NEW cartridge !!!
 
Yall remember you heard it here from ME first. I'm going to design a new cartridge or 3 by necking down the .375 ruger case to 7mm,30,or 6.5mm.
I feel this will make a outstanding round with substantial increase over 7mm rem or 300 win while staying within standard length action. Let's have a vote to see what yall think I orta build 1st. I'm kinda partial to 7mm diameter bullets myself.

Have you done any ballistics analysis on the bullets listed yet? Some of them sound like they'd have really 'humpy' ballisitics and odd terminal ballistics.

375 Ruger
 
I think there is room for one more fabulous 7 , good choice, wildcating the wildcat, well, you got to start somewhere!!! You should start a thread about what to name it, weather it lives or dies it will need a name, a little input never hurts. good luck.

re: new cartridge
 
Matt,I've only ran sierra infinity ballistics and create cartridge programs. I'm going to send dummy cartridge to have reamer made in next few days.
Rickrem,your correct that marketing is everything in today's shooting world.
I'm not naive enough to expect to make money off this,just want a useful cartridge. I've experimented in past thruout the past 27 years all the way up to .416 rigby cases necked down before among others. :D

You should call it the 7mm SOCOM. You'll sell the bullets quicker than you can make them. People will buy anything labeled SOCOM these days.

If the computer ballistics look good on all of the rounds, why not run a small batch of each and see which one shoots the best?

375 Ruger
 
I was wanting to know if you go with the 7 mm ( .284 ) Are you going to go with the lite 139 grain or the heavyer 175 grain or somthing in the middle, and what platform are you going to test from, please include rate of twist, I do alot of reloading but have never messed with creating somthing new, but now you got me thinking!!! This would take it to an all new level, and drive my wife compleatly nuts!!!

7mm/375 wildcat
 
I thank you rickrem for the interest and response. I'm going to use 1 of my trusty ruger #1s as I can put a 28" barrel on it and it'll be same oal as a conventional bolt rifle with 24" tube,barring that,I'll use a browning a-bolt action as I have in past used both of these platforms. I think 28" lilja,hart,or krieger barrel with 1-11 twist will work for 140s just fine from experience.

I've been thinking about this alot latly, this has the potencial to be one smoking mother hummer, I have a small family of Remington 700 ultra mags that I shoot long range with, not competition just for myself, I love all the math and probability of it all, primarly I use the 300 ultra mag on a 700 Sendero 11 platform, Remington came out with a three phase ammo package that gives you a pick of .308, 30-06 or 300 um. I thought this was a pretty good Idea to offer it commercialy, mostly for guys to buy one nice rifle and have the choice of rounds for differant applications, I know most of us hand load but for the guy who dos'nt this is a nice option, So I am thinking the Ruger .375 case is big enough to do the same like 7 mm-08 , .280 , 7 mm rem mag or what ever, I look to see other manufacturers start useing power level application on ammo that can be loaded real hot and also be available in a little cooler load, it gives them a great marketing edge!!! How fast of bullet are you shooting for? just a ruff estement will do,

If you neck it to 30 cal, you will have the honor of re-inventing the 30 Newton ninety-some years later.

Catfish 10-28-2007 10:33 PM

Just my thoughts, but I would think I would go with the 6.5 mm. There are alot of very good long range bullets available for it.
