Any thoughts on a 338-06 to accomplish the need for both an elk and deer rifle? Would appreciate any insight into comparing, now, the 6.5.PRC, 300 PRC, and a 339-06. Much oblige!

You could get Gunwerks to build it for you. Or you could get a 300 Sherman, which is essentially a 300 PRC AI, or you could get a Remington Long Range in 300 Win Mag which is the PRC's ballistic twin and have it accurized by Gunwerks. The Long Range weighs about 9.5 lbs bare and will shoot within an inch at 100 yards. It can be made to shoot better pretty easily.
Welcome to the group from Az. Sounds like a different thread should be started as to not derail the OPs question.
That being said a 338-06 is not very effective with a 200 grain bullet after 400 yards. With a 200 grain bullet it loses 400 FPS from 100 to 200 yards. Here's a quote below. These bigger bullets need to moving along at longer ranges in order to open up and expand.
"Of three factory loads for the .338-06. One drives a 200 grain Nosler Ballistic Tip bullet (SD .254, BC .414) at a muzzle velocity (MV) of 2750 fps with 3358 ft. lbs. of muzzle energy (ME). At 200 yards the figures are 2364 fps and 2482 ft. lbs.
The other two factory loads use 250 grain bullets (SD .313). These start with a MV of 2500 fps and a ME of 3496 ft. lbs. The more streamlined of the two, a boat-tail spitzer, is still traveling at 2134 fps and carrying 2528 ft. lbs. of energy at 300 yards."

This.The clicker is hard bolt lift and occurs after 4,5 reloads on most brass. It occurs when the brass is not smoothly extracted from the chamber and it pops loose. It happens at the top of the bolt stroke. The reason it happens is the chamber and dies are so close in tolerance that the brass is not resized enough when reloading. Do a search on here and you will find some very detailed threads. This way we won't derail this OPs thread. Here is one below.
The PRC die "problem"
I think my decision between PRC and SM may have just been made ... Worst case scenario is firing actual 300 PRC ammo in the SM ... the SM will allow me to 'download' to lower pressure and get same velocity as the PRC ... but with better brass life and have the tank available for higher if ever...www.longrangehunting.com
Cliff notes version. Some chambers (more like most) or rather the actual SAAMI spec is too tight. Numerous solutions have been tried, smaller dies, etc... The solution is to open up the chamber slightly at the 0.200" line. Reamer print specs are in post #131 of that thread complements Alex Wheeler. It's worth reading the thread but it is long.

That sounds like a sweet setup. How well do they cycle? And don't they use a different bolt face? Dang it. Why did you have to post that lol
I typically talk to myself when in need of expert advice. Apparently, that's not working well for you. Let me be your adult supervision spiritual advisor in all thingys gun related. You can trust me. I am experienced. Buy the 300PRC; keep the 6.5PRC; and, begin planning your following purchase for an even bigger boomer. There, all better. Easy peasy, no queasy. Line forms to the right. Next question.
UH...I think I've spotted the fault in your logic pattern. Refer to post #48. That's why they sell more safes. Tip: you can sell that 1st born to fund more safes. Youngins are almost a limitless resource. May have to upgrade wifeys somewhere around every 12-14 youngins though. For every safe purchased, if buying the proper big uns, one can buy 25-40 more guns. It is a perfect recipe. You are welcome.

Man I hate to say this but I think your headed in wrong direction. The 6.5 is just performing so well for us on elk out to 800. Be honest with yourself on what your capable of and what your gaining or losing. Alot more recoil in the 300 so shot error could be a bigger factor not to mention weight. The 6.5 are nice to pack around all day.

6.5 PRC hands-down. Killed elk at 800+ yards. Got to use Berger bullets. 156 gr. You should be able to get your velocity close to 3200 ft./s. Look at the charts. Nothing comes close in that caliber. It is super sonic to 2400 yards on an average day.
To what end or need is my question? Once you move to 338 you loose the lower grain, faster loads of the 06...110-165 gr...and for heavies of the 338 you don't have the case capacity to make them shine either. Just one man's opinion here. If I jump a caliber or 5 it's because I want a jump. 338-06 in my mind...not ....30-338...yup! 30-378 yuppers!
Enjoy your 6.5 and learn to shoot, develop loads, etc. Not too many elk around that could tell the difference with a well placed shot between the two PRC's. Plan ahead and save for a dream build on the 300 in a year or so. Repeat. Everyone needs a great shooting .308 WIN, so don't get rid of it.

Yes. I do that with a .35 Whelen, which is similar. You can launch a 225 grain .338 bullet from a 338-06 at around 2600 fps in the Nosler manual, and up to 2675 with some of Hodgdens's powders, while exceeding 2750fps with the Sierra 215 grain bullet using BLC(2), which is good enough for elk at 400 to 500 yards, and will stomp a deer within 600 yards. Your brass is easy to make just by passing a 30-06 case through a sizer and trimming the mouth, and bullets up to 300 grains are easily available. The best weight range for this round is the 200 to 250 grain bullet, with top performance in the 215 to 225 grain range. If you get an Ackley Improved .338-06, you can add about 75 fps to all velocities and with some bullet weights, as much a 125 fps. I'd like to have one, but my .35 Whelen does all the .338 will do and a little more. The advantage to the .338-06 is bullet weight and B.C. which is high. The .338 caliber projectiles are like the .284 projectiles and give a high B.C for weight. Get it made with a heavy sporter barrel or light varmint barrel at least 24 inches long, and 26 is better. That adds about 50 to 75 fps to the velocities, and makes it possible to get good results (above 2575fps)from even the 250 grain bullets. That makes it a good bear-moose round, too. Also, barrel life will be high. I've shot around 2500 rounds through my first Whelen and it still holds within 0.7 for 5 shots at 100 yards.
