225 ELD-M in a 1:10 ?

30" 10 twist .300 Win Mag PAC Nor prefit barrel, shooting the 225gr ELD-M's it is probably one of the most accurate barrels I've shot. 74.5gr H1000 gave me 2910 fps and 1/4 MOA accuracy. It was good enough I managed to hit a clay pigeon at 1030 yards so it should definitely work for you.
 
Used a 225 eld m out of a 10 twist .300
Win mag savage 111 long range hunter this very morning to hammer a medium sized buck at around 350 yards. 1100 feet above sea level, winter in Saskatchewan (well below 0 degrees). Dead on accurate, no stability concerns whatsoever. At higher elevation with a hotter cartridge in warmer weather it's a guarantee for you.

my load is the first load I've consistently shot one hole groups with. 225 eld hbn coated, loaded out to single feed, 79 grains imr8133 and fed 215m, ww super brass. 2760 FPS. Perfect performing.
 
I know this is an older post, but thought id re-ask this question, see if anything has changed now that people have had a lot longer to play with this bullet.

It seems like 1:10 works for this bullet, which i always found a bit surprising (not shocking, just noteworthy) as long as that bullet is, but theres too much empirical evidence to show that its ok.

But what is the IDEAL twist for this bullet? If you have a custom blank made (bartlein in my case), for target velocity of say 2600 - 2700 fps (30-06 ackley improved, 30" barrel, single loading, so can run COAL as long as dedired... magwell blocked off). Mostly just target shooting for fun, 600 to 1000 yards, around 1000' ASL. Temp ranges from 20 deg F to 100F. LOTS of wind. 20 mph + not unusual. (Shooting in the wind, i shoot like ****, but learn a lot, only way to get better is to go do it)

So the above is the shooting i am doing now, but i like the idea of versatility, so that if i went somewhere else my combo would work well. Like if i had the chance to go out to 1500 yards or a mile with a place you could spot misses (bc i know id have a lot at that range). Not planning on competing, just shoot for fun.

Anyways, given all the above, would it make more sense to order a blank in the 1:9 range, maybe 1:8.5 even, give a little more twist just for security / reliability? Id really like to run the 225 ELD-M, it looks like the best bullet in terms of performance / availability / cost etc. (Now i know that setting up a rifle to run just one bullet is a risk, bc it just might not work with your exact individual rifle/barrel... but im wiling to take that risk, + there are other bullets i could run too... part of why im considering a faster twist, in case i needed to swap to competitor bullet in similar weight / BC range)

One thing ive thought of is that with cut rifling in general and bartlein in particular, i shouldnt have to worry too much about twist rate being off spec / wide tolerance range. A 1:10 from them should be real close to 10.0... not worried about receiving one thats actually 10.5 or worse 10.8 or something. I could see the 225 ELDM being sensitive to sloppy tolerances on rifling twist... i know i hear of different rifling methods (and -some- barrel makers) being a lot more "open minded" about actual twist rates.

Anyways, blah blah blah. Ill end this book now. Just curious on what y-alls thoughts are :)
