Since there seem to be more than a few folks interested in the 350 Remington Magnum on this site, I figured I would give another range report from yesterday when it stopped raining long enough to try out my test loads.

These were fired from my slightly modified Ruger M77MKII. The one I had to re-crown and re-bed.
I used a Leupold 2x7 VXII, with Warne quick detach rings. This rifle has back-up iron sights and two slings so it can be carried like a pack.

The temp was around 45 degrees F and the chronograph was about 20 feet ahead of my position. I had some odd readings which may have been due to the bright sun.
Groups are measured center to center with a caliper.

350 Remington Magnum Loads:

Hornady 200 grain Round Nose soft point.
51.0 grains RL-7
Fed 215M primer
Remington resized brass
2.800 COl with a light crimp
Velocity readings: 3,063fps (oil in bore) 3,001fps, 3,011 fps, 2,999 2,965
Group: 1.75 inch
Loads well in the Ruger action.

Speer 220 grain semi flat point.
62.0 grains RL-15
Fed 215M primer
Remington once fired brass.
COL 2.775 light crimp
Velocity readings: 2,847 fps 2,807 fps 2,801 fps plus two misreads
Group: 4 shots in a 0.25 in group with one flyer out to 1.1 inch.
**Note: I also tried this load with 63 grains of RL-15. It only went 35 fps faster. That load gave me a 0.75 inch group and lots more pressure signs.
Sometimes hangs up on feed ramp.


Sierra 225 grain boat-tail soft point
62.0 grains RL-15
Fed 215M primer
Remington resized brass
2.875 COl with a light crimp
Velocity readings: 2,829 fps- 2,819 fps- 2,821 fps- 2,814 and 2,823
Group: 4 shots in 0.80 in with one flyer giving a 1.1 inch group.
Showed the least amount of pressure signs. Also loaded well in this action.

Kodiak Bonded 225 grain soft point (Really weigh 229 grains.)
62.0 grains RL-15
Fed 215M primer
Remington resized brass
2.830 COl with a light crimp
Velocity readings: 2,835 fps- 2,799- 2,739- 2,741- 2,760
Group: 1.65 inch group
Does not cycle well in my rifle. I have tried other powder loads and COLs but these bullets do not deliver the best groups. In fact this was the best group they ever fired. They do have great terminal performance.

Nosler 225 grain Ballistic Tip (long bullet)
62.0 grains RL-15
Fed 215M primer
Remington resized brass
2.875 COl with a light crimp
Velocity readings: 2,751- 2,787- 2,750 Only fired three>
Group: Two shots touching, with one flyer out to 2.2 inch
Cycles well in my rifle. The flyer may have been because I closed my eyes for the first shot...Lots of pressure signs. Case neck and action not long enough.

Speer 250 grain flat based spitzer
57.4 grains RL-15
Fed 215M primer
Remington resized brass
2.875 COl with a light crimp
Velocity readings: 2,732, 2,713, 2,724, 2,564, 2,539
Group: 2.6 inches and about 5 inches lower than the 225 grain bullets.
Cycles well in my rifle. Weird readings may have been due to sun location.


Speer 250 grain flat based spitzer
55.0 grains H-4895
Fed 215M primer
Remington resized brass
2.880 COl with a light crimp
Velocity readings: 2,528- 2,552- 2,544- 2,532 fps
Group: 3.0 inches and about 5 inches lower than the 225 grain bullets.
Cycles well in my rifle. This load had a good tight velocity spread. So it must be my rifle twist. It would be nice to try this load in another rifle since it should be a tack driver.
