    Just bought Bergara Ridge, in 7-08. Picked up a few supplies today, 150AB, 150 smk, 139 Interlocks.
    Powders, Imr4350, 4064, RL17I
    Want to load up some tried and true loads, to run this thing through its paces. I'm a seven mil kinda guy, have never owned a rifle in this caliber, but everything around it. Put a Meopta Optika6, 3-18x50 glass on it. Load info for RL17 seems very low on Alliant website. Also have Varget. Thanks to all in advance.

    Grab a Lymans manual and work up.

    I worked my hunting loads for 7-08 up a long time ago. I ended up running 140gr bullets. Using PP 2000MR I got loads in the range of 2900 FPS from a 25” barrel that met my needs. I loaded 100 in new brass and still have several boxes. Haven’t loaded for it in yrs.

    I found 4350 to be too slow for the 140s, but it may work for the 150s if you can seat them far enough out to get enough in the case.

    Never loaded with your other 2 powders, Varget is probably too fast for the 150s.

    In a repeater I think the 140s are a better choice than the 150s. Less bullet in the case, little faster, little flatter, hit deer just as hard to 400-500 yds. My loads are 140 SGKs and 140ABs.

    I use varget for my 7mm08, with 140 class bullets i have found 41 to 42 grains works well in my rifle using lapua brass.

    My 7mm-08, turned 7mm-08AI liked powders in the 4350, H414, RL17 class burn rates.

    My top velocities came with RL17.
    My lowest ES(6)/SD(2) came with Alliant Power Pro 2000.
    I always wanted to try Ramshot Big Game, but finding it in my local area is spotty at best.

    I did try RL19 with Sierra 160gr HPBT GameKings. Had to redo my ladder test at 300 yards as at 150 meters left a 10 shot ragged hole.

    I used my Stevens 200 in my first F-Open match. Was all i had.
    Shot 173, 173-1X, 173-2X.
    This using 140gr Berger VLD-H over PP2000.
    Cases were prepped PPU.
    Fed 210M primers.

    Shot a doe with same gun/ cartridge setup the other year. 413 yards, 18°F, 1,923 ft elev.
    Somehow she turned 180°, and ran 20 yards before dropping.
    Berger performed exactly as advertized.
    Went in about 2 inches and came apart. Both lungs destroyed. Heart in 2 pieces and consistancy of mush.
    Found jacket under hide on off side.

    The BT will no doubt perform well. You'll probably have an exit wound. Note, don't hit bone with them.
    Had smallish buck slightly quartering away. Good broadside shot going in, but hit shoulder going out. 125 yards. Picked deer up & literally threw him about 10ft.
    You could put your fist in the exit hole. Whole shoulder ruined.

    Great Info, and thanks for reply. Probably will use 120TTSX, or 140, (139), bullet for hunting. Wanted to play with 150 match bullets in off season, if the gun likes it. Heard that RL17 was promising, bought some as well, but info, even on Alliant website is a little to be desired. Barnes loading manual lists it though.
    I hear ya on the Nosler bt though!

    With the mono bullets, i've found 2 things.

    They like a jump, or running start to the lands. Most manufacturers recommend 0.050" off the lands.

    While they don't say about it, i've found it helps to crimp.
    My theory..
    The crimp helps keep the bullet in place for that fraction of a second to help pressure build before the bullet starts moving. Helps with that running start.

    Friends of mine have gotten excellent accuracy with the 120gr TTSX.
    Performance on deer has been sadly lacking though.
    One in particular had been hit well, broadside at less than 100 yards. Pass through both lungs. Just missed the heart. Deer ran about 1/2 mile.

    I can check my notes on RL17 and PM you if you'd like. I don't put my charge weights out on public forum.
    Bear in mind, they will be for the AI, not standard 7mm-08.

    I have been using the hornady 139 interlocks since 1984. I currently own 3 7mm08s and they all use the hornadys and varget.
    Never had a reason to change. The 139s plain work!

    Yes they do, and darn accurate too!. Had a .308, that eould shoot them into a hole, and anchor deer to their tracks. Love this caliber, and rifle.

    4064 really shines with 139s in 7-08

    Hmmmm.......

    Either the AI gave me more velocity than i gave it credit for.
    Or the slower burning powders did it.
    Or both.

    Stevens 200 with 22" barrel.
    PPU brass.
    Fed 210M primers.
    140gr Berger VLD-H.
    RL17 gave 2,916 fps.
    Alliant PP2000, H414 gave 2,832 fps.

    As i mentioned, i always wanted to try Big Game, but was not readily available.

    I was going to add earlier, thst I learned this trick, years ago, especially with Barnes TTSX, and LRX bullets. The crimp really makes a difference, in accuracy, and burn. Just enough to bite into the ridge, but not too tite.

    It was a conversation starter.

    I should note, those velocities were my most accurate nodes. Not my max velocity.

    Alas, after about 6,000 rounds the throat is too long to seat the 140gr Berger VLD-H out to the lands. It was long throated to begin with.
    Rifle now wears a 24" E.R. Shaw barrel in 250 Savage. Was an over run special for $100.

    Did a little shooting on friday, mostly shoot and clean, with factory, then shot shot four samples. Didn't like anything with varget, however, shot a load with RL17, and Nosler AB, 150, first three in a hole. 4-5, close. Just under 3/4. Will revisit that load, and retry the other bullets with that powder. Showing promise!

    You might like trying VV-150, my 7-08 heavy barrel Remington 700 shoots 5/8” groups with Hornady 162 gr. A-max and Sierra 168 gr. hpbt Match. Shot one 5 shot group at 200m that I could cover all five holes with a nickel. I was going to shoot a 10 shot group but after 5 shots I couldn’t see any change in the target. Thought I better take a walk and see what was happening to the bullets. At about 20’ I saw the group, I quit at 5 shots, that was good enough for me. Haven’t shot a group with it since. Well, I did one at 900 yd, but that’s a story for another time.

    I have been out of the shooting world a couple or three years, my loading room is a disaster the river backed up with ice in February of 17 and my loading room got flooded and I haven’t been in it since. Plugged the chargemaster in to let it warm up why I got some stuff ready and in about a hour it was dispensing 39.5 grains of 2000mr with no issues, I double checked the weight with a tuned 10/10 and it’s right on! Was very pleased!.... first group with new brass in a factory other than the stock Tikka T3 lite in 7-08 went .316 Cc three shots ! I know I should being doing 5 shot groups but it’s always shot the load well I was just out and got tired of shooting factory 140 loads so I was happy.
