[QUOTE="AZShooter, post: 2177386, member: 5219"] DJ: I know this is slightly off topic as the OP asked about the 240 Roy..... My friends and I purchased heavy Bartlein 5R 1 in 7.5 twist barrels 30" long over a dozen years ago with the intent of shooting the 115 DTAC bullet. I made a 6mm-284 and one guy made a 6mm SLR, the other made a dasher. None of us could get those bullets to shoot! One friend, the one who recently has a pending world record 1000 yd heavy BR record had the dasher. If he says the bullets wouldn't shoot believe him! link: [URL unfurl="true"]http://bulletin.accurateshooter.com/2021/03/sunday-gunday-300-wsm-pending-1k-world-record-heavy-gun/#:~:text=The%20current%20Williamsport%20HG%201000,2.815%E2%80%B3%20held%20by%20Matthew%20Kline.[/URL] I moved on to 107 Sierra MK and they shot well. Here is what I tried from my document files: I switched to the 107 Sierra matchking. Test results: with RL-17 temp 64 degrees 47 gr 3230 48 gr 3285 showing signs of pressure slight bolt lift -------------------------------------- with H-1000 and Retumbo. Retumbo worked the best of those three powders. 57 gr of Retumbo with 107 SMK was most accurate velocity 3363 ave of 5 shots I repeated the chronographing and shooting for three range sessions and stayed with this powder for a while. ------------------------- tried H4831 with 107 sierra 50 gr 3116 average for 8 rounds -------------------------- RL-22 with 107 SMK 52 gr 3210 52.5 gr 3250 53 gr 3283 most accurate anything past this showed pressure All the above loads with the 107 SMK had the bullet very close to rifling. ------- Then the 105 Berger hybrid came out. Switched and never tried anything else. [/QUOTE]
