350gr ttsx in 416

Here is my velocity ladder. Unfortunately with my magneto speed attached all shots were over the target. Which having it attached always makes my rifles shoot 6 inches or more high. I just forgot to put up larger target. Speeds seem pretty good. Gonna try and seat them deeper cause all the tips were flattening during recoil. Think ill load up some of the charges in the lower 2500's and allow me to seat a little deeper. No pressure signs today so that was good.

75.5 and 77 grains is where I would go next and try shooting some groups. Good luck!

What I was thinking also! Gonna try longer drop tube to hopefully seat bullets a little deeper. Here is the 350 speer load I been using. Very accurate load hopefully I can get the barnes to similar spot.

Unfortunately i wont be able to load any ammo for awhile, might be moving back up to alaska here soon (pending my job interview here in fairbanks on tuesday). So I'll have to try either before i move or more likely after

Good luck on your interview man.

Hope it goes well for you.
 
Tried out 75.5 and 77.0 grains of RL15 today. I would be pretty happy with 75.5 gr load, but 77.0 seemed to scatter. I may try out some more seating test with 75.5 gr load. If I dont find some more 350 speers it will have to be my back up load this season.

I think in my rem mag I'm going to start at 80gr and work up to 84gr, before i mess with seating depth
 
Going by what is shown from your ladder test I would do a OCW from 76.5gr's to 78gr's in 3 tenth increments.

May try that also. I made up an 8" drop tube to help the powder settle for more seating depth. But that is a long bullet and all loads are quite compreseed in my case. Seems this bullet would work better in the larger case 416's. Or if I had a little more magazine length would be nice. At 3.360" is about my safe max length for reliable feeding, and thats with it battering the tips flat on the 2nd and third rounds in the mag box.
 
If you plan on using the gun for elk/moose/bear et. al. in America, (or you're just practicing,) that's fine, but why not use the heaviest-hitting, highest SD bullets there are for DG hunting in Africa? The 400 grainers are just perfect (SD .330) but the 450s (SD .375!!!!!!!!!!x10e23) is Divine. Per Kevin Roberston, they hit HARD! My .416 shoots 1-hole groups w/ 400 gr DG bullets, so why wouldn't i use these on the occasional PG trophy? (A .375 w/ 350 grainers performs better than a .416.)
 
I think double-tap makes factory ammo in .416 T, 350 gr. but i wouldn't use 'em on DG as the 400s can be handloaded to 2,450+ and the 450 Woodleighs to 2,350+. Much better.

Unfortunately I dont even have elk lol. Just little old whitetail deer, maybe a stray pig ever once in awhile haha. I have played with the 400 DGX some and really wanna try some 410 woodleigh. I just have not been able to find any lately. Ive just become very fond of the African calibers, so now I have the 416 and two 9.3x62's

For whitetail deer, I think you will find that the heavier .416s are kind of a waste. They punch through deer from any angle like they are punching through a sheet of paper. They will definitely expand if the deer are close (especially the Woodleigh, it has become one of my favorite bullets), but the 410 is is probably limited to 2,100-2,200fps in a .416 Taylor (depending on your barrel length) without running the ragged edge of pressure and getting short brass life. By my calculations, they are below the threshold for reliable expansion at 100 yards (1,900fps is probably the lowest for reliable expansion in my experience) and you will likely not get full expansion at 50 yards because there isn't much resistance in a deer. If you don't plan on shooting farther than 100 yards, it will definitely kill, but if your looking for a bullet to perform on animals that size, The 340 grain Woodleigh Weldcore PP is fantastic. They open up reliably, hold together and can be pushed out of your Taylor at 2,600 fps with less recoil! Still massive overkill for deer, but if you want to you use your Taylor on deer, that's the Woodleigh bullet I would recommend.

Thanks! I looked at those, but have not tried them yet. I have shot 150 rounds of the 350 grain speer mag tips. In my taylor improved I reached 2700 fps with no pressure, but settled on 2610 fps for accuracy. I originally chose this bullet because I figured it was probably the softest 416 bullet available, and would work on deer pretty decent. Cant find them now, so i may look at finding the 340 PP as a replacement.
 
Number 5 out of about 30 or so applicants so far. One more quarter until the final interviews and a decision on the number of apprentices they take in this year

I had pretty similar results with a 22 inch Douglas barrel using 350 grain Barnes bullet, earlier model TSX? 2550 fps. One shot, one brown bear at 215 yards, behind right shoulder out left shoulder, rolled down hill, squared 9 ft 9 inches. Commercial Mauser action, sat in Cosmoline for 30 years, waiting to be something, three round magazine was two more than I needed.

Between the 350gr TTSX and 400gr TSX there probably isn’t much practical difference. I used a 400 gr TSX on my one and only Buffalo. One shot, through the shoulder, quartering towards us. It shed 3 of 4 petals, but took out the near shoulder and penetrated well. This resulted in a very uneventful recovery.

For buffalo and maybe hippo, I’d favor the 400 at 2400 fps, just because it’s a tried and true recipe. I wouldn’t hesitate an instant to use the 350 TTSX though.

Digital Hack Recovery managed to recover all of my lost funds. It was a relief beyond words, and I couldn’t believe it actually happened. I had almost given up hope, but thanks to Digital Hack Recovery, I got my money back and regained some sense of control.I am incredibly grateful to Digital Hack Recovery
