    I finally got my own reloading setup and was wondering if I can load .30-40 Krag with Reloader 15 powder? I was reading about the powder and it said it is for use with .30 cal. but I cant find any data with people actually using reloader 15... Im new to this and need some help!!! Thanks!!! I cant wait to shoot my Win 1895!!!:D

    The only load Hornady 8th edition has listed for RL-15 is for their 220RN bullet.
    Starting load is 28.3gr RL-15 gives 1600fps
    Max listed is 33.8gr RL-15 gives 1900fps.

    Are you dead set on using RL-15? What other calibers (if any) are you going to load for in the future?
    For example, something like IMR 4350 has a lot of listed loads in various bullet weights for 30-40 Krag, but also works great in a lot of other calibers like 243, 7mm-08, 30-06, 7mag etc, etc

    Starting out, im gonna be reloading my Win 1895 (.30-40), Marlin .30-.30 and my 7.7 Jap Arisaka.. As for the RL-15, the powder came with the reloading set up and I have like 4 lbs of it..... Ive found the data for the .30-30 and the 7.7 using this powder, If its good for those, shouldnt it be good for the .30-40?

    I want to make just a light plinking load for the .30-40, Not a uber hunting load or anything.... I found these 100 Gr. round nose bullets that I was thinking of getting

    Speer Bullets 30 Caliber (308 Diameter) 100 Grain Plinker Round Nose Soft Point Box of 100 - MidwayUSA

    4lbs free???
    Well that seems like a good reason to me:D
    Give me a minute to dig up my Lyman reloading guide, may be able to help...

    Thats what I thought!! :D I really dont plan on shooting the .30-40 much, just to go plink every once in a while....

    What kind of bullet would be good to shoot outta both a .30-30 and a .30-40? would a 150 gr. flat point work? (My .30-30 is tube fed)

    Ill take any data you have. Thanks! I just bought a new reloading book with all 3 cals I listed. Ill see what it says....

    I've never loaded anything for the 30-40 Krag but the 150gr FP do work great out of a 30-30 and should work in the 30-40. My one bud used to have great results on whitetails with the Sierra Pro-Hunter Bullets 30 Caliber (308 Diameter) 150 Grain out of his 30-30.

    Hopefully someone with 30-40 experience will be along to help...

    Trez, that 1895 Winchester you're going to be shooting the .30-40 in has a box magazine as I recall. The concern for using round-nose or flat-tip ammo really only extends to tubular magazines where the point of the bullet rests against the primer of the round in front of it in the magazine. With a box style magazine you can use just about any bullet style you like as long as it feeds reliably. That said though, I would think round-nose bullets would probably be the way to go if you can find some that suit you.

    I looked in several of my old and new loading manuals and couldn't find anything in .30-40 Krag using RL-15. The loads I saw used my favorite powders like IMR-4895, IMR-4350 and IMR-4831.

    I have a friend telling me I should get some Alliant 2400. He says it should work in all three calibers. I made some Arisaka rounds last night using it. I havent shot them yet though.... Plus he said its inexpensive, around $60 for 5 lbs locally.

    Really the first two im gonna start to reload is the .30-40 and the .30-30. Im not going to shoot the .30-40 much, thats why I want a compatible bullet for both. Also he can cast his own so I would like some data for cast bullets if you have any..
    I have the dies for the Krag, but need the .30-30 and 7.7....

    Thanks again!

    Thanks Gate.... Looks like im gonna go with that data... It looks like I need to have that long bullet, if the bullet isnt long enough it will just eject out the top. It wouldnt even chamber empty shells, just spit them out.

    Would the starting load be good to test the 1895 with?

    Im looking for a heavy long RN FMJ... Any suggestions? It seems that that only make soft-points after about 150 gr., can I get a 220 gr. FMJ RN?

    I wanna try this:

    I do not have a 30-40 Krag but I do shoot reduced loads from my .303 British and 30-30 Winchester.

    [​IMG]

    Below is what I shoot for a reduced load and for fire-forming my .303 cases and the idea came from the Speer manual for the 30-40 Krag with their 100 grain plinkers.

    [​IMG]

    I would like to make a suggestion for just two bullets for both of your rifles, the .308 100 grain Speer Plinker and the Hornady .308 170 flat point made for the 30-30.

    You can use the 100 grain plinkers for both rifles for practice and fire-forming cases. And the 170 grain flat point for higher pressure hunting loads or full house practice.

    I loaded the 170 grain flat point in my 1943 03-A3 30-06 and used it for hunting eastern white tail deer in the woods. I did this for two reasons, the large and long military chamber on the 03-A3 was very hard on cartridge cases when loaded to higher pressures and would stretch and deform my 30-06 cases. The second reason was the Hornady bullets are "interlocked" and will not separate or loose their lead core.

    The 170 grain Hornady bullet was designed for 30-30 velocities and if you load it in your 30-40 Krag you will have a bullet when loaded over 2,400 fps that stops deer in their tracks. The 170 grain Hornady or any 30-30 bullet has a softer lead core than 180 grain .308 bullets designed for much higher pressure and velocities of 30 caliber rifles.

    Also you can keep the pressures down in your 30-40 with this bullet and save wear and tear on your rifle with lower pressure loadings.

    You will need two more powders, Trail Boss for your reduced loads and IMR-4895 which can be loaded to below minimum loading data and is very versatile when loading any rifle.

    As a side note I load RL-15 in my .303 British with very good accuracy results, BUT this accuracy accures at the higher pressures which can be hard on brass.

    Both your 30-30 and the 30-40 are loaded to chamber pressures below 40,000 cup and the RL-15 might not be as clean as burning as it it is at higher pressures.

    RL-15 is slower burning than IMR-4064 and faster burning the IMR-4350 and you should have no problem looking at a powder burn rate chart and extrapolating load data for RL-15 for your 30-40 loads.

    Of note is RL-15 powder is what is being used in our Army's long range sniper loads for the .308/7.62 NATO rounds.

    Alliant Powder - Reloder 15

    RL-15 is a double base powder and contains over 80% Nitrocellulose and less than 8% Nitroglycerin and the remaining percentages made up of powder additives. This means it has a higher energy rate per volume than single base powders like the IMR-type powders.

    Thanks for the info bigedp51!!.... Do you know if I can use the RL-15 in my 7.7 Jap Arisaka? Ive read that the 7.7 is a semi-rimmed version of the .303, and ive found data for similar calibers but not the 7.7...

    I found all the info I need (I think..) for loading .30-40 with RL-15, I emailed Alliant powder and they gave me this data:
    30-40 Krag

    150 gr Sierra
    RL 15 powder start 40 grs @ 2376 fps max 44 grs @ 2624 fps
    180 gr Speer
    RL 15 powder start 37 grs @ 2167 fps max 41 grs @ 2386 fps

    And Gate gave me this data: (Thanks!!;))
    The only load Hornady 8th edition has listed for RL-15 is for their 220RN bullet.
    Starting load is 28.3gr RL-15 gives 1600fps
    Max listed is 33.8gr RL-15 gives 1900fps.

    I finally made some rounds last night... I used Trail boss and their method for making reduced loads. I used 165 gr. hardcast lead flat nose bullet with a minimum load of 11.2 gr. (16 gr. is the max) Now its time to see how they shoot!!

    A big Thanks to Snakedriver for the brass!! :D
