Home Forums Hunting & Shooting Ask The Gunwriters unusual chamberings

One of the (somewhat) local pawn shops has a Savage 110 rebarreled in some sort of proprietary Lazzeroni round, I *believe* 7.82 Patriot...no brass or dies available with the rifle, will probably have to be rebarreled again in order to make it something remotely useful.

Yep! I have some .303 ammo loaded with Cordite. In those the "powder" actually resembles spaghettini more than than spaghetti--and far more than "noodles."

One I messed with way back in the day!







Never had much luck with the "blue barnes bullets" (XLC) in regards to accuracy!


"Not long after the .338 Lapua was introduced, Ross Seyfried quickly wrote of the uncanny similarity of the new cartridge with his mentor’s .338-378 Keith-Thomson, albeit without the latter cartridge’s belt. It appears that Seyfried was closer to the truth than most imagine.

The .338-378 KT was based upon a shortened .378 Weatherby case necked down for .338″ projectiles. R.W. (Bob) Thomson reportedly wanted to use the full-length .378 Weatherby case, but Elmer Keith claimed responsibility for the idea of trimming the case. RCBS made the dies, Keith Francis made the reamers, and Bruce Hodgdon performed the earliest load development

The earliest rifles chambered for the new cartridge were built by Champlin-Haskins Firearms. Keith, Thomson, Bill Jordan, and George Gelman were among the first recipients. Bill Jordan stated that he was there when Thomson and Keith first proposed the idea. Thomson evidently had received his .338-378 KT Champlin-Haskins early enough for a late 1968 hunt. However, Jordan didn’t receive his ‘Keith-grade’ KT, until 1969."

Excellent cartridge, I had a ZKW465 reamed for the Spitfire. 40 gr BT at 3400 fps with AR2205 was no problem and no issues, used the original Brno barrel and it shot very well.

When you are serious, try finding the components for a Sako factory chambering of 7X33.

7x33 brass


Generally available from a few sources here.

Shrap, if you have a Sako peep sight laying around is there any chance you could measure the widest part of the dovetail, and the outside from side to side.

I can get the measurements when I get home from camping.

I don’t live in Western Australia, so brass is still unobtainium. I had to get it made from 30-30 brass and the bullets had to be hand made with some other stuff…

Rebels is in Canberra...try to avoid the West if you can

Back in the day I did have a 22-284 several years before the 6mm-284. without question the shortest barrel life of anything I have ever tried. To add to the disappointment velocity was never close to advertised. in this case ( literally) too much is just too much.
On the positive side it kept me from tinkering with the "Eargensplitzenloudenboomer" that is even a worse idea

i always wanted a 22x284 but never built one . but i do have 2 - 6mmx284`s they shoot 4,000 FPS with a 65 gr. Hornady V-Max bullet both are very accurate ,but i am sure both are barrel burners too.
