So I bought some of these out of curiosity. I just guessimated around my 130gr Hybrid load and started with touching the lands. Warning* Don't assume that these loads are safe for your rifle.
Pressure test:

20181021_163808.jpg20181021_163200.jpg

45grs at around 3100fps showed a lot of promise but I didn't get any pressure signs from any of the loads. So I came back out the next day with just 5 shots of 46.5grs and got this result:
20181022_141908.jpg
20181022_140535.jpg

I was pretty damn happy with that but wondered if it was a fluke. So I loaded up 3 more rounds of the same and came out the next day and shot this:
15404282543371446261781.jpg20181023_180936.jpg

Needless to say they seem to be very accurate. Especially when you notice that during the pressure test that the POI of 44.5-46grs would make around 1" group. I'm impressed so far.

Lehigh website lists the G1 BC as .538

That's .072 less than the G1 of Hornady 140g ELD-M (according to their published BC's)

Figured it would be more. More in line with the Warner (.637 G1)

What is your COAL touching the lands?
when I load some more up I'll let you know. My 6.5 creedmoor is a .199 freebore with over 1000 rounds on it so I'm sure the lands have moved forward some. I can tell you it just barely fits in an AW magazine.

I don't think these were meant to compete with 140-150gr class of bullet. More so the the 120-130gr class plus it seems you can push these much faster without pressure. Basically competing with the 6 creed and 105gr bullets ballistically but more than likely better barrel life. Also don't think these were meant to compete with the Warner bullets since they are $60+ for 50 and the lehighs are $36 for 100. Not saying they are something mind blowing but they seem impressively accurate and judging by their consistency they probably have great vertical dispersion at longer ranges. I'll know for sure soon.

Nice...i havent messed with the 121s but i have shot the controlled chaos solids in 4 or 5 different calibers/rifles and the accuracy in every one of them has been spot on with your results, very easy to load for, great accuracy

I really like the fact that I didn't even have to do a full load development.... I usually have to search for a load that shoots that good.

Running them at 3100fps compared to my 2700fps 140 grain RDF load. These 121s smoke the 140s in trajectory and give up very little to drift. I’m going to pursue them further.

I’m wondering about the minimum velocity they recommend of 1500 fps. I wonder if they have trouble going thru transonic. Either way I’m good for 1000 yards where I’m at.

I think what they are saying is that they didn't design it for subsonics (which they are known for). Also because of their length they may not stabilize in a 8 twist with a muzzle velocity below 1500 fps. Like how 208 amaxs shoot great in 9 and 10 twist barrels but won't stabilize with those twists at subsonic muzzle velocities.

I ordered some tonight. I messaged Lehigh about load data, they were quick to respond. I like that. I’m going to try 4451 first.

Waiting on mine. I ordered 200 of them from midway, they were 50 miles from my house and decided to go 200 miles north for a short ride.

Just another option;

Lapua 123 Scenars

I am running them out of a 24 inch barrel and can get just shy of 3100 in a node.

As someone who shot a ton of solids, There can be some downsides going back and forth etc. Spotting even with a 338 LM can suck.

This is absolutely not a bullet weight I would want to use in a match.

The 123s are:
-Way easier to spot on steel than an equivalent size solid. They leave a nice traditional watermark as well as a good frag signatures, unlike solids.
-They mag load easy
- BC’s a little bit higher with a G1 547.

Not trying to hijack just toss another option out there. The OP shot a damn good group provided very helpful information.

I saw those Lapuas when I was researching the 121s. I ran the numbers and was equally impressed. I don’t shoot matches, I mainly shoot by myself or once in a while with a buddy. I have my own steel and keep it painted white, touching it up frequently. I’m not to worried about spotting impacts, I spot my own hits pretty well even with my 338. But I do get what you’re saying, and I’m interested in seeing what range these 121s start being hard to see the impacts.

When I get a chance I’ll dig up some video shows my 338 getting a place with Warner solids and 285 amax.

The frag or sprawl and the watermark reduction pretty drastic.

I’m leaving my club right now and today a 25 mile an hour winds kept us from seeing the impacts on an Silhouette at only 890 with 308 solids. Here is a video from only 700 yards.. We could "hear" the hit, granted the plate is very heavy so the center hit move it very very little, but we could NOT see the frag or watermark. But with a normal round, you would’ve seen the Frag and watermark fairly easy.

Here’s a shot at 2200 yards using 270 grain solid. Velocity is higher than the standard rounds. Notice how small the watermark is and the frag almost non existent.

Below is the standard solid at 200 yards further with a lower muzzle velocity and lower BC


I had a ton more videos somewhere but I can’t find.. while driving

My workaholic Bergara has suddenly lost some speed so I dont want to mess with it as the throat is worn, probably due to me not letting the barrel cool.

Im working on a build using a Nucleus action when that is complete I will definitely see what they will do.

The weather here is shit!
I’m trying to get out and test them.
I’m going to try 4451 first.
