Spent some time today testing a couple of loads I have worked up for my 375 Ruger Alaskan. As I normally do I thought I would share the results as I think this would be a great plains game load for any of you heading to Africa with a 375Ruger. For me the rifle and ammo is primarily going to be used for big pigs but also some very large thin skinned game (brumbies & scrub bulls). I have worked up loads using bullets at the lighter end of the scale for the .375 calibres, mostly because I want maximum expansion and energy transfer for the pig hunting, I feel that the heavier 300grn bullets will provide too much penetration for the task at hand. Bullets in the 250-270grn range will probably also be suitable as well but these loads with the 235grn bullets have worked out great so I will stick to them until the time comes I feel like spending some more time working up new loads for this rifle. Rifle used in the testing as mentioned above is my new to me, older model Ruger Alaskan in a full block alloy bedded Hogue stock with a Redfield 3-9X40 scope and obviously a 20" barrel, rifle weighs in at 9.46lbs.
I nearly use Woodleighs exclusively for all my hunting, and if not a Woodleigh another bonded soft point (DGX Bonded, Swift A-frame, Nosler Accubond) but in this instance I decided to give the Barnes TSX a go as a second option as they are also available in the 235grn weight.
I worked both loads up to be virtually identical.
Hornady brass
Federal LRM gold medal primers
And surprisingly 74.5 grains of Alliant RL15 put the 2 different projectiles at nearly identical velocities, both averaged very close to 2790fps.
Accuracy out of both loads was fantastic, both 3 shot groups at 75m coming in at 0.6 of an inch. There was nothing in it between the 2 different projectiles as far as accuracy goes.
I also did some penetration/expansion testing with the 2 different loads as I nearly always do with new loads I work up, more out of curiosity than anything as I am sure both projectiles are up to the task at hand.
Both projectiles fully penetrated X2 full 20L water drums each at 50 metres, the Barnes actually just managed to pierce the third drum and was sticking out of it, the Woodleigh also managed to put a decent dent and tiny pin hole in the third drum but was recovered in the bottom of the second drum. Penetration was virtually identical in this test.
235grn Barnes TSX
Muzzle Velocity 2790fps
Estimated Impact velocity 2638fps
Penetration 21 inches
Expansion 0.72 inches
Retained Weight 234.1 grains
Weight retention 99.7%
235grn Woodleigh PPSN
Muzzle Velocity 2790fps
Estimated Impact velocity 2638fps
Penetration 21 inches
Expansion 0.73 inches
Retained Weight 186.9 grains
Weight retention 79.6%
For me personally there is nothing in it between these 2 loads/projectiles, super happy with both of them. Obviously the Barnes would probably have the advantage over the Woodleigh on the game with heavier mass as it has better weight retention. The Woodleigh also has it's advantages, I suspect it will expand better than the Barnes at the longer ranges where velocity is starting to drop which is perfect for what I am doing with shooting large pigs around crops. I hope anyone that reads this gets something out of it, pics below of groupings, bullets etc.
