They being wyatts say you have to open up the ejection port but it is not needed. mine works fine no issues.The 4" box requires opening up both the action and the ejection port.

My bad I misread that.You really don't understand the comment since it has absolutely nothing to do with the bolt. It is milling out the bottom of the action to fit that extra long box.
I'm not 100% sure as of yet, I would assume 5-6 grains but I could be totally off.+P = By having a step in the lands, the bullet is farther down the bore before it hits peak pressure from the lands which effectively increases case capacity. How much will your case capacity increase?
I went with a 1:8:5 twist.The reason I ask is because we tried the 329's in the 375 Zayne. It's usable case capacity with the 329's was 125 grains.
I am rebarreling my 375 rum and will be adding a 28" barrel on it. I'm after the 300 grain bullets.
What twist did you go with?

Would you be kind enough to tell how extending the rail back 125 thou. is cobbling up a action? it will still shoot a short round just fine. this is long range shooting not a 6.5.Except you have to cobble up the bottom of your action to make that box fit and now it's only use is with that box.
It will feed 3.95 inch And i have had no problems with recoil banging the the bullet back into the case.i may be just lucky because the people that i know that shoot with the same box have problems with that length.I do use a little bit more neck tension than they do.So that could be why it works for me.What round and COAL do you shoot?
I have one I built on a model 70 super grade 300 rum. Only a hunting rifle so I am a bit limited with the 3.6 box. With a 25 inch lilja I am getting 2900 with R26 and a 300gr. Shoots well. In the Remington it should be better yet as you can put in a wyatt,s box and stretch it out. Your old 7 mag action will work fine. Just be sure to order the rum box and your standard bottom metal will work fine. A brake would be a good idea. I have a lot of heavy rifles so recoil doesn,t bother me and I would rather get kicked than blasted. In this rifle you may want to glass the box in solid to help out the stock. If you go with the long barrel 3100 with a 300 would not surprise me. Not for the weak of heart To add. Betram is making brass for it now and I like it.Does anyone here shoot one? I was originally thinking of doing a CheyTac build but I already have a 700 donor long action in the safe I could use I believe. Or am I wrong and the bolt face won't work? It's a 7mm mag action originally. But if the action will work, are any of you here using one? I'm thinking a 28-30" barrel shooting a 300 grain burly should get me way out there with a ton of energy, for much less cost than a cheytac build. Any help and or opinions are very welcome.
Yes it is, that's why I'm wondering if the action is strong enough for this cartridge
