How far off the grooves do you set the 230s? I have the ones with the higher bc .743 the hybrid target bullets.
With the 230 OTM , I'm seating mag length (3.620") which means I'm jumping well over 100/1000's. I also shoot the 230 Hybrid targets. Talk about LONG. 3.011" to the ogive and I think it's in the neighborhood of 3.725 coal. But the hybrid targets WILL NOT SHOOT in my rifle unless they are snugged up against the lands. The hybrid targets shoot very well.... Just have to single feed.

Thanks for the info. I did set them to the grooves (which was a guess about where they would be happy) but it was my first time out with the new barrel so I didn't have a lot of ammo to shoot groups. I did have two touching but I pulled the last one. I don't mind single feeding I shoot less. I appreciate the help anytime I can repay let me know.
Once you moly, you really can't go back to shooting regular bullets ?? Never shot mollified bullets but if they would preserve bbl life I would be interested
You can also look into HBN/BN (boron nitrate). It's supposed to be slicker and not have the buildup/hardening effect moly has. It's definitely cleaner(as far as the coating itself)....

I've never tried to go to naked bullets after moly so I can't say for sure I couldn't do it.
My last barrel went past 3000 rnds running moly, & this one is @ 2750+ so far, & is still accurate. My cleaning regime is to run my bore snake through a few times after each use, & a full cleaning every year or so. I don't expect to get 8000 rnds through a barrel, but I don't see why 5000 rnds isn't possible.

Yes. I use the moly oil after my yearly cleaning and it only takes a few rnds to foul back to normal.
I just took my new 26" shilen barrel out yesterday to start load work using the 208 amax and reloder 22... My hopes with this rifle is to reach 1800+ yards with sub moa accuracy. after shooting some charges through the chrony these are my results with this combo: 208 amax, Hornady case, rl22, fed215, seated -.015"
67gn= 2825 fps
(mild)
68gn= 2859 fps
(no pressure signs)
69gn= 2916 fps *possible node
(primer flattening, no other signs)
69.5gn= 2919 fps
(flatter edges of primer getting warm)
70 gn= 2957 fps
(ever flatter edges, getting warmer)
70.5 gn= 2988 fps *possible node
(completely flat primer, slight cratering, slight ejector mark, easy bolt lift)
I like the velocity of the 70.5 charge but my concern is overpressure especially after bedding a manners t5a stock to my action. my next step is to do a 500 yard ladder after sorting through bullets base to ogive...

That seems like a safe dependable load. That's very good speed for that charge weight too !
I'm taking the 215's out to 1470 yards tomorrow. Also the 230 OTM's. shot at 890 yesterday and it should be roughly 12.2 mils with the 215 and 13.6 to 13.7 with the 230 OTM to hit at 1470. Will report back tomorrow and let you guys know my results. Not sure how to post video but it'll be filmed.
Well we are working on the 1470 range right now. Have to get pallets to raise the AR500 steel plate due to the topography. But I did hit at 1330 yards center mass. 10.1 mils to get there with a 100 yard zero. Will report back a little later.
I'm at 4400' asl which helps a bit with mv... going out soon to test at 1000 yards with this load. Lately I've been practicing on tightening up my fundamentals with my 308 shooting prone off of concrete mostly 100 yards breaking position and reestablishing for every shot. This REALLY has been helping me get on target every time i get behind the rifle. I've been shooting for about a year now and really need to practice good habits. wish i had watched the rifles only video from the get go wouldn't have wasted so much ammo. but u live u learn right?
Well, 1470 was not achieved THIS time. Trigger Time TV was filming and had alot of other things they wanted to do. So basically my buddy and I shot at 1330 while they were fimling some things on another one of our ranges. He shot a 6 Creedmor with a 105 hybrid and I shot the 215 hybrids. That SOB shot 4" group. I had 3 go down range with only 2 hits. But the mirage was so bad you could barely make out the target much less the circles painted. So, I DO now have it set up to shoot to 1500... But it's going to be off my tool box , resting on the top of the hood, which is fine with me. The 215's impacted hard, the 105's.... Ya know... Not so much. Also learned that I need to be shooting at sunrise or sunset... Even at 15 X out a 4.5x30 XRS the mirage was still terrible. But given the conditions which we were shooting in and the lack of shooting this particular load past 1,000 I was very pleased. My buddy was tickled shitless.
