Fixed in the 32/40

Cold not much shooting going on this is the time of the year I play around with loads for the new season.

I am thinking about shooting my CPA 32/40 offhand rifle with fixed this 2011.   2010 I shot two Hudson matches breech seating and one with it's rimfire barrel.  The CF Hudson's fired breech were real hard matches. Spring cold and very windy, summer very hot and windy too.  I was disappointed with my scores. Made a lot of errors and fatigue was an issue. Either one to get 100 record shots shot another 50 on the sighter target. 

Meanwhile the rimfire Hudson I did well. Have been shooting a monthly club match with my other CPA in 38/55 that does not allow breech seating and done some of my best work.  If I just put a cartridge in the rifle and all of my effort on breaking the shot scores may be higher.

Except for my gallery fixed load only way I have ever shot that CPA is breech.  I am willing to give up Half a Minute to fixed. 38/55 difference in breech vs fixed is about 1/2 MOA.

Anybody have advice on bullets & molds etc let me know.  Powder Brass Primers Loading fixed etc I am pretty up to speed on it's the bullet I an concerned with.

Boats,
Some things that you have to deal with on a standard 32/40 chamber are,

The neck has a little more that .007 taper and the throat has more than a 21 deg angle leade. neither are very good for fixed ammo accuracy.

I would suggest a Hudson style bullet (319273), size the neck only enough to hold one base band and jam the bullet into the throat. 

Best bet would be to throat the chamber with a .322 ball seat about .10-.12 long and about a 1 deg leade.

You might try a machined case and put a step in it to hold the base band of a tapered bullet. That way you don't have that tapered neck to contend with and can use a good bullet.

Frank appreceate the tip.   

Will look up that mold.  On the throat I don't want to alter the existing leade since this is just an experiment may well go back to Breech seating

Machined case is an idea, I have 20 RMC turned cases that could be opened up to accept a bullet and give a stop. Might try a few as well as regular drawn brass cases

Boats,

     The most deadly accurate fixed .32-40 ammo I ever shot was some that came with that ill-starred Ruger #1 with custom Douglas barrel that I once owned.  It was a 200 gr +/- Welch bullet in front of 14.6 gr 4227, lit by a Federal Bench Rest primer, all in a W-W case.  I probably should load some more of those, but I sold the mould with the rifle.  Cry

Froggy I am either going to get a plain old new made Lyman 165 gr 2 cavity 32/40 mold and give it a try or just shoot my 38/55 fixed in your June match. Just to test the theory out. 

May work may not. The Lyman with lube sizer dies top punch and all about 100 bucks so not a lot invested.  I have shot bullets like it fixed in .30 US Kraigs with 2 moa results before, the heavy barrel better sighted CPA will probably do better than that. Thats my guess anyway

boats I have shot the Lyman 319247 165gr bullet and the Saeco #632 32-40 165gr tapered bullet, the Saeco wins hands down, if your CPA is throated for breech seating the Saeco bullet seats in the case mouth on its base band and fits into the taper throat like a glove, have never fired it at 200yds but the 100yd groups were in the 1" to 1 1/2" with 13.9grs of H4227 from my CPA 32-40 bench rifle, almost the equal of my breech seat loads. Almost forgot to state that I shoot the Saeco's as cast, pan lubed.

Good luck and let us know how it works out for you,
MIKE-T

Both good tips Mike will look that Saeco up. My fixed pratice Smokeless bullet for the 38/55 is a Saeco. It shoots nearly as good as breech with a Nose Pour Hoch bullet. I would rather pan lube than lube size, it's faster

Difference in the two is less than 1/2 MOA Col will also have a look at the 8mm's

Boats, 

Before you go buying new moulds, contact me via PM or e-mail.  I think next time you are passing through I can fix you up with a mould or two to try so you can figure out what will work before you commit.  I have the original old 319247 and a number of others... I think you will want to go with one of the 175-185 grain bullets though, rather than the little 165.  JMHO, YMMV, hence the need to try them!  Cool
