All four of my rifles (300WSM, 270WSM, .30-06, and .243) have Remington 700 actions. You are correct, my experience is directly related to powder charge. When I worked up the loads years ago for each of these rifles I started with .5 off max SAAMI in batches of 3. If they were hard to chamber I'd back the load off .1 and so forth. The .30-06 and .243 were super easy and increased by .1 a couple of times to near SAAMI max powder charge. None of my rounds are over max. However, the WSM's took a little more work. Especially the 270WSM where I had a couple similar to your experience. Luckily I was able to get the rounds out. But, now that I have them dialed the bolts close firmly and cycle without issue. I prefer a snug fitting round, some don't so they shoulder bump.If you can reload over and over just by neck sizing and never have an issue closing your bolt then you’re doing something differently than I. With a 308Win, I can close the bolt with effort(I broke the handle off during a match once. Match over for me). With anything larger than a 308 Win it gets to the point that I can’t even do it.
That’s not to say that you aren’t telling the truth, but you either A) aren’t loading very hot, or B) aren’t doing it in a Remington 700(the only thing I’ve ever tried only neck sizing with). It’s entirely possible that your experience is different from mine, but it’s also an undeniable fact that my experience is applicable to a lot of shooters who reload.
I have cases with over 30 reloads on them. I did have to run them through a body die a couple times though.
I've also recently added annealing into my reloading process for what it's worth.
