Without going into details, for a hunting rig, will a 1:12 twist be ok for a larger 30 cal.
300 win mag for example.
Not worried about gongs at 1000 yards, 200grainers (probably less maybe 180s max) for a LR hunting set up 500yds tops.
factory ammo only
Thoughts?
1:10 would be better
As mentioned 10 would be much better.Quote:

200gr probably a bit heavy.
I had a TrueFlite 12 twist barrel that stabilized 185 Berger Juggernauts against everything the twist theory calculation said...
The Juggernauts are a rounder, fat projectile than the Hybrids, so projectile shape probably has something to do with it as well...
yup that sounds pretty much what my internet research is coming up with. length of bullet etc can come into it as well
1:10 the best all round. TBH hunting loads only so 180s tops really.
anyone tried it for real though?

If I get another 300WM it will need to shoot the new 200+gr projectiles.... because they look cool.
I've never done anything for real Cam its all just fluff on the interweb :DQuote:

Plenty enough for +700m
1-12" twist is marginal for accuracy (borderline stable) for most high BC 180gr range projectiles. A true 1-11" or faster would be a better choice. I have a 1-12" twist Kreiger sitting idle because of this :XD:
Wasnt quite meant that way lol. More for about the hunting part.Quote:

I suppose it isnt worth having a 300 mag if you cant nudge 200 plus grainers one day.
did I say its really cheap?
Hence my inner pack rat trying anyway I can to justify getting it for later projects.
FAAAAAAAAA That's some serious muzzle energy right there. The new projectiles have seriously good BC Numbers so it's not wasted.Quote:

Get it then and have a play. You could try to wear some 110 grain projectiles off in the rifling :thumbsup:Quote:

I am going to see if its still available this morning.
If it is indeed as cheap as I believe then it would still be ok for a 308 anyway.
If my 303 project shoots crap that was what it was pencilled in for.
Fires out-nothing to see here.
Major cockup-barrel didn't exist, mixed with wrong listing, wrong price etc.
If they say it is too good to be true it probably is. Never mind.
Another fail, took the verniers in to measure possible other donor barrels as my BSA p14 project will one day turn into something else.
These are a bugger as they are bigger diameter than normal.
Only barrel that would probably work was an almost new (maybe spare part) Springfield '03 30 cal. barrel with the most hideous rear sight/knox you could imagine. The square threads gave it away and they still wanted silly money for it.
The search goes on
