Get it running Sarg!

Thank you guys & yes a Express load is more likely what it uses, was shooting high until I got the loads up a bit .

I don't know how ever body else loads these, but I think it sucks, this cartridge could be a real giant killer if loaded up in a Ruger No1 or some thing as strong, but I have read the Martini's are strong ? (I now have 4 small one's & a spare 360 No5 barrel)

The Nitro loads just went "Click" bullet stuck in the barrel or "Click,,,,, Pow" only started to work with 40Gr IMR4198, a heap of filler & Mag primers !

It could be made worse by the Magtech case's having a little more volume I suppose, but the cases seem great & VERY economical compared to any other cases .

I have more to add on the cases & how the pressure works on them from BP to Nitro when I get time to .

Marrakai thank you for that load info, I think IMI 4198 is close to AR2207 & I used RL7 to, all went "Click" some time's untill I used the mag primers !

Tinker those slugs sound cool, dont get those from the local hardware store .

Do fillers not work well in bottle necked cases?

I've only used them in loading a .450 Nitro.

I use 21gr of dacron in my 450no2 cases (and a lot of Varget) for magnum bpe nitro for black loads.
works great.

What Tinker said.

For info, I have had no trouble with fillers in bottleneck cases. Just use your noggin and don't load wad material that could compress solid (like CoW!).
My favourite is saddle-felt, but dacron obviously works OK too. In my loads for the 20bore/.577 and the .577/.500 No.2, two 1/2-inch felt wads are needed. I work a fat wad through the neck onto the powder, and a neck-size wad on top of that under the projectile. Also did the two-wad trick with backer-rod on a friend's .577/.500 Fraser double. No dramas whatsoever.
