A: I don't think it will work but I suggest asking Remington Consumer Services / Parts & Service TEL: 1-800-243-9700 Fax: 1-336-548-7801

A: Hi Kevin, Unfortunately it won't work. You can confirm with Remington Consumer Services / Parts & Service TEL: 1-800-243-9700 Fax: 1-336-548-7801

A: Kevin, Remington says this Remington 700 Action Long Action Magnum is Compatible with 7mm Rem Mag, .300 Win Mag, .300 RUM, .375 H&H, and .458 Win Mag. I would confirm whether or not the 338 Lapua is with Remington at 1-800-243-9700.

A: It has the potential... a gunsmith worth his salt can do the machining required.

A: It will not work. The case head dimensions are different by .050" which would entail modifying the bolt head and extractor. Call your gunsmith before you proceed. You may want to look for a Savage action for the 338 Lapua.

A: Robert, "Long Action" Bolt will be optimum for the 300 PRC Build. https://www.americanhunter.org/articles/2019/1/18/head-to-head-300-prc-vs-300-win-mag/

A: Robert - I doubt you'd find one that has more engineering and field testing behind it than these. The Remington 700 is a 'standard' for reliability. Sounds like a fun project!

A: Robert, Head spacing will be a problem with this bolt and action on a 300 prc. The round is about 3.7" long. A .750 bolt with a ..532 to 545 standard magnum bolt face are used in most 300 PRC builds. A Savage 110LH or Tikka T3 or T3X bolt and action would work much better. This 700 action works great with most 30 cal magnums, but there are better choices for 300/6.5 PRC.

A: Robert - You got em interested .. and I've done some quick reading. Actually, seems the vast majority of things I find recommend against using a 700 action. They recommend instead actions from Defiance Machine, from GA Precision and H-S Precision, So while the 700 action is tried and true, looks like it may not be the preferred solution to this situation. In fact, I found a couple of articles that specifically recommend against trying to build for this cartridge based on a 700 action, due to problems resulting from feeding from the box magazine. You may well want to do a bit more checking around before you commit to this 'solution'.

A: You could but the short action would be best and have No problem fitting 130-150 grain bullets

A: Juan, you could if you are planning to load longer bullets or load the bullet out farther for more case powder capacity. If not and you plan on shooting factory ammunition, save the weight and go with a Short Action Bolt.

A: Juan, This short action setup will be less engineering in the head spacing of a 6.5 PRC round.----https://www.budsgunshop.com/catalog/product_info.php/products_id/2385/remington+action+700+sa+ss+308

A: 85285 is a stripped receiver "This is a long action receiver for Ultra Mag calibers and is the receiver only with no bolt, trigger group or magazine parts" 85320R comes with a bolt face for a 300 Ultra magnum and a externally adjustable X Mark Pro trigger.

A: Robert, this is a complete Receiver : action is equipped with Remington's new, state-of-the-art, X-Mark Pro trigger for improved trigger pull and easy adjustment. The easy-to-reach, two-position thumb safety has been made more robust, engages quietly to prevent game-spooking, and allows unloading while in the "safe" position. ------------ The other is a stripped Receiver is the receiver only with no bolt, trigger group or magazine parts.
