the neck. The 338 RUM is .094" shorter than a 300 RUM. I took a 338 RUM case, (109.6 GR VOLUME) necked it down, and could seat a 230 in the neck with .050 above the dreaded doughnut. This put the case at 3.950. This freebore will also work well with 210VLD and 199 Hammer Hunters.

Necking down the brass is very easy. I purchased a Hornady ($32) .308 neck sizing die. Sized the necks, then ran an expander mandrel though to set my .002 Neck tension. For the dies, I took a 300 RUM die, cut .095" off and it sizes the web like a custom die should! No custom dies is a plus!

Next I loaded up some 230's with H1000. After about 40 rounds, I started load development. Out of the gate I could tell this combo would work. 89.5-90.5 all had same POI at 300 yards. I took the gun to 300 for some grouping. 89.5 grains has produced 1.2"-.75" groups multiple times. This load has an ES of 9 FPS across 12 shots on different days. With a 26" barrel the 230's are 2 grains below max, and are going 3040 FPS.

I am REALLY liking this cartridge. It feeds great out of my BAT HR, Loves H1000, ADG Brass. IMO this is the best option for guys wanting 300 NMI speeds out of standard magnum actions. Once you fight doughnuts and seating the bullet below neck shoulder junction, you won't want to do it again..

What an awesome idea, can't believe no one ever thought of it before. You both will be billionaires after this! Lol

Wait until you get your next bill, that should help!

 

[rhovee]

Thanks Tom.

 

[Alex Wheeler]

Thanks Tom.

Tom's not messing with you. He saw an opportunity to stir the pot. It's kind of an inside joke, anytime a post like yours pops up a bunch of guys have to post who did it before you even though you didn't claim to be first. When maybe they should be encouraging a young shooters first try at messing with cartridge design. Its like when someone shoots a record, someone always has to post how they have never seen such good conditions. Its funny.

You should have named it the 3 wheeler!

 

[rhovee]

That’s it. Official name change. 3 wheeler it is!

 

[Alex Wheeler]

The problem with naming stuff weird names is no one knows what the cartridge is. You can go down these pages and see quite a few threads for load data on my different improved cartridges. I always name them what they are so people can search for the data. 300 Norma improved, 338 Lapua improved, 300 saum improved, ext.

Any new info or pics in the 3 years since the last post in this thread?
Thanks

 

[Alex Wheeler]

Theres not a lot of these out there. It duplicates my 300 Norma Imp 35. A lot of guys use my Norma imp design, if your using a die from Bullet central your using my chamber design no matter what the builder calls "his" chambering. The load data for the Norma imp is the same as this cartridge. They will tune up within less than a grain of powder. So you can just look at 300 NMI 35 degree load data to get close. I did chamber one up for Broz over on long range only recently. Thats another place for good info on this kind of cartridge. Probably the best place for the long range hunting type stuff.

Here is a picture of the case for reference.

Somethings not right about the 2nd from left. NOT a 30 cal for sure.

Thanks for the response.
The reason I ask, is because I don’t have a Lapua bolt face action.
And thanks, I did read the article/thread over on LRO.
