what about the rimmed cartridge in a bolt action?

[444ttd]

i've been sitting here thinking about my 1898 spr armory action (one of three) and what 375 caliber i should use? i was going to go with the 375 krag for its "speed", but i'm not into "speed". the 375-303 is like looking at a mirror. what other rimmed cartridge do i have? then it hits me, the 38-55. its one thats on my bucket list and i don't care if it is a single shot or not. the CUP is 30,000 while the 30-40 krag is 40,000 or so.

i can use bp and smokeless powder, but i'll "probably" stick with smokeless. maybe put on 24 - 26" barrel and a leopold 2-7x and a huber trigger.....mmmmmm.....250-300gr+/- boolits.......i can taste deer steaks already. and i can take it out target shooting.

now this ain't next year, i have three other rifles to build(7x57, 22 hornet and 257 roberts). but what say you?

The 38-55 SAAMI chamber drawing does not permit the chamber mouth (neck) to be any larger than .393 while the groove dia is limited to .379.

A .379 bullet will not chamber in WW brass. WW brass is .010 thick. You have to use the thinner Starline brass or turn the case necks of WW brass. The best solution is to open the neck of the chamber. Then it is no longer a standard chamber.

i'm going to go with the 38-55 McPherson(2.125" case length starline brass).

Does the smaller rim on the 375 cause any problems with the Krag bolt face.

Does the smaller rim on the 375 cause any problems with the Krag bolt face.

i've checked on my 30-40 krag and found although the smaller case(30-30) the extraction is "doable". the smaller rim concerns me. it probably needs a "bigger" extractor. i am going to do a 22 hornet in 1898 spr armory next year. on another forum, a guy has the exact same thing. when the time comes for me to build the hornet, he will be "my best friend" and my gunsmith just luvs the 1898 spr armory, he has seven of them.

As I was reading the original post, the .38-55 or .375 Win immediately came to mind. I've always been intrigued by that action and by rimmed cases - where are you finding bolts, bottom metal etc?

i was going to use the 375 win but the CUP is too much, 50,000 i think.

There is a cartridge that may interest you. Called the 37 rimmed and is nothing more than the 303 British case necked up to .375 with no other changes. There is a very tiny vestige of shoulder left but it does show up on the print when I googled it. Don't know who may have the prints for the cartridge or dies but again maybe google to the rescue. Just type in "the 37 rimmed cartridge" at least that's what I did. British #1MKIII,any of the #4's, P14's, and the Krag actions should be able to be converted to the 37 rimmed.
Twist could be 1x12 or 1x14. One of the members on the nitroexpress forum's mentioned it to me. Frank

thanks...one of my friends told me to go with 7mm krag. i like 7mm(7x30 waters, 7-08, 7x57), the deer hates it. maybe i could AI the 7mm, just to keep the 30-40 krag separate. i'm also looking at 375/45-70 and the 375/444 marlin. i'm pretty sure that 375/444 marlin is a no go because of the psi/cup/cip. i have a couple of years to decide on it.

[ulav8r]

375/55 would be a good choice. .375 barrel with a 38-55 McPherson(2.125" case length starline brass) chamber. Use .376 boolits with 38/55 data. Mark it as a 38/55 and no one else will have problems with it.

[Jedman]

Remember that any wildcat round that you use will be hand loaded my you or the owner of the gun so pressure worries are not a problem. You can’t buy factory loaded ammo for it so a wildcat based on a magnum case or other hi pressure cartridge means nothing.

How about the 45/70?

[Texas by God]

A .35 Krag would be neat with near unlimited choice of bullets and work through the magazine as a bonus.

[country gent]

You could maintain the krag bolt face with the 40-70 SS formed from 30-40 Krag brass. Another 38 caliber option with a bigger rim would be the 38-56 Bottle neck on the 45-7- case. Just somerhing to consider

[444ttd]

smithnframe,
i own a handi rifle in the 45-70, its my loaner gun. i have owned a handi three times and they have all been 45-70. one i sold long ago. two, i gave it to friend's boy. three is a loaner. handis' were cheap, but since their discontinued, they're expensive as heck. i've used the 45-70 to kill deer, but it got quickly boring. now i have a tc encore in 23" MGM barrels in 444 marlin and 500 linebaugh.

texas,
i was going to get the 35 krag, but i can't find reloading dies or ch4d tells me 2 years till i get them. ch4d is supposed to have a 35-303 British but it ain't the krag. i have a Winchester m94(1972) in 35/30-30 that JES Reboring made. it is sweeeeeeeeeeeeeeeet. i put on a williams fp aperture sight to get rid of original rear sight and my groups shrunk.....alot!!! i should get JES to do 35 krag and what other reloading dies do i use? (hmmmmmmm.......i'll have to get back to you on that.) that 7mm krag, that my friend told me about, got my head spinnin. i have used the 7mm's on deer and they are one shot kills. like i said before, the AI version will most likely be it. just to separate the 30 cal from the 284 cal.


does somebody have a time machine they don't want? i would go back when i was 12yo and tell myself that different calibers are not needed. be happy with 30-30, 22 lr and the 20 ga.


yes, i am a rifle-holic and i don't need no help!!!!!!!!

You could maintain the krag bolt face with the 40-70 SS formed from 30-40 Krag brass. Another 38 caliber option with a bigger rim would be the 38-56 Bottle neck on the 45-7- case. Just somerhing to consider

30-40 krag with 165gr rd, 9.3 krag(.366"), 9.3x57 fired, 9.3x57 with 275gr wfn gc



i tried forming a 35 krag with my limited dies(35/30-30) and i found that the sizer die is ok, but it causes the case OD to become smaller. next i tried the seater die and it was a no go. then i remembered what someone else posted, so i immediately lubed up another 30-40 fired case and i put it thru the 9.3x57 sizer die. i took me 3 or 4 times but in the end i had a 9.3 krag decapped. i then compared a 9.3x57 and a 9.3 krag. the krag is a little longer than the x57 and the neck is longer than the x57.

so i got a 9.3x57R........maybe. i tried to google it and i found that they do have a 9.3x57R, but its case is tapered. the 9.3 krag has a bottleneck. its also a black powder round. well, whatever it is, its got me thinking!!!!!!

Does the smaller rim on the 375 cause any problems with the Krag bolt face.

A goodly number of Krags were converted to fire .22-3000 R2 Lovell back in the day. Single shot only, obviously. Rim is only .378" diam. Takes a considerable addition to the extractor hook, but it's doable.

[RU shooter]

What about the ole 35 Winchester as an option

[444ttd]

from another post

I believe It operates in the realm of 38-40,000. It will definitely work with the magazine (same rim and case diameter) but may need to be loaded slightly short to function flawlessly.

Well, since you don't want a duplicate .30-40, I voted for the .35 Krag. IIRC it will more or less duplicate the .35 WCF.

Robert

i like the 35 win but i think it should be a 9.3, 6.5, 7.....krag. i'm sorta interested in the 9.3(36) krag.
