New powders for 7x57

With the demise of H414, H4350, IMR4350 and Accurate 4350 - can anyone recommend any Reach compliant powders suitable for 120-150 grain bullets for a modern 7x57?
 
IMR-4451; Lovex SO-65; Alliant Re16; Viht N555 and N160; Ramshot 'Big Game' and 'Hunter'; Reload Swiss RS60 and 62; Norma N204 and URP. Lovex SO-70 (the onetime Accurate Arms 4350) should fit the bill, but my latest batch is apparently much slower burning and closer to the 4831s than 4350s. However, 7X57 has enough case capacity to hold enough of it to get a decent result.

As @big ears says, RS62 is a near perfect match to H4350 and usually the easiest choice to get a good load vice this powder.
 
I know this is an old thread but has anyone tried N550? Or The N555 in there loads?
I see that some here are getting good results with the N150 as well as the N140.
Cheers
 
Just done a bit more looking into this. (By the way its 160gr Partions not the 150's as I said above).
Using Gordans reloading tool.

N550 Barnes 120g TSXT BT @45.5gr its coming out at 2805ft/s warning signs not showing till 49gr and low burn rate at 44.5gr
So theres a nice copper option.
With this I can use up the last of my 139g SST. They show at 47gr warning, at 46gr they come out at 2821ft/s
Last my boar load 160g partions show. 44.5gr warning. 44gr they come out at 2455ft/s just under the legal boar round for france.

N555 data
The Barnes 120's TSXT giveing me low burn rates and warning's across the range.
The sst 49.5gr Warning. 48.5 they come out at 2761ft/s
The partions 47gr Warning. 46.5gr they come out at 2409ft/s (Not ideal for France need 2500ft/s)

Also ran the N150 which are as follows.
Partions 42gr Warning. 41.5 they come out at 2331ft/s (Not ideal for France need 2500ft/s)
SST 44gr Warning. 43gr they come out at 2710ft/s
Barnes 45.5gr Warning. 44gr they come out at 2956ft/s

Last of all
H super premormance just for the 160g partions 50gr warning and 49.5 they came out at 2495ft/s (getting close)

What do you guys thing?
 
Just found the below data in another post looks like Im sweet with all of these powders.

Sanglier (wild boar) 2,500 joules w/bullet 10-19 grams equates to 154 to 293 grains and 1844ft/lb
Cerf Elaphe (red deer) 2 500 joules w/bullet 4.5-6 grams equates to 69 to 92 grains and 1844ft/lb
Cerf Sika (sika) 2 000 joules w/bullet 10-19 grams equates to 154 to 293 grains and 1475ft/lb
Daim (fallow deer) 2 000 joules w/bullet 6-10 grams equates to 92 to 154 grains and 1475ft/lb
Chevreuil (roe deer) 1 000 joules w/bullet 6-10 grams equates to 92 to 154 grains and 737ft/lb

Ill have a look at the N140, but I think I read somewhere that it runs hotter/burns barrels out quicker.
