Just out of curiosity, how thick is your flower foam? I load my 32/20 with 4.8 gr. of Unique and 115 gr. bullet. I place the wade right on top of the powder. I cut the wad as thin as I can. About 1/16th in. or thinner. Have never had any type of problem with casings. Using star casings and Uberti 1885 low wall.boho wrote on Oct 24^th, 2015 at 12:43pm:

Thanks for your responses. I think from now on I will keep it off the powder. If the  cases continue to separate I want to re chamber. I have had too many come apart.
Every time I pull out the case I am looking to see if it's still all there.I haven't fired enough rounds with the wad at the top to really know if this will end the separations.
I am shooting a 32-20/.30 the bullet and barrel are .30 (.308) I want to keep it .30
The bullet is 189grns and 1.105"long it's a tapered Barnett and it shoots well. The barrel has a 10 twist. I would like to know what my options are for re-chambering.

Bob,
This is a case design it drew up when the wife's 32/20 was seperating cases. It's based on full length 357 Mag cases and a 32/40 type taper.

The throat would be my standard 30 cal neck and throat reamer of .120 long, .309 freebore with a 1 deg leade, forward of that.

I make my chambers in 3 steps, first the neck and throater goes in to the case length, then I do the tapered body, in this cae, .049 TPI. I then go in with a boring bar and cut the rim and headspace.

There is also a 30 Swartz (SP) out there, I believe it's based on the 357 Mag or Max but, I know nothing about it. I've just seen it in match equip. lists, a while back.

bnice - I have been loading floral wads on top of my Unique power for over ten years..45/70 with 11.5 grs. of unique and 405 gr. cast bullet. This is very mild load. Also load 32/20 with 4.8 Unique and 115 gr. cast bullet which is also very mild load. Never had an issue with either. Very thin floral wad like you mentioned is very fragile. Lot of shooters at our buffalo shoots use the floral wads and also cork wads. My thinking is the occasional ringing of the barrel is caused by hot max loads. Wonder how the shotgun slugs get by with the over powder compressed wad ?? Wonder how many shooters on this forum ever had or seen a barrel ringed by using floral wads? 

Did he scrub his barrel to make sure that was not a carbon ring. That is similar to what I shot for loads. I'm not promoting it but was shown this method by folks who have shot this way longer then me and have shot that was since.

When it comes to ringing a barrel, you can look at it this way: Basically the only way that you'll ever ring a barrel, is to put something inside the case. I know of no cases of chamber ringing from not using a wad or using a wad at the case mouth.

I'm one of the unfortunate ones that have rung a chamber! I did it back in about 1992, shooting my 30/40 Krag, HW. In my case, I was shooting BSed and it may have happened faster than a 32/40 or 32 Miller, because of the shouldered case. I say that because the ring happened about 1/10" back of the start of the shoulder, not at the bullet base.

It seemed to happen all at once, because it extracted fine on one shot and the next, it wouldn't extract. I knocked it out with a cleaning rod, thinking that it was just crude sticking it but, it would never extract again w/o using a cleaning rod.

I didn't use floral foam, I used Downy fabic softener foam sheets. It's a very open celled foam and is about 1/16" think and I cut them into 1/2" squares. Push them in, using the eraser end of a pencil.

I was using 18.0 gr of 296 and it happen within about 100 shots. I had chronographed the combination and got better ES and SD with it but, it cost me dearly. So, from then, until today, I never have and never will put ANYTHING inside the case.

In the end, it I was fortunate that it rang back of the shoulder, because about 2 months ago, I had a reamer made to make it into a 30/40 Imp and was again able to shoot it with great success.

BUT, I did learn my lesson.

not to worry, it will take more than  one guy with a RKS 11.5:1 NON-FAMILY BARREL to challenge your team of ringers. 


Care to fine tune my Pope to further even thing out?
