Just curious if anyone has loaded these? Thinking about giving them a try. Anyone have a good load they are using?

Just got emailed some load data from Berger for both 168-175 grain VLDs. I will start monkeying around with loading soon I think.

I can post the two tables they sent me later if anyone else is interested.

Have you looked at the 210's?

Yeah I was interested in those, but think I might be a bit short on twist for them to work well.
Might still try them though, you never know.

IIRC Berger says minimum of 1:11 or 1:10

I like heavier bullets in the Weatherby to take advantage of the case capacity and the long neck. The advantage the Weatherby brings is the ability to push the heavies to good speeds. The only bullet I shot in mine for decades is the 200 NP with perfect results.

Anyway, the 175 will work fine, but the Weatherby will do more with the 190-210 at extended range, and have more bullet for closer range targets...all of these bullets are a good choice however.

Many Weatherbys were equipped with a 12 twist barrel, but at the speeds the Weatherby will drive them, stability may not be an issue...you'll have to try them out to see how they perform in your rifle.

I was thinking the 168 or 175 will give me a pretty good balace of bullet weight and flat trajectory, but I might just be reconsidering that now!!

Gadzooks! I didn't realize the B.C. was .631!!
Looks like only a half inch or so difference at 300 in trajectory and at 500 its still only about 3 inches. Crap I might just be going after those instead of the 168s or 175s

I know Remington's Custom Shop only offers the .300 Roy with a 1:12, but their own RUM in 1:10. I called foul, and they couldn't give me a straight answer, so I didn't buy their rifle. At .300 Wby speeds, it seems even VLD's should give an exit!

Having shot thousands of 168s from several 300 WBYs I can tell you that 1-12 twist WILL stabilize them, even the Bergers. It will also stabilize the 175 and 180 SMKs. Have never fired a 175 Berger myself.

I have NEVER found a rifle that will shoot the 210s accurately and know several people with the same experience. They are a different bird and take some work. A buddy has a 300 RUM that he had built and it would NOT shoot the 210 Bergers but shoots the 210 JLKs into .25 MOA. He has an 11.25 twist barrel. With a 10 twist, he might be able to shoot the Bergers too.

I have had the best luck with H4831 and SC version along with VV N560 with the 168s. My reamer is short throated so powder weights won't do you any good at all.

Bergers like to hit when they are going fast1!

My Grandads old German Mk 5 300 Wby with a 12 twist won't shoot hardly anything. But it does like 168 and 175 SMK's and H4831.

To date the only other slugs I've found it to like is the 165 Sierra HPBT and the 180 Horn.

Running a 210 Berger is definitely pushing the limits in a 12 twist and may not work in all barrels at all altitudes. If it's not accurate, twist may not be the reason, but the 208 A-Max has near the same BC on paper, seems to need less twist, and is easier to find a good load for...the true VLD designs like the Berger can be harder to find the right load in general.

Fortunately, Berger offers other choices that are more reliable in a 12 twist, the 185 is usually a good choice as is the 190. The 190 is a good LR bullet and should work in your barrel without a lot of drama.

In the Weatherby, H-1000... I can usually find an accurate load pretty easily with the heavies. I've not had to burn a lot of rounds to find a good load. The thin barrel benefits from a quick OCW load workup, but I keep load workup to a minimum.

The Weatherby is not for paper punching. Small groups are nice to see on the paper, but most very good hunting bullets are not target bullets. MOA accuracy, or close to it, is good enough. I am more concerned with consistent point of impact than tiny groups.

At longer range, terminal effects and better wind numbers are as important to consider as group size, so a slightly less accurate bullet with better BC and wind resistance, and having reliable terminal effects can make one feel better about their choice.

Not sure what you're wanting to do with your rifle. For LR I'd go heavy, but the Weatherby is actually a very versatile round, and has plenty of horsepower, so in ordinary circumstances, any bullet weight between 165 and 200 gr will work out very well.

For example, early on, for a general hunting load I used to run the 180 Hornady Mark mentioned over IMR 4350 to around 2950 fps...that's a light load in the Weatherby, but it was accurate and very mild recoil, but still reaches out. Up close, you don't want to push the Hornady too fast or it won't hold together.

Stepping up, the 200 NP doesn't have that problem...it's accurate, always expands, always penetrates, always holds together, has a high BC for a flat base, no special twist requirements...if there is a guaranteed do everything well, all range, all game, for that round, the 200 Nosler Partition is it...works well in the '06 too. 200 AB is another.

If I am going to be using bullets on the lighter end, 165gr or thereabouts, I grab a smaller rifle as well, but if the Weatherby was the only rifle I had, I could easily do everything with it...as it was, and as I did for many years.
