30-40 Krag ammunition is expensive. And for reloaders, brass has been increasingly difficult to find. An easy solution is to convert 303 British brass to 30-40. Dimensionally they're nearly identical except that they're about 0.100" or 2.5mm shorter. This isn't typically an issue as the 30-40 case has a very long neck. Some attention is needed to the bullet choice and the seating depth to mimic 30-40 Krag.

Nothing like going to the range and hearing boomers shouting about their ruger revolvers lmao

3:28 Finally, you are using the right sizing wax on an imperial cartridge.

Now I need a Krag so I never have to trim my 303 again, just go straight to converting it. Life hack.

@shiftymcgee4183 Месяц назад

Nice that one seems to be the most straight forward conversion out of all the variations you've done so far?

@kmorris180 Месяц назад

With this video, you have helped me and earned my subscription. I got blessed with a 30-40 Krag a couple of months ago and was trying to figure out what to do about brass. I only have about 30 or so. I can get my hands on 303 Brit. Thank you for posting this.

@RUSTYCHEVYTRUCK Месяц назад

For some reason I always thought .30-40 was a shorter cartridge, maybe just bc I compete it to .30-06 which is very long

@JerryRussell-cv6ng Месяц назад

I never thought that, I have convert 30'06, 270, 260 brass to 8x57 mm. Thanks for the video!!!

@ditzydoo4378 Месяц назад

Excellent video, easy to follow well done. Now I have a new source for my 1898 Krag CMP with its 03 Springfield re-barrel to a 22-inch carbine.

@rickt10 Месяц назад

Every year, around hunting season, Brownells used to get 30-40 Krag in stock for a short period of time. Don't know if they still do. I got enough to re-load years ago.

@STMwoodturning Месяц назад

I have done something similar years ago to get my type 99 7.7 Japanese running. I Converted .270 Winchester brass by just running it through the 7.7 sizing die. Also had to trim it down a little and inside ream The neck. Worked great

@tynado1173 Месяц назад

I do the same. I haven’t needed to ream the necks using 270

@michaelmacek9433 Месяц назад

I have converted a lot of GI .30'06 brass to different calibers over the years. I use a permanent marker to color the heads so that I can tell at a glance what caliber the converted brass is. This would not work for anyone not familiar with my coding system but it works great for me. The same works for me with 11m/m French Gras, Dutch Beaumont, 8m/m French Lebel, and others converted from .348 winchester brass

Great video

@TheRedneckPreppy Месяц назад

I'm surprised that the Handloaders Manual of Cartridge Conversions even bothers listing .405 Winchester as another possible brass source given the easiness and ubiquity of .303 British brass.

@andrewsteele7663 Месяц назад

Great tutorial, just wondering once you have fire formed the new cases. Do you see any length increase in the converted 303 cases?

@elazarsinger4187 Месяц назад

Thanks for making this video! I've been rebuilding a krag, and ammo has been one of my biggest concerns. Well that and the fact that I'm building an 1896 krag carbine, and my goodness, finding a rear sight seems to be near impossible!

@rakumprojects Месяц назад

The carbine sights are out there, but they're expensive. If I were rebuilding a carbine I'd just get a rifle sight.

@elazarsinger4187 Месяц назад

@@rakumprojects my understanding was that rifle sights would require adapting? I couldn't get a clear description of what kind tho. I don't have the ability to do any metalworking, but the stock is new made so I wouldn't feel bad about altering it

@rakumprojects Месяц назад

@@elazarsinger4187 All US Krag rear sight models are interchangable, but they may need different screws and need to fit the handguard you have. The only difference between rifle and carbine sights are the carbine sights have a C stamp and are calibrated slightly differently.

@elazarsinger4187 Месяц назад

@@rakumprojects thanks! I'll give that a try!

@mckutzy Месяц назад

After an annealing of the case, Couldn't you make up a fire forming load instead of the resizing process...Kinda like if one didn't have those die sets???

@rakumprojects Месяц назад

The sizing die is necessary since the 303 case can't fit within the 30-40 chamber without the shoulder being pushed back first.

@Bidimus1 Месяц назад

Nice, and like the remarking of the brass. Could the sizing die also be used as the case holder ?

@rakumprojects Месяц назад

It would likely get stuck in the die when using the punches

@Bidimus1 Месяц назад

@@rakumprojectsThanks.

@samiam619 Месяц назад

@@Bidimus1I use the case holder whenever I have to pull some bullets. A lot easier than those three jaws held together by an O ring that comes with the inertial hammer! It’s a Franklin Arsenal product.

@craigthemonke794 Месяц назад

I wonder if a krag can be rechambered into 303 british or is the brit cartridge too high pressure?

@rakumprojects Месяц назад

303 British is probably slightly too hot for the Krag action. You'd also need to open the bore to .311", however some Krags have oversized bores.

@michaelsaine Месяц назад

i dont have a 30-40, but cought my attention couse i have a 303 rifle. this looks intresting and even though i dont have 30-40, i wanna try it

@guaporeturns9472 Месяц назад

When in doubt you could just oust the shoulder down just a smidge more to make sure it chamber properly , don’t you think? It headspaces on the rim , right? If you push the shoulder back a bit over it will fire form to the correct size won’t it?

@ZacharyBurgard Месяц назад

I am lucky my grandfathers buddy has a bunch of it from when they were still making it in a decent amount and I have a huge amount of brass from him

303 brit is rare too dont waste it for that bs

@geodkyt Месяц назад

.303 is in current production, such as the PPU he was using. I've also bought US commercial .303, without having to look THAT hard. Advantage of using modern brass is the primer pockets are already made up for easily obtainable Boxer primers, instead of the British milspec Berdan primers. It's certainly far more available than .30-40 Krag, and well under half the cost as .30-40 Krag.
