30gnr and 338 JDJ #2 both 14" Alcorn, thought you shot the 338 JDJ on the 303 British Case? Wasn't aware you had the #2 as well...

Nice. I may still yet add a 358 JDJ...

Nice. I may still yet add a 358 JDJ... I remember it being snappy in the recoil department. But for pure power, it’s a great combination of the 375 and 338 JDJ in my thoughts.

I purchased a contender frame and stock/forearm many years ago. to that I mated a 15" 7-30 waters bull barrel from the T/C custom shop. I was caught up in the velocity craze and almost sent it to SSK to be improved, but after shooting it and looking in dis believe as I thought the scope went south after shooting 5 rounds and not seeing but one hole in the target. Turns out after cranking up the spotting scope it was a 5 shot elongated hole. Don't keep many targets but I kept that one. AS far as velocity, I found out things fell, mostly whitetail deer, and a few exotic's along the way, just as fast at 2350 fps as they would at 2700 fps. So it will, and has stayed just a plain "ol underrated 7-30 waters. crash87

The 7x30 Waters was an invention by one of my reloading heros, Ken Waters. He follows only Phil Sharpe in my book and not by much.
You can "Improve" it, but hard to make it better.
It's excellent in rifles and pistols.

Speaking of improved rounds, the Bullberry Improved velocities compared to standard Bullberry rounds (30-30 wildcats) are interesting.

Speaking of improved rounds, the Bullberry Improved velocities compared to standard Bullberry rounds (30-30 wildcats) are interesting. Yes, but on the 7-30 Waters the shoulder is already moved forward from it's parent, the 30-30 Win. Note that a lot of TC Barrel Builders offer Wildcats on the 30-30 Case. They EVERY ONE clammer and squawk that everybody "steals" their design. Only people that buy into this BS is those who've never heard of P.O. Ackley. They move the shoulder distance or angle enough from his designs to claim it for their own. It's absolutely ridiculous, but humans like to play the victim. The last two original case designs were the 8mm Mauser and the H&H Belted Magnums. Everything else is a copy. Taper, Shoulder Angle, Neck Length, etc can be altered. But, in the end, it's a interpretation copy.

Yes, what I was referring to is how in some cases with the 6.mm, 25, and 6.5mm Bullberry rounds the standard version posts better numbers than the Improved versions.

You're spot on Huey, nothing really new here, it's already been invented a long time ago. And I also agree about Ken Waters, he was way ahead of his time & everything he wrote was carefully thought out & tested before he wrote a single word, don't think I ever disagreed with anything the man said. I liked some of the improved calibers, not so much for the velocity increase but because the blown out case put less back thrust on the standing breech & there was less case stretching. The old 30/30 case had a fair amount of taper to it.

My 14" SSK 30-30 Ackley will shoot a 150 grn at 2400+ fps. That's pretty incredible even when compared to modern rounds.
JD Jones told he his 309 JDJ didn't offer much gain until you got to 165+ grn bullets. Another one that knew his business.
I do like the Improved Cartridges best for the Contender. I'm old school and grew up learning about back thrust, case head area and pressure.
I remember reading about shooting Improved Cartridges in Savage 99s with only the weight of the bolt holding the cartridge in place.
Sadly, there are a lot of gimmicks and dishonest salesmen out there. The affordable chronograph has really been an eye opener for many who are still willing to learn.

Alcorn, thought you shot the 338 JDJ on the 303 British Case? Wasn't aware you had the #2 as well... The .338 JDJ No.2 is a SUPERB cartridge! It really is. I've had a 22" Carbine Barrel in 338 JDJ #2 for close to 30 years. 2600+ fps is easy with a 200 grn bullet.

Some time in the 90's I had JD build me a 338 #2 in a 14" barrel, it was scary accurate. I was shooting 200 gr Nosler BT's I think & after a few weeks of getting use to it I believe I could have hit a Lizard at 100 yds it was so accurate. Milk jugs, pop bottles, etc, it didn't matter, the only thing that gave me any grief was scope power. If I could see it, I could hit it with that gun, once I learned where to hold. JD made amazing barrels.
