I’ve read some about this gun/action. Kinda interesting. Eyeballed one at a sporting goods store and it looked pretty good.
 
 
Got mine sighted in today!! It's in 300 wby, action was smooth, so far it's looking like a good one.
it's a Remington 700 clone and advertised on Weatherby's site as being compatible with 700 parts/ upgrades. Roy is rolling in his grave. The final insult is the Chinese vortex scope. Congratulations.
 
Ya I thought I would try a vortex out. Budget scope that seems to work great. My vx 5 was almost 2k i got this spring. This Chinese vortex was reasonably priced.

Doesn't the Mark V accommodate Remington 700 scope bases?

Wonder if roys rolling seeing weatherby double radii, and obssession for speed tossed too? Their new designs are different, and better in my opinion.

I bet he's fine and not rolling at all with his family changing/expanding the business and expanding products. They seem like nice people bringing good products to the market.

Someday im going to get an accumark in 300 prc :)

Yeah, he's probably ok with his family trying to keep the brand relevant for customers beyond those buying a name based on what it was decades ago.
 
Here’s another question.

I understand that Weatherby is historically a bit looser on the free bore in their rifles (caution for overpressure?). Is this also the case on non-weatherby chamberings in their 307 and Vanguard product lines? It would seem to be the opposite of the PRC thought process. Or am I totally wrong because I’ve been watching the wrong YouTube videos?

Thanks.

The Weatherby cartridges are Saami spec'd to have that free bore, I believe Weatherby chambers non-Weatherby cartridges to Saami for that cartridge with whatever its normal spec would be.

Ah….makes sense. Thanks
 
PRC cartridges have pretty long freebore from SAAMI to match the heavy bullets they are designed around as well. Not as much as some weatherby mag designs but they aren’t short throats by any means.

Thanks. I’m still learnin’.

Common custom rifle chambering methodology for a while has been to create enough freebore such that desired bullets can be seated with the end of the bearing surface slightly in front of the case neck/shoulder junction and be close to making contact with the lands. The saami creedmoor and PRC cartridges are generally designed around doing this with their heavy for caliber ELD bullets.

The other benefit to longer freebore is that there is more volume behind the bullet when it meets resistance from the lands for the burning powder which reduces pressure. In turn it allows more powder to be burned at a given pressure than a shorter freebore and more powder at a given pressure = more velocity. In the case of many weatherby cartridges, the long freebore is well beyond what is needed for heavy bullets to be seated appropriately and really just serves as a way to get more velocity out of a given case size without excessive pressure. In many cases this means the bullets are jumping a long way to the lands.

Does the longer jump to the lands yield a decrease in accuracy? Or is there no effect at all? Thanks
