Just noticed tonite that Hodgdon has posted some .405 Winchester data on their website.

http://www.hodgdon.com/data/rifle/405win.php

They've played with the Woodleigh 400gr bullets too. Apparently they got the same max load that I did with both Varget and H4895 but they have the benefit of a pressure fixture. Under 45,000cup, so I'm probably safe in my Ruger #1 and not about to blow my fool self to perdition. Plus they're using a short OAL in deference to the 1895 lever gun which gives me a bit more wiggle room with mine loaded to 3.30".

Thanks for the site as there's other info on it that is important for reference and comparison to other data.

Rick,

Thanks for the heads up. I can get 3.29' OAL with 350 Speers, which have been swaged and/or turned down to .4105". I think I can get the 400 Woodleighs out a bit further than 3.17" too, it depends greatly on the ogive of the bullet. When I worked with the Woodleighs I did not try and see how far out I could go. I really like the 350 gr bullet better. I think it provides better overall ballistics.

Hodgdon's load data is a bit faster than what I have been able to achieve with 4895, but that is probably within the spectrum of rifle to rifle variation. The pressures they are recording are in line with what I have calculated with my load devlopment. 4895, 4064, and Varget are too slow for optimum performance, in my opinion. My rifle is a M1895 Winchester.

NOTICE- That Hodgdon has no 400 gr loads over 2000fps and stays below 45000PSI. So how do you get 2200 fps out of this cartridge in a M1895 Browning lever gun without 67KPSI of pressure, as our site liar SCOTTS claims? You'd have to be a fool to believe anything a clown like that has to say! In my experience Hodgdon's max loads are usually on the hot side.
Now I do believe that with a Long throat version of the 405 and a 26 inch barrel that 2100 fps is attainable with the right powder combination and in a rifle that can handle the extra pressure such as a Ruger #1 and/or a TC ENCORE rifle. When I get a chance, I will publish MY loads and PRESSURES required to SAFELY HIT this threshold in a 405. Win.-Rob

Hey-Scott can you read or are the meds your on affecting your vision? Lying piece of shit! Has HCI brainwashed you into a coma?

Looks like a potent round.

2400 fps for a 300 grainer WOW.

I wonder what 49,000 psi would give for 400 grain velocities. The 375 win is loaded to that pressure and doesn't blow up rifles. I think the pressures are being kept low in respect with older rifles.

I also wonder why you guys think that 67000 psi with blow a rifle up. My 300WSM uses 63000 for a working pressure. If you cant blow a brass case with that pressure how is a rifle supposed to explode. I am NOT recommending using this load. I was just surprised to see some of the reactions from some respected posters here about high pressures.

I think it was Roy Weatherby that tested his first rifles at 200000 psi and couldn't get one to blow. He did ruin a couple though. Brass cases will give out well before the rifle will. As long you work the loads up slowly you will lose cases well before you blow yourself up.

This is JMHO so take or leave it.

ScottS and 470nitro are currently on my ignore user list so I probably won't respond to them.
