Norma 9.3x74R cases fully fire-formed to .40-90 Ballard and then "prettified" after a trip through my ss pin tumbler!

I bought a Ballard Pacific in 40-85 earlier this year and am having lots of fun with it.  I made some expander plugs and expanded the necks on 9.3x74r brass then fire formed them with a 400 gr lyman bullet sized to 0.409.  I replaced the sights with a vernier MVA midrange tang and it shoots exceptionally well with 67 gr of 1 1/2 Swiss with a 1/16 wad over the powder.  I drop tube but don't compress and seat the bullet all the way in the case (no grease groves sticking out).  I tried heavier charges ( up to 76 gr) and the fowling went crazy.  Also tried sizing the bullets down to the traditional 0.406 but they keyholed and leaded the barrel badly. So far i am sticking to this lighter load.  There is a BPCR shoot this weekend at our club so I am hoping to use it.  In practice I can knock all the targets down easily, lets hope I have some success in competition.

I do use a 3/8 Oring on the case and that seems to compinsate for the smaller rim very nicely and the extraction works without issue.  I didn't change the lenght of the cases as the fireformed seem perfect.  I only have 71 fireformed brass so may neee to by some more Norma brass from a buddy in Alberta.

Pacific in .40-85 have very slow twist rates, and you might also consider trying lighter bullets in the 335-350 gr. weight range. I'm using an RCBS CSA 335 that drops at 345 gr. with 30:1 mix. It's been much tighter groups than the Snover 410 gr. I tried previously.

Rex, are you located in Canada or the US?  I'm in Victoria, B.C. and I still have 100 rounds of once fired Norma 9.3x74R brass left for sale.  (I had 1,200 rounds shipped over from Germany, kept about 1/2 for my own use and have been selling off the balance to try to recover some of my original costs.)  I can ship them within Canada, but of course I can't ship them to the US thanks to current ITAR regulations regarding rifle components.

Rex,

Wow! What a beautiful rifle.  It has been very well cared for.

By the way, that cartridge looks monstrous long. I just went out and measure the case length on one of my 40-72 Win cartridges and it is 65mm long.

The .40-85 Bal. is just under 3" long.

My .40-85 Pacific:

Another very nice Pacific!  I think my next purchase needs to be a better set of sights for my .40-90 Pacific.  marliinguy ...  What do you consider the current best "bang for the buck" in a rear tang sight and a front globe set that would be suitable?  It would just be for casual target shooting at our local ranges, I won't be competing in any BPS matches.

The Lee Shaver Economy Soule is probably the best for your buck for casual shooting. The best is probably a MVA or Baldwin, or the higher grade Lee Shaver.
I am not a huge fan of globe sights for long range work myself. A .040-.050" wide blade works better, as when I hold off for wind the body of the globe often blocks out the target. A simple Skinner blade is much nicer, but a bit thick. He used to sell a .040" special order, but no longer does special order widths. I just file them down. The Skinner is also inexpensive at around $15 ea.

I was up at the range today with my friend Holger from Hamburg, Germany who is out here on a holiday trip, and so I forced him to fire-form a bunch more 9.3x74R brass in my .40-90 Pacific model.  (I didn't have to force him too hard though ...)

It's great to put an old single shot in somebody's hands and see how much fun they have!
