Firearms44 and I did some .35 shooting today. He brought a custom Remington Model Seven with 20" stainless barrel and I brought a Ruger Frontier with a 16.5" barrel. Chronoed the old Winchester 200 grain Silvertip and the new Hornady 200 Spire Point...
Hornady 200:
16.5"... 2352/2357
20"......2361/2449/2445
Winchester 200:
16.5".....2360/2401
20".......2464/2281/2373
We were trying to conserve ammo and just wanted to shoot enough to get a ballpark area what the velocity was since it will shoot differently from different rifles anyway...
From a 22" barrel the Hornady load should be doing about 2525 fps....I'm going guess the Winchester will be about the same.
In checking my reloading data for the Frontier:
51 grains of 748 w/220 Speer FP......2210 @ 80* (2170 @ 50*)
Killed a large doe with this load so even though it is slow it got the job done one could "eat right up to the hole" on both sides.....

.......RJM,,,,,,,,Doing the math by adding up your velocities and then dividing accordingly, the 200 gr Hornadys from your Frontier averaged 64 fps behind the Remy 7 or 18.28 fps less (per inch) of shorter barrel length.
Using the Winchester 200s and going by your #s, the average is surprisingly much closer averaging only an 8 fps total difference between both barrel lengths. Throwing out your low figure of 2281 fps from the 20" barrel, the average reduction then becomes a total of 38 fps or 10.85 fps per inch.
Another two of the same rifles will probably get somewhat different results but nevertheless, here is another example that when shooting the same ammo, reductions of between 15 to 20 fps per inch of shorter barrel length is very true and very realistic.
Vs the longer 24" barrels and shooting the same identical ammo, my Frontier ran 16.4 to 19.5 fps (per inch) behind.
