Got some off the shelf. South of the Bombay hills though, so I guess I might be being a bit harsh on you.

Was there any more there?????? Do they have a website???

Nah. Just one box. If they don't work for me, you can have the residual.
Cheers

Bryan Litz has published some data on "real" BC's vs the exaggerated BC's claimed by Nosler. This is older data so might be more around now.
Also very interesting comments about twist rates needed to stabiliize these pills

Interesting. My 1/10 twist .270wsm falls into marginal for twist rate, so I wonder if its worth the bother?

I think you 1:10 should be OK as my Finnlite 270win is the same.

Have shot a lot of animals with mine until I got a 300 blackout.

Here's another is a link to one of my old hunts with the LRAB's

You are a good man B.

PS, I've given up with the .277 LRAB, spending all my $ and time on black rifles instead.
Still haven't tested the 77gn TMKs on game yet though.

I gave the .270 150grn LRIB a spin today. (A7 .270wsm)

Used N560 and Hrbrid v100. Magazine length. Hit pressure pretty quickly with both. Came up with a workable load with each powder @ 3065fps. Would have liked 3100fps. Could try 2215 but don't want to buy any more powder.

Only 2 shot groups at 100yds, but bullets were touching.

I meant 2225 (above) to try. And LRAB (not LRIB).

Im getting really good speeds with 2225 and 150 VLDs, havnt shot the LRABs I have yet

Let me know how they go when you do.
I don't want to use too many for load development, because they are scarce as hens' teeth and cost gold. $147/100 delivered. I was shocked, but had to buy them just to ram one up dogmatix.

I'm a bit disappointed with 3065 fps with the 150grn LRAB (270wsm) I'm getting, that's right on the pressure limit (one grain higher gives ejector marks). Quickload told me (@64k psi) I should be close to 3150 with N560, and QL is usually on the money.

I'm wondering about 2 things. Firstly, maybe the long bearing surface of the LRAB pushes the pressure up, or that I would do better using Norma cases that stand a bit more pressure, rather than Remington that I'm using.

I guess a third thing is that I could try a slower powder, but apart from MRP and R22 which you can't get, N560 is the best option on Qiuckload. 2225 (Retumbo) and 2217 are both down around 3k. That's confused though by Ryan_S getting good speeds with 150 Berger and 2225.

Any thoughts?

Or should I just be happy, and go and shoot stuff?

I foolishly thought my amax (162gr) charge would be a safe start charge for the 150 lrab and hit pressure, they seem to take a fair bit more force to get down the barrel than the amax regardless of the weight difference

That's a curler there @Tahr, with the BC of those projectiles even poking them out at 3065 you're equiped to do some damage out to very far away. With my 20" barrel 270win I had them stoked up reasonably warm over 2209 and was putting them out at 2850 and they carry plenty enough energy out to further than I'm prepared to shoot in most cases. Is your barrel factory length (24")? It's an A7 right? So I'm assuming very similar barrel to my 85. I'm getting 3180 which is fair steaming along, have confirmed drop using those numbers out to 600yds so I'm pretty confident everything is correct. I'm using Norma brass though so I'm gonna hazard a guess that I would be getting pressure using any other brass.
