Re: Rebarreling a savage 110fcp 338 lapua
If the Shilen barrel beats the accuracy of my friend's FCP with the factory barrel, it would be filling a tall order... Savage has really outdone themselves with these 338LM barrels... cold clean bore shots right in the group... accuracy holding up for long strings of fire... my 110BA does the same; a very good shooter.
They do tend to need 50 rounds of break in, on average.
We're shooting 300 grain Matchkings and 89.3 grains of Retumbo in Lapua cases. The 250's in the Savages don't do as well, due to the 9 twist...
If you've been shooting 250's, and don't want to shoot heavier than that, then yes, I'd say you can improve on the accuracy with a custom barrel with maybe a 10 twist for the 250's.
They recently pitted Steyr's best 338LM against the Savage FCP in long range rifle magazine... they didn't shoot anything heavier than the 250's, and there was hardly any accuracy difference between the two rifles. Had they given the Savage the 300's it loves the 6000 dollar Steyr would have certainly lost the contest. ;)
