Update:

Had a baffle strike in my suppressor, and the only thing I had been shooting that day was 110 V-max's supersonic, and 90 XTP's subsonic. The 90 XTP is the shortest/lightest bullet you...

150 Nosler Ballistic tips are the worst yet. They are unstable at 1300 fps, and from 1050-1200 fps, they are hitting the target at about a 45* angle. Shot some more of the 208's today at 100 yards,...

I've documented a lot of it in this thread, but I'm using AA1680, VVN110, and Alliant 2400, and I've tried everything from 900-1200 fps. I've tried lots of combinations/charge weights/etc., burned...

Even 168 SMK's were not 100% stable. I know what you mean about the 208's! I bought 500 of them for $20/100 when Midway had its' last big Blem bullets sale. Thanks for the offer on the lapping...

I've used 3 different powders, at many charge weights, trying many combinations of bullet/seating depth. So far, the only bullet that appears to work in this barrel is the 208 Amax. I took some...

Update

Got the new stainless barrel from Douglas. Other than being stainless, the specs are the same, it's a 10" with 1 in 7 twist. The results are looking better, but I'm still not sure. I have some...

While we are on the subject: CAN a nitrided barrel be machined, or is there some type of preparation to remove the nitriding before machine work? As an example, say I wanted to have a different...

I don't think so. He was pretty upfront about everything. He just said I was the first person to have an issue, probably because I'm one of the few people who didn't go stainless. Either way, I'm...

Update

Just got off the phone with Stan at Douglas Barrels. Good people. He said they don't make many of the fast twist barrels in chromoly, 99% of people order them in stainless. Because of this, their...

They are the only bullet I've used thus far that will not feed from the magazine. 16 grains of VVN110 gets it to 2000 fps in a 10" barrel. OAL is only 1.65". This would be a pretty neat load if it...

I know everyone has seen a fired bullet, but I thought I'd throw this one in for a head to head comparison:

208 A-max recovered from 30/221 Shilen barrel. Note nice clean rifling:...

It's tough to tell what's going on unless you can look at them up close and run your fingernail over the grooves, but I've tried to point out what's going on:

Bullets were going into the sand and then turning sideways, so half of the bullet is "sanded" rough, impossible to see rifling. It's tough to get any data out of the 4 bullets I recovered. I called...

Going to get a couple bags of sand and headed out to the range. I'll catch a few bullets and see what they look like. Barrel is a Douglas.

That's the best I can come up with.

Looking back at all of my data:

175's need to be going 1500 fps to be stable.
110's are stable down to 950 or so.

Plugging these numbers into JBM's...

I slugged the bore, but I'm not sure what it's telling me. From land to land, it's .306. From groove to groove, it's .308. This seems normal to me. Everything looks uniform all the way around. ...

Also, I'm sending my 1 in 8 twist barrel off to Hoser sometime this week. He is our resident ammo expert, so maybe he can come up with something that works. I'd really just like to get this figured...

I shot some 160 Hornady FTX bullets today. They are the 30/30 bullets with a rubber nose, and are fairly short. I only tried 2 charge weights, and ended up around 1200 fps. They were stable at 50...

Different twist rates, so no. My machinist said the barrels were well made and couldn't find any faults, other than the bores were a bit bigger than expected. Usually a .300+ gauge fits very snug,...

I've tried a fairly exhaustive list of bullets/speeds mostly at 100 yards, a couple at 50 yards. I get the same results with both barrels. There is something wrong here. If I didn't have a...

My last bit of hope was 1680 powder. I tried it this morning and I'm still getting understabilized bullets, of course. It's also too slow for my rifle. I had a couple cases that were covered in...

Good idea. I did it that way, five times in a row, and all 5 measurements were really close. I took the average of those and ended up with about 8". Still, there has got to be something else. ...
