Well, the first two or three loads have been loaded and shot. all the loads from thirty years ago rotted the brass so I had to procure more brass, fire form and get down to it, the first loads of 90grns of swiss 1-1/2 made too much pressure and was pushing the primers back in the firing pin hole. cut back to 85grn.s of single F swiss. shot two groups of five each, 100 yds, 7.5 inches on one and 7.125 on the other. load is, 85 grn.s 1-F swiss .063 veg wad. .125 felt grease cookie, and another .063 wad, w/the bullet just barely crunching the powder, the bullet is seated about 3/16 deep in to the case, I can pull any of the bullets easily with my fingers. the bullets are 350 grn swaged straight side patched w/ .002 tracing paper, making a finished bullet of .4025, my krieger barrel has a .405 bore, 7degree leade w/ no free bore.  Is there anything in my loads that just sticks out that is just blatenly wrong that doesn't work? my wads may be too big, I'm making them 7/16's because 3/8's wads are loose in the neck. should I make a custom wadcutter to cut .410 wads or is this a non issue? I am using a 3/8's rolling paper "wad" to keep the powder out of the primer hole, CCI BR rifle primers. I am not at this time duplexing and would rather not if I can get away with it, I wipe between shots(one wet, two dry). the sights are the cheap set of lyman front and lee shaver economy soule rear. I would be very grateful if someone with experince with this caliber would point me in the right direction. thanx fellers,  Dave.

The barrel is a 32" 1-16 RHTwist. I have a Hoch nose pour that I have cast about 8 or 9 hundred bullets thru and have maybe got thirty good bullets out of, however when it does make a good bullet it weighs 372 grns. it throws a slug that is .395, which makes the same dia. as the swaged bullets.  I think that my twist might be a bit slow for your 450's. the only reason I am using the light bullets is, I have 400 of them and they are consistant on the weight. my cast bullets will vary 4to5 grns b to b.  Dave.

Dave,

Is this application for hunting only?  The reason I ask is the bullet patched to 0.4025 is rattling around inside a 0.405 bore.  My PP loads are target oriented, so I try to get the patched bullet to bore diameter; for example if I had a 0.405 bore, I would shoot a 0.4049-0.4055 diameter bullet. Is your barrel for a 405 Win rifle?

What alloy are you casting those 370 gr bullets?  I cast 20:1 in my 40-50BN and 40-70SS, but harder is better in my 40-82 and my 45-70.

For wads, you will need about 0.002-0.004 over groove diameter. 7/16" wads are a bit too much.

With Fg Swiss BP, my favorite primer is Rem 2 1/2.  I put a copy paper wad in the primer pocket.

Keep on hav'n fun!

Well, went to the range today and shot two back to back three inch groups at 1 hundred yards. the paper is coming off great, leaving a lot of confetti 3to 4 feet out in front of the muzzle. I have reduced the powder charge to 75 grains and it seems to act better. I had to seat the bullets down in the case a good bit more than I wanted to(half or so),but I didn't know what to use as a filler. I didn't want to use a whole stack of wads, or three or four grease cookies to get my .125 seating depth back. I think that the group size will shrink a lot more with the bullets seated out where they were.  I am going to try some remington primers as most seem to get the best results with them. the paper I used this time was some old patches I cut 30 yrs ago from 25% medium bond typing paper, do they even make typing paper any more? anyway, someone chime in with what is being used nowadays.  Dave.   P.S. does anyone know a fellow named Dick Schrieber in Bloomington Mn. and how I could get in touch with him if possible?    Dave.

Mike, that is the one! had some corresponance with him 30 yrs ago about my 40-90, area code has been changed from the number I have. Thank you very much.  I have to figure out a way to clean my cases. what will work in my big lyman vibrator?  ceramic? those little stainless thingies? white sand? I don't want the same thing to happen to this batch of cases that happened to the last bunch, and I was sure they were clean. Dave.

OAAT, yes, I don't at this time have a decapper to take with me to the range, but they do go in to a soapy water coffee can as soon as they come out of the gun, and are cleaned as soon as I get home from the range(20 min. from home).   Dave.

With the primer flow you may be getting inconsistent ignition, which will effect the shot. Was having a similar problem (inconsistent ignition) with my 38-56BN and found a piece of 'crud' stuck up under my firing pin (High Wall). The shot would go off, but the variance on the target was significant. Many folks think that if a primer goes off it is always the same. High power shooters know this is not true and it is same with our rifles. Bushing your firing pin may solve your problem and also make the rifle safer to shoot (a pierced primer is always a bad thing).
