I own all 3 and have run the 30 Nosler itself since 8 months before it was released at SHOT show. I don't mind recoil (hunting BIson this weekend with a 470NE and a 500 gr bullet. 111 grains of RL22 = RECOIL! LOL) but if I can get a little bit less and have nearly the same velocity, why not.
IME - using the same bullet and using a SAAMI length and chamber I have come up with this for Velocity - all use 210 ablr and the fastest/accurate powder
- 300 PRC = 3068 - 81.1 RTMBO
- RUM = 3061 - 92 gr RTMBO
- Nos = 3039 - 82.2 RTMBO
How did I take this information and why did it matter. I didn't need 3 30s so I
- Sold one 30 N
- Turned my 300 RUM into a 30 Nosler - Don't know why I did it that way, I guess I liked this one better
- Turned my PRC into a 7/300 PRC
Using standard loads, I can get nearly the same FPS using 10 less grains of powder. That said, if I start adding freebore and loading projectiles to XL mag capacities, the RUM catches up - but why...I have all the speed I am ever going to need with less powder.
This is pertinent to this thread because I think Hornady missed the boat with the 7 PRC and the shortened case. I think they should have taken the 300 PRC and necked it to 7mm - its reloadable, gets >3000 fps (fastest was 3120 with a 175 at the ragged edges of max) 3021 with 180 grain bergers and is plenty of wallop.
Furthermore, I didn't even have to use a nuclear charged case and Magic to get there LOL with some fantom powder combo that some witch doctor cooked up in the basement - components everywhere, and all I had to do was use the current 300 PRC redding die and change bushings - easy button!
