Just picked up a Ruger #1 Tropical in .375 H&H for a steal on Gunbroker, with really nice wood as a bonus. I'm loading up the 250gr TTSX with 77gr of RL-15. I think this should be a very effective load out to 400 yds.

Please share with me your experience with the 250gr TTSX.

Thx
Michael

Great Bullets.

Great results on my PG safari up to eland.

I think I was using a bit less RL15 than you. I'd have to check my notes.

Mike, the 260gr Accubond is worth a try as well.

I think that you may find 400 yards a bit long for good expansion on that load.

I agree that the 260gr AB is worth a go at the longer range and the BC is good - memory tells me it was 0.473, but I'm sure it's on the net. I have used them for long range application of the 375 H&H.

Anecdotal only but I was contacted by a 250 TTSX fan who reported excellent expansion/penetration from that bullet on a 400 yard cow elk with a solid shoulder hit.

Cow collapsed instantly, and penetration was complete. He said the shoulder was so destroyed he did not bother with the boning chores.

since it is a single shot, have you considered throating the barrel to allow the bullet to sit at the base of the neck/shoulder junction? An extra 1/10th of an inch OAL can make a difference.

400 might be a push to keep that big ole' triple shock to expand, but I would think you'd have no problem out to 250....somehow those two words don't sound right 375 H/H--Long range...up close and personal sounds better !!!

I don't see any problem with the TTSX out to 400 yards. It will stay over 2100 fps and 1800 should still be good for expansion with the TTSX design.

Here is a 250 TTSX group with a 375 Ruger. The load of 84 grains R-17 and Rem 9.5Mag primer was very accurate in the Hawkeye 20" barrel. For the H&H I would recommend dropping 5 grains.


2800+ fps should be doable in the H&H since the 375Ruger load was not a max load. In any case the 250 gn. TTSX is a great bullet choice for 0-400 yard hunting.

I am shooting a max load of RL 15 behind a 250 gr TTSX. I am getting bit over 2800 FPS at the muzzle in my 22" barrel. This load will reliably expand at 400 yards on game.

Agreed. Cant imagine in this day and age that Barnes designed a 250 TTSX with such a narrow velocity window that expansion would be a problem at 400 yards.

Iv'e been loading and shooting 250 gr 375 Sierra's and Bitterroots in various 375 H&H's since the late 1980's and have yet to see one that would not deliver 2850-2950 with 4064 or RL15 from a 24" barrel.Ballisticaly the load is like a big 30/06-165 or 270-150 in all respects.

A no brainer from a 375 Ruger as well, I bet.


BTW my charges have been 77-78 gr RL15 for velocities from 2875 to 2940 fps from 24" Krieger and M70 barrels.

My experience with #1s is that they have not shot accurately enough to consider 400 yards shots. Hope yours turns out better.

In note to the above statement that Ruger #1 do not shoot accurately enough for 400 yard hunting, may I suggest that there is much that can be done to make the Ruger #1 shoot very well and shoot 1 inch or less groups at 100 yards. I did it with the Ruger 1-A in 7x57 mm. Mine shot many different bullets into small groups.
The first thing to clear up is the fore end fit. This will be the biggest accuracy fixer. It is like free floating a bolt action rifle.
By "Clear Up", I mean the barrel channel, and the face of the fore arm facing the action.
Sincerely,

I've owned several #1's over the past 35 years. Never owned one that wasn't accurate. My 7x57 1-A is a tack driver.

A local guy here used to specialize in tuning #1's. Free float the fore arm, and then drill and tap the hanger for a 1/4 x28 headless hexhead screw. He would gradually increase pressure on the barrel until it got to the 1 moa range.
I had a 1V in 6mm Remington that he got to shoot under an inch at 100 every day.

Google for no1 fixes. There are home fixes amd one sold by E Arthur Brown. Generally a screw up through the forend screw hole at am angle against the barrel. Anyway... thats for a new thread. The big bores seem consistently better in my limited experience with them.

If you want a stronger bullet than the AB shoot a North Fork. It probably has the widest useful impact velocity range of those mentioned. They expand relatively easily but BC is not as high as the boat tailed polyner tipped AB. I must say I don't think of a 375 H&H as a 400 yard rifle, but thats not the point I guess.

If a 30/06, 270, 280,338, 340,375AI or Weatherby
etc etc are 400 yard rifles, so is a 375H&H.

The 375 H&H is a high velocity cartridge with a trajectory identical to a 30/06,or a 338 Win Mag.

You are spot on with that analogy. Thanks

That would be a 'yes' on including a 375 H&H or 375Ruger to the 30-06 and 338 flat trajectory list.

A person only needs to add the 416 Rigby to the list of high velocity, long-range cartridges: for big game, flat trajectory, medium caliber.

Three-hundred-n-fifty grains in a sub-MOA, high-BC package streaking along at 2800-2850 fps would make a decent 400-yarder in my book. That includes the 416Weatherby, too.

Our 338 with 225TTSX and 416 with 350TTSX in Tanzania have almost identical trajectories, within an inch up and down or sideways out to 400 yards. It makes hunting and rifle choice kind of easy. Everything is the same, and either rifle is good to go, although the 416 gets the nod for buffalo.

Practically speaking, .416" is about the limit of easy-carry, 400-yard, flat-shooting hunting rifles. Yes, I would admit that a CZ in 416Rigby does add a pound to pound-and-a-half of weight over a Hawkeye Alaskan or African in 375Ruger. So 416 is probably the upper limit of this 270/30-06/338/375 comparison.
