Thanks for the help. Bullet selection in Canada is limited. Speer and Barnes seem easier to get and maybe Woodleigh in 416 cal. Flat bases seem the way to go for maximum powder space in my set-up. Speer 350gr Spritzers, Barnes 300gr TSX and if I can get them 340gr Woodleigh Spritzers are my best...

Thank you, what is the Length of the Raptor bullets with the tip? It looks like you can put the tip on or off? I have a Weatherby Vanguard/Howa short action that limits cartridge length around 2.86”. Bullets around 1.250” seem to work best in my 2.1” WSM case. From this forum it seems Winchester...

That plastic tip adds a lot of length in a short action. I’ve thought of turning it off in a lathe? I think the standard all metal bullet design is better for large calibers. Really what am I going to gain with a BT in my little carbine?

350gr TTSX w/ 64gr W748 Choreographed only 2140fps compressed load. Think I’ll give up on the 350gr TTSX Barnes in the WSM and stick with shorter Lead bullets. The 300gr Barnes are only 1.256” long, may try in future.

Didn’t you have to open the bolt face on the Siam action for the WSM? I think the case head is 0.535”, just over the standard magnum 0.532”. Regular mausers are 0.473” head diameter, not familiar with Siam mauser dimensions.

I think the Taylor is a better choice after doing the 416WSM but don’t regret it. 458Win mag cases should be easy to get and form to Taylors and there is lots of published data.

With 350gn Speer hotcore 70gn of AR2206H gave 2417fps Also tried some 416WSM 400 gr Hornady RN with 57gr IMR3031 with some room for more, again no chrony but no pressure signs. Whacking 10” gong at 100yds no problem.

Fired some cartridges with Barnes 350gr TTSX, Winchester 748 powder today, 62, 63, 64gr slightly compressed. No time for Chrony info, just checked for pressure signs, all ok, shot great.

Barrel is just under 20”. With Speer 350 I could squeak a little more 4895 in the case but 3031 is maxed. Most on the site are using Accurate 2520 but I haven’t been able to get any. I’m happy w/the Speer bullets, just want to juice up the Barnes 350gr TTSX a little more. Think I can get some...

Will have to see how much 2520 I can fit in my WSM case when I try it. TTSX seems to shoot well with everything.

None yet, but I’ve maxed out those powders and am happy with the Speer loads. Have to see what else I can try for the 350gr TTSX. Wanna hit 2250fps. Availability limited here. I even tried H4350 as I have lots on hand but only got 1750fps slightly compressed load.

Thanks but the Thread is about the 350gr TTSX in 416. Haven’t been able to find Accurate 2520 yet but want to try it.

Range Trip Barnes 350gr TTSX, Cartridge 416WSM, IMR4895-56gr Compressed, 2113fps. Tried H4350 at 55gr Compressed no good, dirty unburnt powder, 1756fps.

Next Range Trip w/ chronograph best results, all Rem 9-1/2 mag primers: I) Speer 350gr SP, IMR 3031- 62gr, 2240fps, Cart. L. 2.860”. Ii) Speer 350gr SP, IMR 4895-65gr, 2229fps, OACL 2.860”. Iii) Barnes 350gr TTSX, IMR4895-56gr Compressed 2113fps, OACL 2.870”.

Emailed Barnes for required velocities to expand on the Barnes TTSX. Barnes rep,” An impact velocity of 1700 fps will get you about 1.7x expansion of the bullet’s original diameter. If 2x expansion is desired, which we suggest, then add approximately 100-200 fps.” Choreographed 350gr TTSX, 54gr...

Thanks, gonna try Hodgden or IMR 4895 next.

First Range Trip w/chronograph, not what I expected: I) Speer 350gr HC, 55gr IMR3031 1840fps. Ii) Hornady 400gr RN SP, 54gr IMR3031, 1750fps. Iii) Barnes 350gr TTSX, IMR 3031 54gr, 2000fps. Not sure if chrony is ok, should have checked it against a published load I guess? How do you calibrate...

I forgot to mention the other Cartridge combo on the right was the Speer 350gr HC, same weight big length difference in Bullets. Both loaded approximately to the same cartridge length. Borrowed a chronograph just gotta get to the range now to get more data.

I don’t think any bullet can really resist brush, I hit this deer in the neck while moving with a 0.416”-350gr Speer HC at 35yrds through brush aiming at his chest.

Haven’t tried crimping as grooves don’t line up but my latest loads with Barnes bullets are compressed so no bullet movement.

Seems complicated. Couldn’t you get a normal set of custom reloading dies from Redding or who ever? I just have 2 dies, one set of forming/primer punch and bullet seating/crimping. With the 40deg shoulder I would think you’d have to rely on fire forming for the last step with raw 300wsm brass...

