    Want to see whether the 300 WM is for me. Have decided to buy either the Remington 700 Long Range or the Model 700 5-R Stainless Threaded Gen 2. Expect either to be accurate and reliable. Want heavy barrel, muzzle brake and prefer 26" barrel. If the 700 Long Range is chosen, will have the muzzle threaded. Prefer the M-40 style stock. If the caliber works for me will probably move the action to a chassis. Any recommendations as to which of these rifles to chose is appreciated.
     
    Earlier this year, I bought a Remington Long Range 7mm Rem mag. It was the most inaccurate rifle I've ever fired. Since then it's been totally customized. Based on my sample of 1, I would steer clear of that model. 5r might be better.
     
    I have a 5r it shoots very well. You can also buy the action paired with an AI chasis from EuroOptic. My only complaint is the that the X mark pro while serviceable makes shooting the rifle well more of a challenge than it needs to be I would add a replacement to the cost of the gun.
     
    im shooting a Remington 700 Long Range in 300 win mag and love it.....currently sitting in an XLR evo chassis.

    shoots right around 1MOA with factory ammo.......will tighten up a bit with handloads.

    if you go the XLR route (or really any chassis route)....find a way to add some weight to it......i machined up a solid stainless buffer tube to add around 2 lbs. itll be tough to spot your hits through the scope otherwise, a muzzle brake will also help with this.
     
    i purchased the Gen 2 300WM and found out after the fact the barrel was not free floating after i got it home and torqued it back to specs( i had installed a Timney trigger) i had also installed a thunderbeast inc CB muzzle brake for my ultra 7. the store had me bring it back and wanted to charge me to bed the rifle to FIX the barrel not being free floating... i ended up buying a AIC AT stock from Midway USA. im currently shooting Hornady 208 AMP projectiles @ 2787 with 75 grains of h1000 powder. thats all i need for the range i have currently

    if i were to do it again id buy a kit from Euro Optics, i have been very happy with their service from another rifle
     
    I am on the same quest. I got myself a brand new Remington 700 Police (RR prefix) just last week. Im still wating some parts and reloading supplys but with a little luck, it will make it to the range next week.

    Since I'm willing to replace the stock with a chassis, was the barrel accurate enough or did you replace it as part of the customization?

    Actually, the barrel was the problem. I replaced the stock with a McMillan A3 and tried two proven scopes. Still a dud. I then took it to Phoenix Custom Rifles with a new Krieger barrel. They trued the action (Brad said it was actually pretty square for a factory Remington). He fitted the barrel, bedded the McMillan A3 stock I had tried originally, and now it shoots 1/4"-3/8" groups. I truly believe the barrel was the problem. It was shooting 2"-4" groups at 100 originally. That's was from a multitude of factory ammo and load workup with multiple bullets and powders. I literally took it to PCR and ask them to make it shoot, and they did. Unfortunately, it was an expensive learning experience for me. I'll never take a chance on a factory Remington again. You might get a shooter, and you might not. For me, it's not worth the chance.
     
    Just as an additional statement to my reply above, I have had factory Remingtons that shot well, but that was years ago. The 7mm Long Range model that I spoke of is the only factory Remington I've tried in several years. It was a 2017 model.
     
    I've got an old 700 Sendero stainless in 300wm that I really like and shoots well but you couldn't pay me to buy a new, off the shelf, Remington. Not with the offerings from Tikka and some other companies. Too many QC issues and by the time you get done replacing the stock and trigger and maybe the barrel, why not build a custom?

    Alamo Precision Rifles here in Texas just announced a pretty awesome barreled action package they're offering with a Curtis Axiom and one of 3 barrels they use for their standard builds. Not sure if they're listing 300wm but it'd sure be worth contacting Robert and asking him.

    A 5r gen 2 was sitting at my local shop. Threaded with break and timney trigger. Couldn't bring myself to buy it. Just cant get past the fact its a huge leap of faith on whether its a shooter or a dud. 10 years ago I would have bought it in a heart beat. Huge fan of tikka's these days. I have the t3 light, shot the ctr's and really want the Tac A1

    My Remington 700 SPS-V, bought in 2009, was hardly a shooter and rarely went below 1.5" at 100yds. Granted it was a 308, not 300WM, but what made it a poor shooter was what would apply across the board. I transplanted it to a B&C stock but saw moderate improvement, with groups measuring maybe 1-1.25" at 100yds. When I measured the throat to better reload for it, my measured OAL was in the 2.9" range for the 168 AMAX. Waaayyyy long. I took it to the local gunsmith and had him set the barrel back, but in doing so, he had to set it back almost 1/4" due to the fact that the chamber was almost .006" out of concentric with the bore. Pretty obvious whoever chambered it didn't indicate off the bore when he chucked it up for chambering. Once it was re-chambered, true to the bore, and with an M852/FGMM reamer, it shot sub-MOA easily.

    If I am going to get another R700, it will be an older one ... oh wait, just did that with a Rem 721 action in 270. Sent it to RW Snyder and he put a Krieger 1:10 heavy Palma on it and chambered it for 300WM.

    He's pissed at Remington because they wouldn't warranty his rifle, I can't blame him I would be too but problems can come from any manunfactor. Mine is averaging 0.6 moa with factory ammo (FGMM, Hornady 200gr ELD-X, ABM 230GR & 215GR VLD's) that's with 3rnd groups as I'm trying to get a sampling of accuracy and save barrel wear but it's enough to know that I've got a 300wm on my hands for a factory gun shooting factory ammo I don't think I could ask much more. The action is actually pretty sweet nicer than the Tikka CTR's that have a good rep for their action IDK if Remington uses tighter tolerances on the 5R's but compared to a more economical 700 like an SPS action for example feels terrible in comparison.

    If you were going with a short action I would recommend going a different route not because my experience with my 5r makes me think it's a poor rifle but due to the popularity of calibers like 6.5cm the short action market has exploded in recent years and a variety of rifle choices have come along which didn't exist in years past which encourages competition amongst manufactures. Short action rifles like the Tikkas, Bergaras, and many others are competition ready and all deliver alot for the money at a better price point than Remington who hasn't made serious entry into this new market which will reflect in the amount of love you'll hear for Remington. Take a Bergara HMR for example it comes with a mini chasis also the stock has better sling integration it's detachable mag feed, has comb height and LOP adjustment and can be had for $840 while the 5r has none of those options and I'm seeing the 300wm gen 2 5r for $940, I payed $1,300 for mine when the gen 2 had just come out. Back in years past if someone wanted an entry level rifle they'd buy a 700 and build on it and now they've better options and Remington hasn't made effort to keep up with the market but but these newer short action rifle options don't exist for long action cartridges like 300wm and if you want an entry level 300wm that's probably your best option, buy a 700 and build on it either that or go with a 6.5cm and another manufacturer. As mentioned EuroOptic has 5r/AI kits for $1500-2200 if you like the chasis or buy a factory 5r and sell the stock for $200 or so and buy whatever chasis you like you could also buy a trued barreled action it would up the cost though.

    Thanks for the responses. After careful consideration I purchased a Remington 700 MDT TC21 300 24 MB (84475). Should have it by late this week or early next week. Then the fun begins.
