	I'm a Long time ASSRA member, but new to the forum - Any forum- so am not sure of what I'm doing. I recently built up a 28-30-120 on a C Sharps action. Got a bunch of cases from Rocky Mtn Ctg, and started some fire forming and load development. Well, using several different powders gave me some, umm, interesting results. Some of the cases developed dimples, some Really deformed the case mouth, some did both. Accuracy was non existent. The biggest culprits were with AA #9, 2400, and 4190. Granted, I started low and am working up, but the results seemed a bit extreme. Anyone out there with any experience with this cartridge willing to comment, or suggest anything?

	I had similar experience with that brass and #9. I gave up.

	I have had the same problem with 25-21 cases while breach seating . You did not state if you are breach seating and if you are using a wad in the case but if you are this helped me . I found less of a problem if I used 300MP and did not seat the wad as far down in the case , bullet seating depth adjustment farther out may help. I think the long straight cases are the problem.

	Search .28-30 Infro. 2015 listing. Seams 4227 or 4579 work best. J.W.

	I had a little bit of luck with this load in my Pope 28/30.

	Sorry. Yes, I do breech seat, and use a floral foam wad, either in the mouth, which results in hagnfires, or seated down on top of the powder charge, which gave me most of the case mouth disfigurement. I’m using an Accurate mould design I modified by having him taper the top two bands and eliminate the gas check shank. Drops at 120 gr in 1-20 alloy. I’m sure that 2.485" case with a charge taking only 1/4 of that is more trouble than it’s worth, but I’m fascinated by those long pencil-like cases. I'll look for some of that 300MP and add it to the collection.As for that very encouraging target, my 4227 load was with 13 gr behind the 120 gr Acc bullet.

	OK Here are some things to try. First dont put the wad down on the powder leave it between .050" and .100" off the powder. Second bell the case mouth slightly so you have a good seal at the case mouth. Lastly you don't mention primers but if you are using pistol primers start using rifle primers. 40 Rod

	I have shot an original Stevens 47 (44 action) for about 50 years. I shot with the Lyman 285221-120 grain bullet until I got a 140 grain Hoch mould. No going back. I use a 7 mm cork wad in the case mouth, pistol primers and 11 grains 4227 (4759 when it was around) because of the heavier bullet. Breech seat with a plugged case. No collapsed mouths with either original UMC brass or RMC. I prefer the original because it is easier to de-cap. No wad on or over powder.

	Thanks 40_Rod & Waterman, good input. I did flare the case mouths - do that with all new brass, these are RMC turned cases -, didn't seem to help much tho. I'm using CCI and Fed sr primers, and will try seating the wad just over the charge for my 2nd try. Will also be going to a heavier bullet whenever the mould gets here, and am looking for a 285221 in anything over 105 gr, heaver much preferred.

	I bought a brand new set of metric-sized hole punches for not much ($10?) at a swap meet. I use the 7 mm punch to make wads from a roll of thin cork-like material purchased from a chain-type fabric store. Made a lifetime supply of wads in a couple of hours. My 7 mm wads fit nicely in the case mouth. Don't put any wads down on the powder. Keep the cases upright until you load them, then insert carefully. The idea is to keep the powder back by the primer.

	I picked up a 25-21 the previous owner was loosing a case with every shot or two. I adjusted the seating depth to correct that issue and I have not lost a single case since. The rifle is shot breech seated using one case and no wads and the brass is Bertram and far from the best. The current case being used has well over 700 rounds shot while using it and is still without any issues. Powder being used is 300MP with Wolf SM Match primers and the barrel is a Douglas 10 twist with the bullet being the 120gr. Mos. JLouis

	After the 3rd firing, I still have some issues with these cases. I was able to blow out most of the dents and wrinkles in the upper third of the case by upping the charge. Still trying powders, mostly using 1680 and 4227, but 4227 gives hangfires, with or without a wad. Without is giving varying results on paper. Can't say accuracy is improving much, I think a heavier (longer) bullet will help there. Still haven't located any 300mp locally, so next stop is Powder Valley. Can't do much with adjusting seating depth with a plug, and am waiting on Weber's adjustable breech seating tool - along with a way overdue bullet mould. With floral foam, all I have to do is press the case mouth through a 8th" strip. Been doing that at CBA & ASSRA matches for years.

	Hopefully it will all very soon work out for you and I truly do wish you the best so you can start getting out and really enjoy shooting it. The 28's are remarkably accurate / extremely competitive and a real pleasure to shoot. JLouis

	To all you owners of original 28-30s, what is the bore and groove diameter of your barrel? I have a pretty early 44-1/2 52, #882, that has a 0.293" groove diameter with a 0.277" bore. The rifle was apparently a closet queen for most of its life and shows almost no use. I had not done any breech seating before so have been working with fixed loads. I had Accurate make a proper sized mould. Sometimes I get excellent 100 yd groups but am plagued with erratic ignition and get a lot of vertical stringing. Now that my CBA matches are done for the year I am going to get serious. I would get a tapered mould to try but am completely baffled on how to specify the band diameters. If someone would look at Accurate's 28-120-T design and tell me what diameters I should have I will order one.
