** I’m just working off your statement here, no disrespect intended**He did try different bullets and powder.
IMHO, those rifles with "pencil" barrels aren't intended for shots past 200 meters.
They're for light, stalking rifles, where shots seldom exceed 100 meters.
Every Rem 700 and Rem mod 7 rifle I've kept for my personal use that had factory pencil barrels on them, I usually replaced the barrels with heavier barrels.
After three shots, groups tend to open up more with every shot.
Some of them, with pencil barrels, shoot very well, but it's luck of the draw.
A youth rifle shooting into 1.25 inches with factory ammo, is usually about as good as it gets. IMHO.
OP, with that twist rate, I would stick to flat base bullets, with short ogives.
Cup and core types, loaded at those velocities, will shoot fine, are cheaper, and at those velocities will perform just as well.
I must’ve lucked out then…
I had my choice of either .270 or ‘06 when I bought my 700 Mtn about a doz or more yrs ago. 30-06 got the nod. I literally just grabbed a box of Barnes 168gr TTSX cause they were a middle of the road choice and have run them since. Consistent 3 shot 1” groups in a nice easy paced fashion. While I could tighten that w/reloads, I don’t feel the need at this point (mostly due to time).
The VG2 in .300Wby I had with their #2 barrel on it, same procedure as above, easily 1” groups with 200gr ELDXs.
I’m hoping (but figuring) the recent M77 UL in .270W will be as comparable to the above two.
Point being… with Pencil or #1/2 barrels regardless of Caliber/Cartridge, you gotta slow down a little. Your groups will get better. Reality is if your firing off quick & multiple shots in the field or at the bench with a bolt action your just spray’n & pray’n. Might be time to consider a semi of some sort
