Stupid rem 700 mag feeding question

[Its only light]

Hey guys I got a rem 700 long action that im wanting to bulid into a big 7mm. Im really leaning towards the 7mm rum right now. Ive got a couple others in mind but like the rum case. So here is my question:

I plan to put it in an aics chassis or a krg chassis. Im wondering if there are mags that work with this case when 180s are seated out to the lands? If so is there any modifications that need to be made to the action itself?

This may be a dumb question but its something I know very little about. What do I do?

Im also looking at the 7mm-300wm and 7mm lrm. I will go with one of these choices if the 7 RUM is a pain in the ass to get to feed or just plain wont work.

Either way HELP!!!!

THANKS!

I read an article on that a good while back and I am pretty sure people were running 338 lapua AI style mags. May have to modify feed lips and I know some of them had to remove the forward vertical ribs in AI mags because of shoulder location of the RUM. I dunno I will find article and post it for you.

This is talking about the 300 RUM but since thats the parent case of 7 RUM should work I would think.

Thanks man I will give that a look in a bit here. I want the rum that way if berger ever releases the 195's i will have plenty of power to drive those for the elr shooting im getting into.

I know there are plenty of other options which I haven't ruled out such as 7stw, 7mm-300wm, 7mm lrm. Im considering all of these which all have their pro's and cons in my book.

All of these will do what I want. My main objective here is to have a cartridge that will push 180s to 3000+ from a 26"-28" barrel and feed from an aics mag.

Abundance of brass and not having to buy a reamer are a plus for me. I have 2 kids that think they need clothes and 3 meals a day.

Could go old school with 7mm rem mag and have 180s throated at max oal of your mag system which ever u decide. That would prolly leave u some room to stuff powder. That would also relieve your mag concerns on the rum. All of them are good choices buddy. Best of luck brother.