IMR3031 is working for me now but still have no Chrony info to give. I wanna try 4895 next, local shop has some.

You gotta admit the older you get the more you like to carry a lighter shorter rifle. I don’t mind a 26” tube on my single shot but gone are the days when I’ll carry a full length bolt gun with one. I couldn’t imagine a 26” barrel w/suppressor, ear plugs are lighter.

I wanted a short handy gun so I got a Vanguard SA. Work with what you have. I think free-bore form the reamer helps with pressure spikes any how. It’s just ironic that the longest bullet shoots the best so far in a SA cartridge, WTF.

My action will not feed 350TTSX above 2.870” OAL or any other bullet. What are you shooting?

Notice only 1 band showing on my TTSX load, a lot of bullet inside case, but they shoot great.

The 350gr TTSX is compressed a little at 53gr IMR 3031, very compressed at 55gr with a stiffer bolt lift but the SPEER 350 and Hornady RN SN 400gr loads have some room for more powder at 55gr IMR3031 with no pressure signs. All with Rem 9-1/2 magnum primers. I like the powder, it seems like I...

350gr Barnes TTSX, 53gr IMR3031, 416WSM. Worked well no pressure signs. 2.870” total length.

55gr IMR 3031 was way too compressed, that was the flyer. Figured it was worth a try as I used 55gr for the Speer 350gr Hot Core.

Shot 416WSM w/Barnes 350gr TTSX, 53gr IMR3031today, slightly compressed load, 100m with no change to scope. Surprising how this caliber shots every bullet well. This was the best shooter though. I’ve read big bores aren’t picky on loads, wonder if this is common?

Been using IMR3031 in my 416WSM. Took from a 416Taylor load from a Handloader magazine article with magnum primers no pressure signs. Apparently this was the original powder used in the Taylor.

I’m just talkin about deer, I know nothing of Africa, listen to your PH. I’m gonna try 416 TTSX on moose, hopefully. This site is a great source for big bore ammo experience. Happy Huntin.

Only shot 1 animal (Deer) with my 416WSM, 350gr Speer bullets, 35 yds, worked fine but no expansion. I would stick with the Speers for small animals, don’t think the Barnes TTSX would expand at all, maybe pigs? Happy Huntin.

Too bad, makes loading big guns cheaper and great if you like odd calibers like me, Happy Huntin.

Thanks for the info, am gonna try these in my 416WSM wildcat for moose.

Tried reloading? Gives you lots of options.

Well got to shoot/bag a nice buck with my 416WSM but hit it in the neck at 35yds as it was moving through thick woods so I couldn’t see any performance from the 350gr Speer bullet, just a nice hole. Meat in the freezer. Anyone else have any luck?

I found article in Handloader Magazine for the 416Taylor where they used IMR3031 (which was available to me), compared volumes and adjusted accordingly for the WSM case. Speer 350gr Hotcores w/55gr and Hornady 400gr SN w/54gr of IMR3031. No velocity data available but absolutely no pressure...

I think WSM’s were 30 or 35deg shoulders, will lookup my drawing from PT&G.

My 416wsm had all the same angles and dimensions of 300wsm. So U have an AI wsm 40deg shoulder?

Can’t find a thread on your 375wsm, how’s it goin, any animals yet (bear season open)?

2.860” C.O.L with both HOR 400gr and Speer 350gr bullets in my Vanguard S.A. Rifle. I had some free bore in my reamer, Lead=0.167”, Throat=0.150”, 1deg 30min angle taper. I think I said to make it like a Weatherby Freebore chamber so I can seat bullets out to max length the magazine will handle...

AZDAVE, please give us an update on the 416WSM performance on game when you get a chance. No moose tags for this year so I will have to wait until deer season to try mine out.

TIG all the way with an SS filler rod as it was a shiny bolt already so I figured it had a high nickel content, still works good after 20yrs.

A gunsmith told me to machine and thread a bar of copper to fit snug inside the bolt leaving a few inches sticking out the back and hang a wet rag on it to draw excess heat away from the bolt while welding on the new handle. It worked well and now I have a jig for welding mauser bolts.

No over pressure signs on 350 Speer loads primers or cases. Horizontal impact no change from 400gr HOR RN bullets, just higher vertical as expected. Didn’t have to change scope. I’ll be able run the Fire formed cases through the final die no problem. It was only an advantage because I had the...

Shot 350gr Speer bullets with the 55gr IMR 3031 load, worked great, don’t think I’ll push it any more and will keep the 400gr HOR RN at 54gr IMR 3031. Need chronograph to get any more info. Tried fire forming some old factory 300wsm cartridges by shooting in 416 chamber. Had to clean in between...
