On the IMR4895 43gr load, I would investigate around that one a little more. I would go .2/.3 below and .2/.3 above and shot 5-10 shot groups. I don't know what the min is for IMR4895 but if it's lower than 43, you might want to take a look at it any way just to see.
That 2000-mr load is looking good. I would probably do the same as above with it as well.

I'll do just that. I wish I could get better grouping with a hotter charge of 2000mr, but my rifle may not do it. 46 grains is still sufficient for hunting so I'll see how it works out. I have a whole pound of the imr 4895 and will look into the 43 grain load more. IMR lists 42.7 as min with a 165 grain bullet.
I also loaded some of the 175 Bergers tonight with 47-48 grains of 2000 mr in. .5 increments. It's a nice looking bullet, so I hope it shoots. My seating depth is max for my magazine at 2.877. The longer coal seemed to help with this powder.
For my first round of rifle loading it's been fun and I've learned I may not be the right person to play with this new powder. I've had fun, but have run through 100 bullets in no time!!
My uncle has 8 lbs of free (to me) IMR4064, so that may be what I focus on with the Berger hunting bullets. Should be easier to nail down a. Load with more data available. Thanks for all your help.
Oh, and I was shocked the 110 grain vmax shot near an inch with 50 grains of 2000mr...that's got to be pushing 3200fps!

Yeah, I would probably do a bigger sample size per charge. Like maybe a 5-shot group. Just to make sure.
Never know, that 4064 may be the powder your gun really likes. I'd try it out too.

Western Powders' burn rate chart at www.accuratepowder.com/wp-content/uploads/2010/12/burn_rates.pdf places PP 2000-MR at the same rate as H380.
I was shooting at 100 yards. I'm embarrassed to say I don't know my rate of twist, but it's a stainless ruger mk2 model 77. The vmax kind of surprised me, I loaded with the 50 grain charge not expecting it to do anything but shoot fast. With some refinement it should do an inch or less which I consider good for a smokin' lightweight round. Now if I could only get the 165's or 175's to shoot as good! If I don't have any better luck tomorrow at the range, I'll find a good load with imr4064 and the 175 grain Berger VLD. That should be easier for an ammature like me to nail down.
An Alliant tech stated a little slower than RL-15. That is what I used to develop loads in the 8x57.
I have little experience with H380. But my work with Pro-2000MR, shows it's tracking right along with IMR-4007SSC, charge for charge velocity wise in the 8x57 FWIW.

Made it out to the range today and with 47, 47.5, and 48 grain charges seated out at 2.877 which is as long as my mag will allow, they still don't shoot like I want groups are consistently 1.5-2". I didn't try around the 46 grain charge because it's a fairly light load and I can get better accuracy and speed with imr4895 or 4064. I'm not sure but I would suspect that I'm not doing something right with the overall Langton or something. I'll still explore some more with the 2000 mr, but for now I have found a good load using 175 grain VLD's and imr 4064 so that's what I will focus on. The pic is of 43.5 grains of 4064, which is plenty accurrate for hunting.
I have had several of the 2000 mr loads shoot two holes almost touching but there is always a third flyer that I'm fairly sure I'm not pulling. Thanks for all the help and I'll post back should I find a decent load with th2000 mr.

That's a pretty good looking group there. I know not with the 2000-mr but still a good group to go hunting with for sure.
Are shooting from bags or bipod or full out rest?

"Lead sled" style full rest. Made by stonypoint I think. I'll use the 2000mr to play with until I'm out. Again, I think if I backed off to 46 gr I could nail down a load, but honestly if I'm not going to get the added MV then I'll stick to 4064...mainly because I have so much available. Most of my groups are consistent, yet large. From time to time I can feel when I pull one, but other times I feel like everything was just perfect yet the third shot is off by 1.5" and not in a pretty triangle. I've shot some of the charges three times now just to rule out shooter error. I ink I'll load a couple more of the 165's with 2000mr at a hot-but not max load with a couple different seating depths. I haven't yet tried below 2.80, so who knows...maybe my gun will like more jump with this bullet and powder combo.
My original 50 grain group was close enough to refine for hunting IF I can shrink it down a bit with a different seating depth and standard primers.

Finally got a decent group at about anime with 47.6 grains of 2000mr. Problem is I think I over tightened my stock after breaking it down to polish the trigger some more. Muzzle velocity was 2710, 2715, and 2737. I'll try to duplicate that
Pad and hope it holds after readjusting the stock.
Odd thing was at 50 grains I had two shots at 2801 that we're touching but the third was 4" away at 2795 fps. Now that I'm out of 165 gr bullets and almost out of powder I'll have to wait til I find more to proceed.

Check Ft Thompson. Last time I was in there, they had a bunch.

I think that's close to my load for 175gr SMK. 47.5, but, 47 was a good load as well. Actually both loads were pretty dang close, so I went with the hotter load to get a touch more MV.
