Probably because the Woodleigh FMJ consistently produces the highest barrel strain numbers across the board for all calibers tested. The Hornady DGS and DGX being right behind it with the second and third highest barrel strain values. Are they safe in your rifle? Only you can make that determination. After all, most manufacturers use the Hornady ammo to regulate with. But, if there is a bullet on the market with arguably better performance (FN vs RN) and Objectively Provable lower stress to your barrels, why not at least explore it. This statement about the Woodleigh only relates to the FMJ. The Woodleigh Soft bullets produced a barrel strain value that pretty much fell right in the middle of the data. The Woodleigh Soft was considered to be the benchmark bullet as being "Safe" for use in doubles. My experience with the CEBs so far is that they are more accurate than the other bullets I've used in the past (had to change powders on one caliber) and I'm actually getting a bit more velocity with the same load.

I haven't shot any game with them yet, but have a pretty aggressive hunting schedule over the next 13 months where I'll be using the CEB BBW#13 Solid and Non-Con exclusively on animals ranging from Black Bear to Cape Buff and a couple of Elephant, (Tuskless and Trophy Bull). So far, all the field reports of the CEBs have been nothing short of a quantum leap in performance.

Jorge, with my Chapuis 9.3X74R, I found that the CEB's were spread a bit more than my previous load with the Barnes Banded Solid. But the velocity was down about 200fps with the same powder charge. Once I brought the charge up (within the listed maximum data) to get the velocity back to 2425fps, the CEB's actually tightened a bit over the Barnes. I ended up having to switch powders however to get the rifle to regulate with the scope on, but this occurred with all bullets tested, not a CEB issue. If I remember correctly from your AR post, you didn't shoot the CEBs over a Chrony? In order to get the most out of them, I think you'll need to get an accurate measure of velocity.

In my 500NE, I found the load I was using with the Barnes bullets to significantly tighten with the CEBs. I also got an increase of about 75fps with the CEBs out of my 24" barrel.

At this point, I totally sold on them. Good luck with your rifle! It's a beaut!!

570gr CEB BBW#13 in my 500NE at 50 yards. The bullets are just touching now. With the Barnes Banded, they were about 2" apart with the same load. 2127 fps avg.

255gr CEB BBW#13 Non-Con 9.3X74R at 50 yards. Two lefts, two rights, with the scope on, no crossing. 2425 fps avg.
