Been there, done that with the 195 in my 8" twist 7stw... I'm not going back until I have more case capacity... 7rum or greater... I'm wondering lately on the capabilities of the 183 Sierra; I'm also working with the 175 eld-x...
She'll do 3" @ 550 yards with rl33 and 195's, but the wheels fall off when it gets cold as rl33 only seems to stay stable for me in cold weather when you are in a very overbore cartridge with a ton of bullet weight. My 300rums with 225's work... The 300roy with a 225 does not. I haven't gotten a 7mm to work well enough for my taste. I couldn't get quite as much speed at decent pressures with faster powders in my 7stw so I gave up and gave my 195's away...
