Planning on buying either a Ruger M77 Hawkeye or a Rem. CDL around spring and eventually will be upgrading to a custom barrel.
I've heard great things about most all of them. Shillen, Krieger, Hart, ect.
In a conversation with one of the other HN members, he mentioned that his Hart custom barrel was "very fast", and I've read how one rifle with a Shillen barrel (just for instance) might not give you as much velocity as the same rifle fitted with a Krieger barrell (again, just for instance).
Has anyone had a significant increase or decrease in crono'd velocity after going from a factory barrell to a custom one? Or going from one brand of custom barrell to another?
most custom barrels are faster that factory tubes, add to it the min spec custom chamber cut in it which doesn't show the normal signs of high pressure, and you get a substantial increase in MV, but button rifled barrels are faster that cut rifled barrels, why I have no idea but they are. The canted lands rifled barrels are said to the fastest because of not as much drag on the bullets.
And at times you just get a fast barrel, or one that will shoot faster without showing pressure signs.
I have a 9 twist lilja on a custom 7mm STW, the load I shoot in it is 4 grains over the max charge for a 140 gr bullet and shoots 200 fps faster than most, and I'm still 2 gr under any pressure signs in my rifle.

I would think that most custom barrels would be as fast if not faster than a factory barrel just from tighter tolerences, but has anyone seen a difference between different custom barrel makers?
I mean, does one brand of custom barrell seem to always be a little faster than another brand?

Yeah it seems the Broughton 5c has been showing quicker then normal speeds...

I have had Shilen, Pac Nor, Apex, Benchmark, and Krieger. None were fast. I am not a huge believer in fast barrels, I just think sometimes guys can load to higher pressure without seeing any pressure signs.
I guess there is one exception. If the groove dimater is say ..0005", then the barrel might be fast.
As a benchrest shooter for 30+ years and owner of many many barrels I can tell you that there is some truth in velocity changes between barrels, to be honest about it not much but I've seen the same loads shoot as much as 50 fps difference with all things being equal.. the new gain twist barrels I've yet to mess much with but they seem to show some gain listening to the shooter on the line.. in the hunting world it not even worth talking about such slight differences to be honest about it.. a lung or heart won't tell the difference between hits with 50fps difference... barrels today are for the most part outstanding... Krieger, Bartlien and Broughton seem to be the honest going the competition circuit these days.. but they are all great.. who does the chamber work and the tolerances of the reamer seem to affect and have an effect more so than the barrel manufacturer.. a chamber cut with a reamer that has been worn slightly will really tighten up the chamber and you'll see some major velocity increases..EITHER way just make sure you break it in correctly, clean it and it'll last forever on a hunting rifle..especially a big game rifle..how many shots do we actually shoot at game anyway.
Custom barrels...some "faster" than others?
