Many are now using Lee Factory Crimp Dies (FCD) to add varying amounts of crimp.

Has anyone tried the .308 160 grain HH in 300WSM and results?

Yes Crimped. I like to crimp the small cal. Bullets.

The following 75 gr Hunter loads were fired in a Savage 110E SA, 22" Preferred Barrel Blanks barrel, 10T and 5R rifling, chambered in 250 Savage Ackley Imp. Lapua 22-250 brass fireformed to 250AI. CCI 200 primers. 75 gr Hunter @ 2.407" COL None of these loads showed high pressure signs but were on the upper end. The largest group was .755" with SW Precision powder and wont be listed. No other loads were over .5". All things were the same, just different powders tested.

IMR-4166, 41.8 gr
3373 FPS, .500 group, ES 1, SD .4

Reloder 15, 42.5 gr
3392 FPS, .277" group, ES 62, SD 43.8

IMR-3031, 40.0 gr
3563 FPS, .196" group, ES 9, SD 6.1

N-540, 42.0 gr
3396 FPS, .097" group, ES 17, SD 12

W-748, 42.0 gr
3365 FPS, .397" group, ES 31

Looks like you've got excellent results there. That IMR-3031 load is smoking and tight.

I had a 243 that had a love affair with 3031 years ago so I thought Id try it again. Was having trouble grouping with slower powders with the 75 gr so I went to the fast side and it paid off.

Yesterday I noticed that the crimped ammo had a significant increase in velocity spread unless my LabRadar was acting up. Interestingly enough, the ammo still grouped well at 400yds.

That's odd, Usually it works the other way

The readings were suspicious especially since the ammo grouped well. I'll give it another try next week. I did see a 50 ft/sec swing which I never saw before. I can generally maintain single digit SDs.

I realized I have hardly submitted any of my load data.
Here is an INCOMPLETE spread sheet I have started.
I will continue to update and add to the group.
Apologies for the delay.

I get the message above when I try to open the link

Went to range today to test some groups in my 33 nosler with h1000 and r16 running right around 2,800fps. Was getting less than expected accuracy as I shot just to realized the actions screws had loosened. They were torqued down, this time they are getting some lock tight added.

This is only usable info I did get of labradar:

Temp 75 deg. / humid

The h1000 78.5 grain:
2767 fps
2774 fps
2777 fps
2766 fps
2748 fps
2787 fps
2736 fps
2787 fps

All were loaded to 78.50 to 78.48 grains
So wasn't a difference in charge weight.

So will only be trying R16 70.5 gr. Load for groups next range trip.

Don't know if this helps but just adding as much data as possible.
