	I broke down and tried 5 gr of unique today. Still get a pattern not a group and the bore is this original gun looks perfect. Giving up on 1:20 alloy. Going to something much softer. Let you know. I was pleased with a 90 gr bullet and Unique, showed zero signs of pressure.

	Update about shooting keyholes with Buffalo Arms BP loaded 25/20 SS. I got some 86 gr, 1/20, .257 (preloaded bullets weighed 92gr) lead SPG lubed bullets. In all loadings none of this weight bullet key holed. Nice round holes. Have not tried BP yet. But at 75 yards with 7.5 gr 4227--3", 8 gr 4227-4", and 8.5 gr 4227--1 3/4". So the keyholes must have been a function of the too long a bullet for the 1/15 ROT in this rifle. The diameter obturates the bore just fine, and the alloy seems to work fine. Now all that may change with BP.

	Late to this party - been putting up wood for the winter. My .25-21 Stevens 44 1/2 has 14 twist, stabilizes 257283 cast 1:20 just fine at anything from 1050 fps up to 1450 fps. Best powder so far has been AA#9; the old Chrony gives me markedly better S.D. than 4227. This is an original barrel, not perfect inside, but it shoots 2-3 m.o.a. on bench using fixed ammo. (Trigger is horrible - I'm sure groups will improve this winter, once I get to working that down.) Also have a .25-20 SS on a 44 1/2 action. Bore looks like the proverbial sewer pipe, but it shoots 86 grain jacketed under 2 m.o.a. off the bench. Grist for the mill.

	New to the forum. This has been read, digested, and received with some disappointment. I have a deluxe High Wall, got brass from Jamison (very good!) and am getting ready to experiment. Where does a guy (who is not lazy, devotes undivided attention to such projects) start? Is there a garden-variety recipe that seems to nearly always work in a High Wall (25-20 SS) nearly all the time, as a basis for further exploration for the particular gun? I refer here toward my previous experience with my Sharps guns (.45-70), and having Venturino and others give me a starting point with a load (bullet,primer,powder)suggestion that nearly always works (no keyholing, etc.), and go from there to refine to the rifle itself. I shoot BP in the .45-70 Sharps, but would gravitate toward smokeless with the .25-20 SS. Have experimented thoroughly with the Hornet, and found best results there with AA1680 and Lil Gun. Surely (okay, maybe not) there is a "go-to" load to begin with. Thanks.

	Well, Spitpatch, First you need a bullet mold that will work with your twist, a breech seater that will install the bullet at the right distance in the throat and then, start at 7.0 gr 4227 and work up to 8.5 in .5 gr increaments, using small pistol primers. My best load has been 6 - 6.5 WC820 and a 92 gr 257283. 25's are a little different animal. It takes a lot of work to shoot 240's. Bullet is smaller, but the work is magnified regarding obtaining accuracy. Frank

	Perfect! I'm on my way. (A long way, it seems to turn out.) Thanks.

	I am a great fan of all the Stevens .25 calibers, especially the 25-20 SS. I am having super results with the following combination in an original 44 1/2 action Model 45: 100 gr Barnett bullet, breech-seated; 30/1 lead/tin alloy; Winchester Small Pistol Primer; 6.5 gr. H108; original Winchester cartridge case. At the range yesterday, shot a couple of good sighter targets and then a 247 on the ASSRA 25 ring target at 200 yards. Vertical dispersion was about 3/4". Wind was from 9:00 and the 24 and 23 went out at 9:00 as a result of my misjudging the conditions. I think I'll keep this rifle! Leon

	WC820 and H108 are suppose to be the same powders so, That looks like a very promising powder charge. Frank

Wont use it because it hammers the case mouth down at six oclock. Good for about ten shots. I'm using a 111 grain Hoch tapered bullet. Made like a Pope bullet. Joe.

	I haven't had that problem in a few hundred shots with a 92 gr 257283 bullet and the same Jamison case. Maybe my neck is different, more taper, maybe? But, I think I'd put up with it, even so. Frank

	Okay, the load- 7 gr H108, no wad. 111 gr Pope style tapered bullet. Breech seated ahead of the case. Lands going about half way through the base band. Fed Small rifle match primers. Chamber reamer is Manson. Has integral tapered throat. Bertram cases Pictures are two views each. Straight on and side view. Four cases shown. The last case has been shot many many times with 4227 and is still in good condition. Joe.

	Made a mistake in the above post. The reamer is a match grade reamer by JGS. Joe.
