338 PRC magnum length would get me excited...
ideally 340 performance, no free bore,

not sure what a .338 PRC would produce...

I wish I could shoulder a 340 weatherby. I friend of mine wants me to tune a 300-378. He’s twice my size and when I brought up the fact that I suck with heavy recoil he says he tried a couple different muzzle brakes and the factory muzzle brake worked the best, barely has any kick. I still have my doubts. He paid a reputable guy for load work up with 210’s and turret info so I’m guessing it’s a freaking beast. One thing I’ll add while I’m rambling that I have noticed with the factory 300 weatherby ammo is that for long range hunting, I would do some cold bore shootings at different temps. The 257 and 6.5-300 seem almost immune

Update on things if anybody’s interested. Finally got out to chrono the weatherby. Got some brass fireformed for the prc

Interested in how the Weatherby stacks up with the PRC.
What did the Weatherby do with the chronograph?

Well, I found a good accuracy node at 77.2 and 77.4 -rl25 so I split and loaded 30 rds at 77.3, I annealed 15 and left 15 at 2nd firing. Both batches averaged 2654 which was about 100fps slower than Hornady data would have them with 24” barrel. I’m shooting about 600’ elevation so that might be the issue - not sure. Still, laser beams as far as accuracy goes which still makes it plenty good for some long range fun. I’ve decided to go with the 245 Berger’s in the prc since it will be used to hunt. I loaded up 40 @ .2 ladder with 212 Hornady and ramshot LRT mainly to fireform but also out of curiosity. Powder is way too slow, last 4 of the string were starting to compress and had a long ways to go to reach max. Horrible shooting on my part trying to get used to this gun, not that I was planning on using but I’m glad I used the cheaper bullets to start. I’m pretty sure I figured it out on the last string but good grief. To make matters worse there was an old timer there blasting 1/2 groups with a 338 RUM lol. What a blast though, I had my Creedmoor set up on another bench and was smacking this 6” blob of steel they have hanging off the 500 meter rail ( got a competition on the 28th). I’ll see how the leupold tracks with the leupold data in a couple weeks and start load work with the Berger’s. Might see if my brother wants to use the weatherby in the hunter class at 600, it might be hard to beat but he’s got a pretty good chance with his 6.5-284 Norma so hard to say. Anyways, sorry so long. It felt so dang good to get a range day with all the crap going on

Finally got out to see how the weatherby would tracity. Spot on out to 400 meters but something’s wrong at 500. Going to have to set up a target camera and shoot some paper to see. Think it was user error with the ballistic app. Got a new kesler that probably had the correct moa but was short on time. The 300 prc was giving me fits. Finally figured out the screws holding the rail came loose. Blue loctite this time gave me some decent groups. I just left the chronograph strapped to the barrel while I shot hoping to kill two birds. Long ways to go but last group was around an inch at 200 and 2650 with the 245 Berger’s. Got two hot to keep shooting so hopefully next weekend I can figure out the weatherby and continue with the prc. Hope they don’t shut us down from going to the east side for our long range plinking party. Sure be glad when this virus is history

I have a fibermark 340 no brake, I swear it kicks less than my 300win.mag, but that has a wood stock and a muzzle brake! browning,

it's slightly less IMO.

it definitely let's you know it went off.
I think a synthetic stock, with a good brake....could mellow a 340...but I'm not a brake fan.
I am thinking about a .300wsm in a lighter magnum setup...with a bit less kick. kind of a do all modern 30.06.... I think 300wsm w/ 150gr TSX.... if I need more gun, the 340 w/225gr TSX will get the nod.

If you can shoulder a 300wby, you definitely can shoot a 340wby. for what it's worth.

Lol, this ones a beautiful vanguard with a wood stock. Anniversary edition. It’s the most accurate gun I’ve ever shot with factory 180’s. It’s my brothers and it was probably going to be a safe queen. The president of our gun club built and installed a muzzle break on it but it still leaves my shoulder black and blue. I started putting a stocking hat between. It’s a challenge to see if the 500M gong is swinging after a shot lol. I could probably squeeze quite a bit more fps out of it but I’d have to have someone else shoot it. My brother shoots heavy recoil better than me so it will be fun once they’re both ready.

Did your gunsmith thread the barrel and install the brake?
Sounds like you need a different one that cuts more recoil. Not saying anything against your gunsmith but they make brakes that can cut recoil to almost zero. That may help you at the bench

Ya, I hate to mess with it. The brake is one he designed for competitions that generally are smaller calibers. It’s freaky accurate with 180 factory ammo and it’s punching a silver dollar hole at 200 now with the 208 Hornady’s so just need a stocking hat to eliminate the bruise lol.
