I think youll find the 4350 right on the money...if you have cci 200 primers start with those and .002 under loaded neck size for neck tension.
gunrack please do im interested to see/hear how it shoots.
Without a lot more info on what your rifle specs/ammo specs/scope & mounts it's hard to say.....however, I have to agree with some of the other posters, that my 7-08 was one of the easiest to work loads up for. Factory 140gr fodder shot inside of 1.5" @ 100yds. Winchester brass and primers with Remington Cor-loks (140gr) over 47gr of W760 .030 off the lands printed .75" and Barnes 140gr TSX over 48gr of W760 .050 off the lands printed .348" groups all at 100yds. Let us know how things work out. Deffinately would recommend scrubbing your bore really well and see if it might be oversized or shot out (no rifling left).
RL-17 is not the same as the other reloader powders. You are correct that some of the others especially 22 are VERY temp sensitive. RL-17 is not made in the same factory or by the same process I use it a lot to load for my 300winmag and 3 others. None of us has had any temp related issues.
There are 3 kinds of people in this world. Those who can do math and those who can't
My problem with rl22 was not with cold but with heat. I was at a varmint silhouette shoot a few years ago shooting a 25-06 imp and had zeroed at 300 meters at 7am. @ approx 55 degrees.
I shot at 11am the temp was close to 80 degrees at that time. My POI had changed by close to 6in. I switched to H4350 and this problem virtually disapeared.

Man thats huge...i havent have that issue with the RL-22 but now that you have said that im going to do a little testing like i did with the RL-17...put one round in the sun one round in my truck and one in my lunch box on an ice pak for 5mins then shoot all 3 rounds back to back at 200yds...ill post up with the results.
Had a chance to shoot a few rounds today but it was not ideal conditions at all. Temp was 55 degrees and cross wind at 8 gusting to 11mph. Trying to upload pictures right now.

Didn't take enough bullets but there is nothing there anyway unless someone can tell me what's up.

personally id load up the 150g nosler load at 44.8 45 45.2 with a different primer....id shoot 3 each at .005 off the lands and 3 each at .010 off and see what happens...the first 9 shots are going to tell you if you need more or less powder the second 9 will tell you if your seating depth needs to be changed...the raeson i say a different primer is because it dont look the WLR are going to work and also because ive had my biggest ES's using winchester primers in everything ive tried them in...personally my best results have been with CCI primers.
Thanks LongRange, the 150's clearly shot the best but I didn't know where to go from there. I had one of the primers snap on me today and I just loaded them last night. They look a little discolored compared to the brass. I have several fresh boxes of the CCI's and will load up some of those. I have already thrown the Winchesters out after they snapped on me. The primer pockets were good and clean.
The Lee book has the max load at 46.5 of the IMR4350. So I have a ways to go if I have to.
You say snapped? You mean they popped off when you were priming your cases?
I used federal primers for a long time then all the sudden started having fliers and inconsistent groups with known loads so my buddy gave me a 100 cci200s and a 100cci250 and said try these so i did and have been running them for the last couple of years...i may have just gotten a bad batch of fed210s and fed 215s i dont know but i like the ccis. I also never seen the need to pay twice as much for bench rest primers until i bought a box a couple of weeks ago,ive shot 150 of the cci br2s and am pretty impressed so far but ill let the crony tell how consistent they are this weekend.
After you shoot those loads let us know how it worked out.
Gotcha....yep ive had several of those with winchester and remington and remington i had 5 or 6 in a batch of 50 rounds so i rarely use them any more. The only primers ive used without a miss fire are the feds and ccis.
The best powders/accuracy with 120g NHBT/140g NHBT/139g hornady in my 1/9.5 twist savage are imr4320/varget/h335/w760/blc2/h380.
imr4350, CFE, 2700 are at the bottom for accuracy & speed I want.
My go to antelope load is the 120g nosler HBT in front of 44g imr4320.
I am late to this but I think I will pile on. You have too many projectiles. You need a method. Get a box or two of 140's like Hornady Interlock SP's or SGK's. Grab a powder like R15, H4895, or some 4350I never tried R17 in a 708 but I have seen some awesome velocities out of other cartridges so W T Heck. Do a ladder or OCW test. You can start at the manufacturers suggested COAL or at the lands. Load in increments of .3 grains or their a bouts.
Not to sound smart but I have a method and the reason for too many projectiles is that it will not shoot the light stuff. I thought I explained all that on the first post? I have shot all the factory 140 stuff that I can order or pick up. That and the fact that the bullet and barrel manufactures say this twist rate barrel should run 140 grain and above bullets thus the reason for going to a heavier bullet. The loads I loaded up and shot were just in effort to find a projectile that hopefully would shoot a little better group they were all loaded with starting loads out of the manual for each weight bullet. Now I plan on getting to one bullet and work the ladder test from there. I have three powders and if one of those does not get it then it's just going to shoot what it shoots. All three of them are in my loading manual so one of them is bound to work out I just haven't gotten there yet.
Thanks for the suggestions.
Everyone I know that has used Varget with a 140 grain projectile has had to load them above the maximum published powder weight to realize great accuracy. Like 42-44 grains. The IMR 4350 has seen some success around 45.5 - 46 grains behind the same weight class. As for the 4320 ?
Some bullets are sensitive to seating depth Have you contacted the bullet manufacture for suggestions, Hornady provided me with some helpful info. Seating the bullet too close to the lands produced large groupings, correct seating depth produced sub MOA groups out to 200 yards. Admited I was not shooting a 7mm-08 but there ya go.
