That is the kind of review that makes asking the question on these sites worth while. Thanks for that insight at this point I would rather stay with the 338 lapua pushing light for caliber HH's. With the Lapua, I have a wide selection of brass and the twist rate will stabilize a wider range of bullets. Same rough powder usage with a lot more advantages.
You hunting armored Tryanasaur? LOL I'd imagine a 338 LM would require a heavy rifle to manage that bad boy.
I did a quick velocity check on 166HH and 180HH today in my 30-378.
I have a 338 lapua that pushes the 260 HH at 2930 (if my memory serves me) and it is a pleasure to shoot. It is a 13 -14 lbs rifle.
That is pretty anti climactic!!! Why so slow??? I had others say that Weatherby rifles are more accurate at the lower velocity spectrum, but both of those rounds appear anemic with that much powder. We are pushing 180 grain accubonds out of a 300 wsm at 3000 fps. I would imagine with 180 HH I could get as fast as your 180 grain with 2/3 the powder.
Bought this rifle used and getting tuned into what it can do. Barrel has had some use.

I originally was looking at a 6.5x300 weatherby and / or another 338 lapua to push light for caliber bullets. Someone out in the innerweb suggested I look at the 30-378 as another option. I had never really considered that chambering, nor did I know that much about it. Thus the questions on a couple sites I belong to. At this point, I would say I am leaning away from that chambering for a couple reasons.One the guys I hunted with in Oregon used a 338-378. He was part of our group that spent 23 days hunting in Montana just before I moved to Idaho. I saw him take a nice whitetail at over 900 yards. That was John's goal - to be a long range hunter. So my question is what is going to be the purpose of a 30-378? What is your goal with the 30-378? Nothing wrong for just wanting the biggest 30 commercially available. From my research, I think if it is to be a long-range shooter, the 338 in several renditions will out perform the 30 cal. This is coming from a guy who shoots a 300 RUM. I wanted a 300 RUM again for several reasons. One was I never tamed the beast the first time I owned one. Second, I really like hunting desert mule deer. It is nice having a flat shooting rifle when there can be 600-700 yard shots. I like to keep them under 500 if at all possible. I must admit I just like shooting boomers!!
You didn't have a helicopter tag? Reminds me of an elk hunt. I spotted a nice bull grazing alone at about 1500 yards. It was an almost perfect setup. The wind was right, there was a 14-20 foot ridge I could follow out of his sight to get close. I carefully worked my way for about 1200 yards and then belly crawled to the top of little ridge and he ranged at 260 yards. I was setting up for the shot and a 4 wheeler came out of nowhere screaming on a single track. He was gone in a flash. Oh did I want to shoot a 4 wheeler!
Here are a couple pics. For reference, I am 6'0" 265lbs in this photo. Also a pic of the Lapua set up for when we were buzzed by the helicopter. The skull measured 20.5 inches.....he missed the all time book by .5"....story of our families life....Pics or it didn't happen...

There's your problem. That giant case needs way more barrel. mtmuley
