I have a quick question about ammunition/reloading.

I only have two 90 round midcaps for my preferred primary (Echo1 Sof 1). I have never played at a milsim event yet and I was wondering how feasible this ammo count would be.

I do have a m4 platform with around 6 midcaps i can use instead, and I expect many others will also be running m4's so interchangeability of mags would also be a benefit. That said I would really like to use my sof1 out there so I am just wondering if i would have the ability to reload/rearm between deaths and such.

Thanks for any and all advice.

As some others have said, two is going to be difficult.  I would say you should have at least 4, I usually run 6 (120rds).  I also agree that interchangability isn't really that common unless you're in some crazy firefight and absolutely need some and happen to have a dude in your squad that carries like 10 mags on them (these crazy people do exist).  I would say try to pick up at least two more before the event, otherwise you're going to spend the whole day wielding a speedloader, reloading mags, instead of playing, and that's no fun.
