Just the fact that you admit that your bolt lift is somewhat heavy indicates that you'r preassurelevels are high.
 
But we can stop the discussion here, it will not lead any further anyway.

+ 4000 fps with a 204 are pretty common, yet the barrel like is a least 2x in mine (so far) compared to a 22-25- 40 gr around 3900 fps.

Dale a 22-250 will shoot well above 4000fps with a 40gr.......mine is right at 3950fps with 50 grainers. I see 4100fps for 40grainers in the latest lawyer friendly nosler loading book with a 24" barrel!

ya thats for sure especially with 1x14 in twist and 26 in barrel, but it won't last as long as 204 at 4300.

Yeah, I'm glad I've never made any of my cartridge choices based on how many rounds of barrel life I would or wouldn't get.....

I say, shoot em' till the accuracy drops off and rebarrel if you liked the chambering and if not move on......or simply cut it back a little and rechamber it to get a new throat, mostly its the throat not the rifling that goes first. I already have a spare barrel sitting ready for my 22-250 when it starts to loose that quilt edged accuracy. I like to load real warm if I can get the accuracy and never expect them to last forever. I may run a middlestead reamer in the original barrel and use the back-up barrel for 22-250. I view a throat going as the start of a new adventure with my guns.

when the barrel on my 788 goes i think i will have it rebarreled, i like the accuracy of it now out of a factory tube, cant imagine what would happen with a high quality barrel being slapped on there

My tikka t3 has a 24.375" barrel and it is a .300 win mag.  Is that enough barrel for the .300 mag?  How do you know if you are getting everything out of your caliber if you don't have chrono equipment?

you dont but usually the people that make these gun say so, like  the .264 win mag is best suited for a barrel at least 26" long to get full potential

sight your gun at 100 yds, shoot a group at 200 yds, give me the inches differences and I'll tell you the velocity (or tell you how to do it if you want.)

I'd like to know how to get it from that.  I'll have to get back to you on the groups.  I can tell you that I'm sighted in 2" high at 100 yards and I'm dead on at 300.

Drake, 24" is plenty of length to get the most out of the .300 Win Mag -- within reason.  While it may benefit from an extra inch or two velocity-wise, depending on which powder is chosen, at some point, you have to evaluate whether the very slight velocity gain is worth the tradeoff of having a slightly less "handy" rifle.  Also, as you increase length within a given diameter, you have to correspondingly increase diameter to keep the barrel from being too "whippy."  I personally wouldn't want a barrel any longer than 24" on ANY standard hunting rifle.  One of the advantages of the short mags is that they don't require quite as long a barrel as the standard length mags to get similar velocities because of the more efficient combustion the case length : diameter ratio offers and the slightly faster burning powders used.

On a magnum class or even slightly "overbore capacity" chambering, I agree with that to the extent that I want at least 22" for the non-magnums and 24" for the magnums, though I really don't like barrels over 24" for anything I plan to carry much.  For the short mags, 22 - 23" is plenty long enough for me.  For short action, .308 based chamberings, I like 20 - 22" barrels, as that is plenty of length to get the most out of those cartridges.  I don't like barrels less than 20", except on stuff like rimfires, bolt action pistols, and maybe lever action carbines.
