Now that I'm back in New Zealand, I just picked up a new barrel conversion I had my local smith working on. It's a 36" Bartlein 5-R progressive twist 1-10/9 chambered for .338 LM Improved with a JDJ reamer.
I've been frustrated in the past couple of years here at ELR matches where I clean targets out to 1400m then get bested at 1600 and 2000 by guys with 32" barrels shooting 300s. My 26" barrel shoots 250s nicely but not 285s and is really picky with 300s and there's no way to match their velocity.
So this barrel started as a 37" non-tapered blank and is heavy as it looks. I'm not going to flute it just yet but I might contour it a bit more to bring the weight down. The goal with the improved chamber and barrel length is to push 300s at 3100+ fps which should stay supersonic to nearly 2100m.
