7lb 375H&H is an interesting choice.

I now understand this design better after working on my own safety design. The initial force to pull the cocking piece off the sear is high and needs a large pressure pad on the safety lever or else it is uncomfortable. I have also improved the ramp on the cocking piece to help the safety pin...

Time will tell where the US economy will end up. To be clear ABC is Australian Broadcasting Corporation. https://www.abc.net.au/news/2025-05-28/us-dollar-dive-pressures-australian-superannuation-pool/105345312

Much safer for a westener to visit South Africa that the South African President visiting the White House!

I think Metalsmith is on the money. If you look at the attached diagram the bolt body including the handle and locking lugs is one piece so there can not be any wiggle there. In the photo you have the safety engaged and you have slightly lifted the bolt handle, which is what you are describing...

Bob @ Kudu?

Just to set you straight. This is not from American Broadcasting Company USA - This article was from the Australia Broadcasting Corporation which is funded by the Australian Government and is some what independent.

Guess your not that interested in how the China US tariff changes are perceived outside the US but I will share it anyway. https://www.abc.net.au/news/2025-05-13/trump-china-tariffs-capitulation-markets-respond/105285374

338/348Ackley Improved reamers are in the post from PT&G. Sprinter ChromeMoly barrel with 1in10 twist No3 contour@25" has been received. Siamese Mauser action bolt handle has been modified to clear the Burris 3-9X40 scope on Leupold one piece low scope mounts. Walnut blank is about to be ordered...

No- the Siamese Mauser cartridge was a rimmed cartridge and the rim diameter was 0.555, so if anything the bolt face is a little too open. It is feeding and ejecting perfectly after adding the 0.8mm plate to the right hand side of the magazine box.

Another interesting perspective on the last week. https://www.abc.net.au/news/2025-04-11/trump-china-and-the-possibility-of-tariff-trade-war/105155856

I doubt you are that interested in a perspective from down under, but I found this article interesting. https://www.abc.net.au/news/2025-04-07/tariffs-trump-world-will-move-on/105143574

Feedback from my cousin is that he does not like the left hand side activation. He would prefer that it fuctioned the same as early Brno safeties. Where forward and right, orientated across the bolt is safe. Fully back and orientated in line with the bolt is Fire. By only mirroring the lever I...

Totally agree with your sentiment. I have learnt far more from my mistakes than any other experiences. Thirty years ago I also overloaded my 280AI, but you learn and move on. The worst outcome would be to stop your learning and buy factory ammo.

Norma brass is the best quality brass you can buy. If everything is measuring in spec then I just wonder if something had fallen into the case before loading that took it from 82% to 100+%. Trouble is that you will never know

I doubt that 0.3gn is the root cause of the issue. There is something else going on? How did you measure the powder? Were all the cases trimmed to length? Did you check clearance to the lands?

If you are going to build on a Siamese Mauser action, then the 416WSM is the best choice due to the cartridge length of 2.950" and the Taylor @ 3.340. If you are going down the 416/348W cartridge then you need to open the bolt face unless it has previously been modified for 45/70. For a virgin...

My cousin has a 358NM built on a Zastava M70 action. He was not happy with the factory safety as it does not lock the bolt handle. I took my first proto safety that was assembled into a firing pin assy using K98 parts that I bought from SARCO to try on his Zastava action. The firing pin assembly...

Screws in from below.

Its always easier to remove metal, so beefy is a good place to start. I have another 29 to play with and get perfect. I had been using Aliexpress stainless dowels, and they were not hard and started to show signs of ware. When activating the safety the fealing was"dowy". I bought some proper...

Polished it up a bit.

After exploring a few options on how to machine the safety lever, the version shown below was cut out of 6mm sheet with a laser cutter. The hole positions were laser etched with a X, which I later drilled in the mill. The 3mm dowel pin was then pressed into the lever. I then used the dowel pin...

With 350gn Speer hotcore 70gn of AR2206H gave 2417fps With 400gn Hornady 67gn of AR2206H gave 2251fps Neither load had pressure signs.

Hodgdon's H4895 is manufactured in Australia and is sold here as AR2206H. It is specified as being temperature stabilised. I easily get 2400fps with 350Speer hotcores with a 21" barrel.

