Does anyone have a visual comparison of a 38-55 rotor along side any other known cartridge rotor? How different are they from, say, a 303?

Thanks,
Jeff

I think I have one at home. Doing MIL duty until 5/19. Can check when I get home if no one else has them.

Thanks Mike

I remember seeing a pic with a bunch of rotors lined up and labeled. I thought it was in tal35's parts pics. http://photobucket.com/savparts but can't see it. I think it is in the stickys or linled through them.

Thanks Dell, Todd!
Here it is, any guesses which one might be the 38-55? ...first two on the left maybe?

Some where I have seen a pic, where they were laid out and labeled as to caliber.

The one on the far right appears to be for a .284. That's all I can tell from that pic. Wish I could give more information.

Here is a pic I found with labels

You will have to save the picture and then blow it up.

OR click on the picture and just depress the "ctrl" key and tap the + sign. To return to default size, tap the - sign.

Thanks Todd!!

Just pulled out my box of rotors and I don't have a 38-55 either.

Need a volunteer to pull one and show us what they look like I guess?

Mike I thought for sure there was one in your box of parts.

I believe the 38-55 and the 375 are the same. second on the left.

I've often thought there's no reason the cartridges wouldn't both feed interchangeably, but what about the pesky receiver length differences between the pre and post 900,000 guns? Would a 375 rotor fit in a pre 900K rifle, or a 38-55 rotor fit in a post 900,000 rifle?

Roy you are absolutely correct on the length difference.

I'm recovering from a brutal case of the flu so I don't have the energy to do a lot of digging on this but it may be possible to adapt a rotor across the 2 versions.

I never tried it, but you should be able to adapt it into an older model. The actual receiver is the same. The thin, solid rotor shaft support on the older models was removed and a removable sheet metal stamping was added to give a little more room. If you shorten the new model rotor, it would probably work. I would try a common rotor like a .303 first. It is amazing what will crossover and work sometimes.

Thanks Calhoun, you just taught me something about computers !!

Yup, the idea of modifying a post-mil 375 rotor to fit a 5-digit receiver, makes much less sense than modifying a 303 rotor work with the 38-55

303 will probably work for a 38-55 if you CAREFULLY hog out the front of it to allow for the straight case. Cut out the material from where the shoulder starts and it should work. Work slow, measure twice and work slow again.

I would at least try the .38-55s in another rotor. You would be surprised how well the "wrong" rotors work sometimes. You may only get one or two work through the magazine, but who cares? One up and only one or two down is plenty for hunting unless you expect to have to mow down a whole herd of deranged deer doing a banzai charge on your position.

I hate it when that happens!

When I was a kid we were small game hunting the first day in PA. A couple of us were moving through standing corn and a buck passed me going full speed in the row next to the one I was in. If it had been in my row it would have knocked me down. Just a memory jogged by a post. We had it made when hunting as kids.
