Help with decisions on custom Rem 700 action
I want to start work on a custom .500 whisper project. I will be slinging very heavy slugs at subsonic velocities. Due to the brass that I was going to use, I was going to use an action I already have which is a 700 short in .222. The bolt face is right, the price is right (free), etc BUT the action is not long enough, I need to accommodate a 3.0-3.1" cartridge which means I will have to heavily mod the 700 short. There is also indication that this gun might be too valuable to cut up and I might be better to sell it and buy what I really need.

The thought came to mind to see if I can just sell my complete .222 rifle and get a new 700 long with a .222 or .223 (same) bolt face? I have no need to buy new but not sure which direction to go. I will list a few specifics that I need. I should mention that I own a machine shop so some mods including the barrel chambering and threading will be done here.

1. Must be an action that I can get parts for, 700 seems perfect here
2. Must be able to mod the action for clip and make or buy removable mags
3. Common enough geometry that I can find a tactical stock to work.
4. CHEAP. Build is on a budget but I don't need junk.

If the 700 is indeed a smart direction to go, I would really like to find resources of places to shop for parts, possibly any resources for used actions or forums that specialize in the 700. I imagine if I could get a long action with mag feed and a bolt face close to what I need, I can probably work it from there.

I think you meant to say a 300 Whisper. The Remington short action should be fine though some modification would be necessary. It is possible to obtain longer magazine boxes from Wyatts. I'm not sure what sort of detachable magazine might be available which would take the 3.1 inch cartridge you specify. There is no such thing as a long Remington with a 223 boltface. GD

I was actually talking about a 500 whisper. Custom of course. Maybe the short is a better match for this since I need the .223 bolt face. I found that I can enlarge a bolt face a LOT easier than I can shrink it. Adding a ring in there is easy enough but I need to work with the extractor system in place.

I guess I might be asking if anyone currently makes a long action with the .223 bolt face?

What brass were you going to use for your 500cal cartidge?? The 500 whisper is a very real cartidge an based off the 460 weatherby case not a .222 and will not work in your action. Maybe the 338 whisper#2 will do as nothing larger will fit a .22 case. Your probable not going to find a smith to open up that action enought to help you. Any way the 500 or 501 whisper are major long cartidges compaired to any of the short whispers. You also will be turning your rifle into a single shot. Maybe time to sell and start with a custom single short action. Prices are not that high and some are remmy pattern action

The 222 case is only .378" at its largest diameter. So how are you getting it to .50"?

Exactly my question. Confusion reigns at this point. GD

That is not a reduced neck. That would be a rebated rim cartridge.

For custom 700 style actions there are two I lean towards.

Kelblys Atlas action.


Stillers SPF Tactical Actions

LOL. See where my head is today. Yes, rebated rim.... Thank you for the referrals.

I have a Lawton, and while it is a 700 style actions, it is far better than the one that being put out by the big green marketing machine.

Thing cycles like a Swiss watch and it's 100% made in the USA just for good measure.
