Hi Mr. Strohmeyer, The difference between a fast and slow barrel may have something to with age. A fast barrel has been "shot in" using the shoot and clean process in order to get a good "shine" inside the barrel after its initial construction and will settle at aprox x200 rnds A slow barrel is a barrel that HAS NOT has this process and still has engineering burrs in the barrel, which will eventually clear but will take longer without a cleaning regime. If your Remmy is quite new it could explain its lower speeds. Just a thought as is have done this recently on my 243 when i had it re-barrelled ... now pushing Barnes LRX @ 3300 FPS I am also a veteren and liked your kind words at then end 😘 Kind regards, Callum (UK)

Great comparison. Been hammering elk with my .243 for decades using 85 grain Nosler partition at @3250. Of course, shot placement is everything and 300 yards is about the furthest I've taken, but I've never recovered a bullet. Always explodes right through everything and leaves a withering wound channel. The ubiquitous. 243 is a fine round for deer and elk in the right hands.

I use a Magnetospeed Sporter.. Attaches to the barrel for quick set up and is accurate. Easy and clear instruction are included. Thanks for watching.

Barrel length is not all that matters to pick up velocity. At what length dose the powder reach its max pressure? After that the bullet will only slow down. Also the twist rate matters. the more rpm's the bullet turns will reduce the powders ability to produce higher velocity. And if you get really scientific barrel contours combination with length could create negative barrel harmonics that could cause more friction and slow down the bullet. The list goes on and on about things that impact bullet velocity. But I like the video.👍

No, the Weatherby is 1/10 and the Remington is 1/9.25

Other than some sort of QC issue that could be robbing that gun of performance since remington qc is absolutely terrible in the last 20 years, perhaps it's that you're using a faster burning powder where the powder us all burned and maximized in that 20" gun where the 22" will either be the same or even slower since there's friction on the bullet but no more combustion propelling the round faster? Just a thought?

In later videos, I was able to achieve my desired velocities. Thanks for your comment here and for watching.

It would have been interesting to know your powder choice. I would bet that it's a faster burning powder and well-suited for the Vanguard's 20" barrel, but the pressure has started to decrease after 20", signaled by the lower velocities and increased SDs. I know this is a video, but you need more than 1 sample of three shots to be confident in your statistics... a dozen shots per load would be the minimum. I assume you've seen the same relative results several times. Try a slightly slower burning powder in the 700. You know you've gone too slow when you can't get more velocity with a max load.

You ever slug the barrel to see if it’s out of spec and over bored? I cast bullets so I slug most my barrels. My 35 whelen 7600 is .358 and my 7600 35 rem and 336 rem slug at .357. My whelen doesn’t group the greatest and I would assume it’s because it over bore’d. Remington told me it wasn’t out of spec at .358. I would assume the larger bore also has gas cutting, lower pressures, and poor accuracy with the .358 jacketed bullets. Wondering is that's the issue with the slow velocity on yours as well.

Interesting testing procedures that you have done with your rifles. But no I have not slugged a barrel. My primary tests are first to test various bullet and powder combinations for precision ie; velocity/ low SD's/ low ES. Then focus on acceptable point of aim and point of impact that is repeatable. Then calculate trajectory for MPBR. In later videos on this model 700 I was able to obtain good velocity just through a powder change. Thanks for your experience sharing here.
