My measurements are showing these with less jump than the Nosler 125 Ballistic Tip (still a big jump, but less!) and still able to load down to 2.285" before getting into to bullet ogive with a 1.620" trim on the brass. Has anyone played with these yet? They're next on my development list, still thinking RL7 and remington 7-1/2's. Open to suggestion.

I tried to load these and they were to long to load in an ar platform. Seated way to deep to be workable.

ASC magazines let you load out to almost 2.314 or so. They are a good deal at the price.I buy the 6.5 Grendels for my A-30. Never load short on this case if you have magzine space as long as you are out of the lands like the 110's will do.

Madcat, are you sure those were the 125gr SST (p/n # 3019)? If so, there must have been a re-design and I'm not sure if I have new or old. The ones I have almost seem made for the AM30. My ASC mags will only let me load out just a little past 2.300. 2.305" usually rubs but at either of these lengths these bullets extend just barely below the neck into the case and the case mouth is still on the flats of the bullet. In my tube they're hitting the lands at 2.420"

Problem I had with them is the ogive was below the case rim by quite a bit. It has a long cone on it for a good fit in the 300 BO.

Hmmm... I'm wondering if there hasn't been a redesign on them, I'm still measuring full bullet diameter seated down to 2.285" so very much on the flats at 2.300". I've had these on the bench just a little over a year so I'm really hoping if there was a redesign that these are the latest. My local guy doesn't stock them but if they shoot well I'll order another box to find out.

Hornady 3019 is the ones I had. They were flat based. I'll get one from the buddy I sold them too and recheck. Maybe I missed something.

Definitely let me know, I would hate to have the perfect load worked up only to find out they had made a minute change to the bullet that made it no longer workable. As it is I have only a .015" margin in load length to play with to be able to load the bullet at mag length without being into the ogive. I'm pretty sure you bought yours after I had mine already so yours would probably be the newer spec if there is a differencce.

I was going over some of my numbers and I may be wrong about this bullet. I will have one this weekend to make a dummy round with and see. Not sure what I was thinking, it should work fine. I do remember them having a really long plastic tip but still should work.

I loaded them and made it out to shoot today, sadly, the results with this run were less than stellar. They did load well however, bullets seated not much deeper then the neck and case mouth still well on the flats of the bullet away from the ogive. I loaded them at mag length, which in my barrel equals a .120" jump to the lands, RL7, charges in 0.3gr increases from 28.4 up to 29.6 which is where I stopped after starting to see mild pressure signs, these charges were all over a remington 7-1/2 primer. Slowest velocities were around 2485 at the muzzle, highest were 2595ish. I havent measured the groups for exact numbers but everything was around 1.5 mo @ 100.
I'm not giving up on this bullet completely but I'm going to explore some others before I come back to this one with a differnt powder and/or primer combination.
Let me know if you try it and get different results, I would really like one of the hunting-class bullets to work well with this rifle.

Prohunters and nosler b/t work very well

I had, what I would call "limited success" with the nosler b-tips, but that wasn't a fair evaluation since I was still doing barrel break-in. I plan to revisit them soon and I also have pro hunters so I'll give those a spin also.
I'm still struggling with function on this build even after verifying a gas port size of near .090" and running a newly-installed BTE adjustable gas block wide-open. Even loads that are starting to show pressure are short-stroking and everything on the bolt and carrier looks solid. I'm going to tag in another 6.8 bolt and carrier to see if that clears up the problem

I loaded a dummy round with a SST and it will work fine. The cannular is well below the rim so theres a lot of bullet in the case but ought to be a winner with 29 grs of RL 7. I wish I knew why I thought these wouldn't work. I do know the 150gr take up about a third of the case .

I played with several 150gr bullets and found the same. I thought it might be nice to have a slightly heavier slug for certain types of hunting, but after seeing how much it limits capacity, I'm just going to stay with the 125ish bullets. The exception to the above was a 150gr sierra pro-hunter 30-30 flat point, not my first choice in a bullet design but if you wanted something a little slower and less-expansive, this might deserve a look. I doubt I'll play with it any further, I just had a few on hand so I took the measurements and noticed it didn't fill the case quite as bad, in my rifle it hits the lands at 2.290", I have no idea how this style bullet would or wouldn't feed.

It should feed OK IMHO. I've been shooting the standard 150 Pro Hunters and the Hornady Interlocks. Greg
