	Hey guys I just picked up two real nice German Aydt rifle in the standard 8.1546 cartridge. I want to shoot at our monthly matches and I am looking for suggestions on a good powder charge. I am using a 165 gr banded bullet with a resized 30-30 case. A couple old time shooters suggested using IMR 4227 with approximately 10-12 grains of powder with a large pistol primer. I was wondering if anyone has had any experience using Unique or any other powder and if so what powder charge(s)? regards

	You might try 10-10.5 grains of 2400 or H108 or the usual 32-40 load of 14-14.5 grains of 4227.

	Slug the bores of each. Maybe do a chamber cast of each, including the throat and a bit of the barrel. That will tell you an awful lot that you really need to know. I have two, chambers & barrels are very different. Might as well be two different calibers. Both do a lot better with breech-seated bullets than with stop-rings. Please show us photos of both.

The first one is a very nice engraved Aydt made in St. Wendel Gr in 1925 and the other one is a first model reformed with internal extractors, plain CC receiver, made in 1927. Both have like new bores. I did slug the bore on the first one, its (.317/.318) diameter and also did a chamber cast. The case looks like its about .870 long. Since there is no real receiver edge to grab or brick block/receiver cutout to use with a standard BS like a Webber, how do you propose using a breech seat a standard cast bullet???

	There have been several posts about 8.15x46 loads. I have several rifles in that caliber, bores tend to vary in size, most are .317 to .318, but have one that slugs .312. I Taylor the brass length so that the stop ring touches the throat. Cast with 25 to 1 alloy the NEI mold throws a 172 grain bullet. I use 14gr IMR 4227, Remington 9 1/2 large rifle primer. At one time, I used large pistol primers, but didn’t like the primer set back on firing. I have been shooting this caliber for 35 years and like 4227 the best, probably because it meters uniformly and is easy to find, I am lazy. Thanks Mike

	I breech-seat both with 2 different plugged cases. My 1888 vintage Martini requires the rims of all .30-30 type cases to be turned down to 8.15 specs. My Aydt uses made-over .30-30 cases with no rim turning.

	The Aydt has a swinging block. How far out from the breech does it pick up the rim of the case on closing? Enough to seat a bullet with a plugged case?

Enough to seat a bullet with a plugged case? Works on mine. Also, with breech-seated bullets, you are not limited to a 46mm case length. The case can come right up to the base of the bullet, or nearly so. The fired cases look strange, but so what?

	I have three: a Buechel Meister, a Nimrod and a no name hunting rifle. All work well with a stop ring bullet and 13.6 grn of 4227. I ran out of 4227 some years ago and loaded up a batch with 10grn of Blue Dot. Only used at distance up to 100 yds, but very good groups. I have both re-formed 30-30 cases and a lot of original RWS factory brass. They weigh the same and have the same internal volume. No difference at all in performance. While the three bores are the same dia, there is a significant variation in the chambers. The two schuetzen rifles have very tight chambers but I normally reload the hunting rifle ammo by simply recapping, filling and thumb seating the bullet. These will not fit the schuetzen rifles.

	Stop ring 160, 1/50 alloy, 13.8 I4227, no resizing necessary. Charming rifle to shoot.

	Accuate 300-MP The Doc Hudson Ideal 375192 was the most accurate out to 300yds

	I have an Anschutz Schuetzen Rifle with a Martini style action. 8.15X46R. The bore slugged to 0.314" +/-. I had Accurate Molds make up a mold catalog 31-170L that drops a slug weighing about 180 gr. using 20:1 alloy. I had the top band set at 0.306" which was about bore diameter. The second band at 0.314" and the remaining five bands at 0.316". I run it thru a 0.315" sizing die when applying the lube. I set it out quite a bit and the OAL is 2.480". This allows the bullet to fill the long throat and center it in the bore. I'm using 21 gr. of BH209 as a propellent and Fed 215M primers. Velocity has been very consistent around 1,380 fps. Two, 0.060" veggie wads are used to eliminate air space. I was fortunate to acquire correct RWS cases and also have some made up from 32-40 brass (no I did not do that!). Accuracy at 100 and 200 yds has been excellent. I was very surprised how good these old rifles will shoot. I had a stop-ring mold, too, and tried them with IMR 3031 with poor results. Maybe I should have tried 4227 Mike.
