Just use the data for 180 grain bullets and work up slowly as you should every time.
I load the 175's in 2 of my 300 win mags,,they like to be seated about 50 off the lands.
I will tell that the LRX bullets work great on game,,I was all torqued out when we had to change to copper bullets here in California,,but after shooting the Barnes I'm really very impressed.

I just finished load development for 300Wby using 175 LRX.

No game taken yet. Accuracy is very fine.

A little practice needed for +300 yards to get hold overs for the duplex reticle unless I change the scope for one turrets.

I agree with the setback from the lands. First attempts didn't work until I stretched them out.

I agree that the 180gn Nosler E-Tip (lead-free) is probably a safe place to start.

Figure out you max COAL (mag load or single) and I am willing to put it into QL for a sanity check.

Does anyone have max length of case with bullet?

just looked at my hornady book ...


It says for 178-180 grain bullets (this is 175)

COL is 2.840" (should I use same for LRX 175?)

I got IMR 4350 and Hornady specifies

Min is 2600 feet per second 57.2 grains
Max is 3000 feet per second 66.5 grains

What do you think. I was thinking of starting at 60 grains and going to 65 or so to develop a load? Thoughts?

The data for I 4350 and the 165 is 60 to 68. The data for the 180 is 57.5 to 65.5.

You will be plenty safe starting at 60 and I would think 67 would be closer to max but you will have to see in your rifle. The bearing surface of the LRX 175 is approx. .477" the bearing surface of the 180 is .565. I don,t have a 165 ttsx but I would certainly think you could use the data for it. It probably has a similar bearing surface. The 150 has a bearing surface of .360. 2.840 is the minimum length in the Barnes #4.

Good luck and shoot straight.

Barrel length?

 

[yuflesh]

26" barrel. Rate of twist 10

According to the Barnes #4 you'll get 3148fps max with the 165/168 and 3003fps max with the 180 both with a 24" bbl.

Shoot straight