Love a Martini rifle, I have 4 working and 1 in progress. The largest is in 45/100 and is built on a Greener shotgun action. Unfortunately it was only when the engraving was being done that it became clear that the Greener actions are quite soft. So it is restricted to black powder only. The...

After building plate alloy boats & gyrocopters - this is a cheaper hobby.

The 333 Jeffery with 300gn projectiles had a great reputation to be able to penetrate. My 338 Sprinter barrel arrived last week. And my 416/348 Ackley Improved reamer is back at PTG being reground to 338/348 AI. Another Siamese Mauser project. On an action that had previously been modified for...

Ok, now I fully understand your issue. I have a Timney safety on my 93 Mauser. After my experience using it, that is why I am looking at making a better alternative. The 3 position Winchester type is the best design, but the only company that makes a version for the Siamese Mauser will not...

Yes the Chapman is a 2 position safety. I does lock the bolt, but then you cannot disassemble the bolt. I am not at all familiar with the Springfield action, I have never handled one, so I am struggling to fully understand all your good work from the photo. If it works, then you have to be happy.

I annealed the M98 bolt shroud by putting it in our electric pizza oven @ 400C for 30minutes and then pulled it out and heated the safety area with the propane torch until it was cherry red. Then back in the pizza oven @ 400C and took an hour to slowly turn the oven down and get it to a point I...

The frustration is that down here we have Bertram Brass, Woodleigh Projectiles and ADI propellant, so if there could be a reliable agent in the US we have all the components needed. Bruce was looking at loading some "boutique" cartridges but it was not stacking up financially.

Yes, my mistake was that I did not get the B709 first.

If you get your spiral tubes from an Athletics company in SA, there is no risk of any problems with the shipment. Always best to support a local supplier where possible.

SARCO in the US were still shipping parts to Australia last year - I hope that has not changed. Then you need to be careful with Australian Border Force as some parts need an import permit. Magazine components including W springs, M17 bolt, K98 triger all got pull up, but I was able to get the...

Given the $, it is more likely to get the Aussie big 3, Banteng, Buffalo & Scrub Bull.

On the safety front, to do a proof of concept I had an associate print one of my designed safety levers in plastic. For some reason unknown, the hole for the locking pin was missed, so I will have to drill it. I need to anneal the bolt shroud and then modify it to accept the lever. Trials...

Blue is the input data and green is the output from the calculations. If people want to share load and velocity data for 350gn loads then I can update the table. One hell of a political chill comming up from the US as well!

Don't know if you are familiar with the song, "Mad dogs & Englishment out in the midday sun". It was one of those days here, it was 35C (95F) when I arrived at the range and maxed out today at 39C (102), so I guess you can say my loads are calibrated for the heat. I started with continuing the...

I totally agree, I have passed up a few animals simply because they were on the skyline. Especially when using large calibre rifles.

This has just come up - unprovoked Kangaroo attack. https://www.abc.net.au/news/2025-01-30/kangaroo-attacks-man-walking-to-his-car-at-the-gemfields-qld/104875142

Seeing the rifle is buggered and untrustworthy, I will give you $10 to get it out of your sight.

That is the ruling here, 270W is the legal minimum for Sambar.

For me, I prefer to build my rifles on ex-military actions, as they have been designed to operate flawlessly in atrocious environments. The operating lever / bolt handle, must be promonent to aid quick and reliable operation. Safety on a bolt action must lock the bolt handle and cocking piece...

I think it needs a bit of lubrication, if maintained they operate like silk.

The P14 and M17 also achieve this requirement. I find the P14 & M17 safety easier to access than a bolt shroud mounted 3 position safety.

Another member here, sent me a 416Rigby case that had gone through the Lee Factory Crimp die for reference. I then made up a new collar to replicate the result. This 416WSM collar needed 1.5mm of projection out of the collar to replicate the result. The little pip you can see in this photo is...

I don't think there is anything wrong with the chrono. Granted I have been using AR2206H, but with similar charge weights I am getting similar velocities. I only went up to 60gr which averaged 2087fps with 400gr Hornady. No pressure signs. I have now progressed up to 70gr which is just starting...

That puts a totally different perspective to the discussion, including the safety.

I would set up for both and then decide once I know the terrain to be hunted. Scope for open country and the red dot for thick cover.
