My apologies. I actually don' have an original thread.I didn’t see in the thread where you stated how much bigger your groups were before so hard to gauge what improvement your recognizing. Something I have found in my 7 mag with a 9.5 twist is it does not like the long skinny high BC shaped bullets. So a 150 silvertip might shoot great out of it but a 155 terminal ascent is not great. In theory the twist should stabilize up to a 168 grain but that the shape has definitely had a big impact on accuracy. The bullet stability calculator on Berger’s website kind of put it together for me when I looked at my log of what ammo shot well and poor.
On a factory 700, this doesn't surprise me. My Father in Law has a Sendero that he runs 130's through with just absolute stupid accuracy, but anything above about 140 doesn't shoot worth a darn. My dad's 700 from the 80's taps at about 150's. Heavier stuff doesn't shoot well. We aren't sure why, but in our experience, the factory 700's just don't really like the heavy stuff. My grandpa and uncles have experienced the same. Kindof weird I know, but just want you to know you're not alone!Thanks for the input everyone. To answer questions, and also provide an update:
- I don't have much much trigger time behind magnums, but with the muzzle brake recoil is quite mild. I am genuinely not concerned about my form, though there is always room for improvement
- I have cleaned the barrel thoroughly with a copper solvent
- The rifle wears a Nightforce SHV 4-14x50, and this is the 3rd scope I've had on it
NOW, for an update:
Following the advice of a hunting partner, I took out all the action screws and re-torqued everything. Torqueing the front action screw down first, I got everything as close to 65 in lbs as I could using a FAT wrench. I then hit the range again. The results were somewhat surprising:
- Winchester Supreme X 150gr Power Point (by far the cheapest ammo): .5" cold barrel, .75" hot barrel
- Winchester factory loaded 168gr Accubond LR's: 1.2" or so
- Federal Premium 160gr Partitions: 1.75"
- HSM Berger 168's: 1.5"
- Norma Professional Hunter 156gr Oryx: 1.25"
Maybe this gun just likes the lighter bullets? I allowed the barrel 2-4 min to cool between each shot, so I don't think a hot barrel is the culprit. I'd prefer to run heavier bullets, but for my goals it may not really matter.
That’s odd that the rifles like the lighter bullets. My Tikka 7RM SL does not like the 140 or 150’s but really shines with the 160’s. Barnes TTS factory loads.On a factory 700, this doesn't surprise me.

If you want a new gun, buy that Bergara and have at it. There's not a better factory rifle on the market. But if you've got the money, have it rebarreled with a Remage barrel nut system and run it. That action is a great blank canvas for sure.
And also, you said it's an older gun, is the barrel shot out or pitted from rust and misuse maybe? I'm sure you've inspected it, just trying to throw out suggestions?
Yup, odd in deed. In our experience, the Remington 7 Mag's just don't like heavy stuff. We've seen it on several different examples. Not sure why, but that's what we've experienced.That’s odd that the rifles like the lighter bullets. My Tikka 7RM SL does not like the 140 or 150’s but really shines with the 160’s.

I recently bought a Browning HC LR (not McMillan) in 7mmRM. Did the tedious break-in: shoot/clean x 20 shots, shoot/clean 2 rds x 5, then shoot/clean 5 rds x 2. Clean, then shoot fouling shot. My 15 y.o. and I shot 5 rds at 200 yds using the crappy Wally World ammo and our group, combined, was way under MOA. I was shocked. My last two rounds were approximately 1/4”. Since we were doing break-in, I did not have my calipers to measure the group. I hope the Hornady Precision 162gr ELD-X shoots this well. If it does, I have found my forever elk gun! Worst case scenario, I know the gun likes the $22/box Winchester junk. Ha!
Seekins Havak PH2 or Christensen Arms Ridgeline. I just picked up a Christensen Arms ELR that is very nice but a little over the 2k mark. Good luck!I'm about at my wits end trying to get an older Remington 700 7mm Rem Mag to shoot. It's bedded into an HS Precision stock, has been looked over by a gunsmith, and nonetheless I can't get it to consistently shoot sub MOA with factory ammo nor hand loads. I have considered the fact that it could be me, but I get more than acceptable performance from many other guns and thus don't think it's just a case of me not being able to shoot.
In light of this, I am idly considering options for factory rifles. If I do pull the trigger on this, I'd like to buy it in February or March to have the summer to practice and develop a hand load.
My goal for this rifle is shooting out to 1000. I DO NOT plan to shoot that far at game, but I do want that accuracy for hobby purposes.
The stated purpose for this rifle is big game (elk size and larger) hunting out to 600 or so yards from a solid prone position, and practice oriented towards same. I chase elk every year in CO, and would also like to eventually expand into caribou and others.
This rifle will be topped with a Leupold VX-5HD 3-15x44 w/ HTMR that I already have.
Criteria I'm looking at:
- 7mm Rem Mag chambering (also open to 6.5 PRC and .300 Win Mag, but I'm already set up for 7 RM)
- 24-26" barrel, threaded for muzzle brake (if it already has one, even better)
- Under 9# preferred (for under 10# with scope and loaded mag)
- Factory adjustable trigger
- Synthetic stock
- Weather resistant finish (Cerakote, SS, etc)
- Remington 700 footprint/accessory compatibility desirable but not required by any means
I'm willing to spend up to about $2000 on this for the right, never buy again gun, but will of course consider something significantly lower cost. I also haven't ruled out rebarreling and restocking the current gun.
Some options I am considering:
Bergara Premier Highlander or Approach:
Think of our Premier Series as an extension of our Custom Series, but with standardized features for greater efficiencies in parts production and assembly - providing near custom performance at prices that are affordable to serious shooters.www.bergara.onlineThink of our Premier Series as an extension of our Custom Series, but with standardized features for greater efficiencies in parts production and assembly - providing near custom performance at prices that are affordable to serious shooters.www.bergara.online
Browning X-Bolt Hells Canyon LR McMillan
Long range bolt-action hunting rifle with premium McMillan Game Scout stock in A-TACS AU Camo, Cerakote Burnt Bronze finish on barreled action. Fluted barrel. Includes Recoil Hawg muzzle brake.www.browning.com
I have a few hunting partners who use Browning X-Bolts, and I've been impressed with what I've seen. In light of that, that rifle in particular has my attention.
With that said, I am all ears to others as well.
Thoughts and discussion are greatly appreciated!
