Lordy me no fellow. I use only my super highly modified NEFs. Of course some of them look a lot like Remington Model Seven's and Model 700s and such but that's only cuz they are so highly modified.
Actually ya have to look hard to find an NEF out there. I took my H&R .30-30 to the first shoot just to say I had one and when the folks started pulling out their rifles at Dan's that first afternoon I had to look long and hard to find anyone with an NEF. You'll see one from time to time but not often really.
This time I'll have a pair of Remington Model Seven Predators in .17 Fireball and .223 and a Remington 700 SPS Varmint in .22-250. I doubt I'll bother with any others, might but doubt it. Heck last year all I shot were the Predator .17 Fireball and the .22-250 anyway.
