As stated before I use a Ruger M77MKII Stainless All Weather to launch the 350 Remington Short Mag. (The original Short Mag as far as commercial success is concerned)
The advantage of that particular rifle is that they used a faster rifling twist.
Thus I am able to stabilize heavier bullets.
Plus I think the magazine and chamber are a touch longer. So I can load a little longer COL.
Out of hundreds of experimental loads.
My favorite loads so far, from my modified M77MKII Sourdough Survivor:
200gr Barnes Triple Shock: 60 grains H4895:Fed215M: 2.786 col
=2,800 fps and a 0.50 inch group.
225Gr Sierra SPBT: 62.0gr RL-15 : Fed215M:2.875 in COL
=2,820 fps and a 0.80 in group
225gr Nosler Accubond: 53.0 gr benchmark: CCI-250: 2.875 col
= 2,590 fps and a 0.70 inch group
250gr Hornady Round Nose: 56.0gr H4895: Fed 215M: 2.785 col
= 2,540 fps and a 0.75 inch group
280gr Swift A-frame: 56.0 grain RL-15: CCI-200: 2.800 col
= 2,410 fps and a 0.80 inch group
