No. I have an RPR and since the factory mags are a bit short I got aftermarket mags to be able to load to 2.960 OAL.
I've used 168 and 175 NCC's and have loaded the 175's as far out to 2.940 as well as my 175 SMK's. But have never loaded to 2.80 OAL as I've always wanted more velocity than that OAL allows for any of the powders I've used. I feel sure you can get pretty good accuracy loading to 2.80 depending on the powder you're using . . . especially if you have a barrel tuner mounted. I get pretty decent accuracy with 168 and 175 Federal Premium Match cartridges that are loaded to that length. Custom loads with seating depths set to tune the cartridge to the barrel is far superior. Out of my factory barrel and my current Krieger barrel, the SMK's performed better than the NCC's I had, since I used the NCC's up I've stuck to SMK's and Berger's.
