Re-bore Questions: 30-06 to 338-06

[luke moffat]

I use 210 sciroccos in mine at roughly 2800 fps out of my 21" barrel 338-06. Haven't used it on a tremendous amount of animals but so far it seems to have done well on a caribou, moose, and grizzly bear.

Off to resight it in today.

Now I know this question isn't really the point of this thread, but I have to ask the question that keeps popping up in my head every time I think this project over. Is the 338-06 worth reboring a perfectly good 30-06? For me it would be on a rifle used walking about primarily inside 150 yards on pigs year around.

In your situation I'd put it squarely in the "I'd just like to have one" list - In terms of practical trajectories I don't think you'd handicap yourself nor would there be much difference in recoil, I'd think that when a 210 Scirocco hits a pig at 150 +/- there would be a pretty distinct difference though, that's based on what I've seen a well placed 338 bullet do to elk

I think part of my problem is extreme copper fouling. I just checked the barrel again and it is painted with copper. I will try the 200 grain Hornady SST bullets after I get all this copper out. New barrel may need some smoothing out.

I've got a .338-06 AI project, it's a Marlin XL-7 that I bought a short chambered barrel and head spaced with a finish reamer, I started with 225gr Barnes and had similar groups, think I got it up around 2700 before I started getting nervous about flattened primers.

If I remember I dropped to 210 and was getting better results. I had some low quality brass and ended up wearing out the brass pretty fast and since I sized up some 30-06 and fire formed, I just never got around to starting that whole process again. When I work on it again I'm going to focus on the 210's. That is one fun gun!

what bullet did you shoot initially ? it's cut rifling which is known as a smooth bore generally and not needing much in the way of "break in", you might ask Jess but I think he laps his bores at least a bit - there's been a ton of threads and chatter on Rokslide with many posts by experienced snipers and target shooter as well as hunters who have been saying lately that we all tend to way overclean our bores - I've read and watched one interview by military sniper who stated that it's not uncommon to shoot a barrel "out" before fouling even begins to become an issue - it's your rifle but Jess told me to just shoot it when I picked up my rebored 338 Win Mag, he should know ....
