350 Remington Magnum (who needs it?)

[Float Pilot]

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

That's a nice all around rifle you got there, Float Pilot, and I'm sure it puts the smack on most everything.
The Rem carbines were good, but I really like a bit more barrel length like you have.

Thanks Smitty...
It has turned out to be a good all-around carry rifle. And properly loaded 358 bullets will do the job..

As I previously posted here and on a few other forums..
This M77MKII All Weather has a few extras besides my odd-ball paint scheme.

1. Re-crown
2. feed ramp improved
3. Ejector modified to allow longer COL
4. Magazine feed lips modified.
5. Front sight with perforated hood installed.
6. Rear Sight (back-up peep) from NEGC stored in stock compartment.
7. Second sling added to left side.
8. Storage compartment installed into buttstock
9. Cleaning gear stored in buttstock.
10. Action and barrel channel glass bedded.
11. Scope storage tube made for back-pack frame.

I am currently modifying a bubba'ed 1903-A3 to see if I can make one in 35 Whelen or 338-06....

The big plus is that the 350 RM fits in a short action. It also fires a 35 caliber bullet, which can be more effective than a 30, but doesn't show up in energy figures. Just another reason to take energy figures with a grain of salt.
