Anybody try CFE223 in the 7mm08 with 120 or 140 grain bullets? Didn't see any load data given here and was just wondering. Dan.

I have. Good accuracy but slow, much slower than Big Game.

That's what I was wondering about. First results with Big Game has done well. Will tweak it some as time allows. Dan.

I use a magnum primer in my BG loads, seems to tighten my groups a bit.

Hornady brass.
120 pro hunter
42.5 g varget
Fed 210

Shoots well out of my son's savage 110 youth rifle. The 120 ballistic tip and I think its 43 g of varget shoots just as well and has preformed well on whitetail. Image

That groups looks good. Plan on trying some 120 gr as well. Dan.

Tried out the 140 gr Nosler AB with 46 grs Big Game on a doe at 180 yds. Split the heart into and exit wound was about 2 inches. Still ran about 65-70 yds but pouring the blood. Bullet performance was very good. Hope to have a 120 gr bullet load ready to try for next year. Dan.

I've loaded for 7-08's in the following rifles: Sako A-II, Finnlite, Rem Model 7, Nosler 48 Heritage, and most recently a H-S Precision 2000 sporter. All with sporter weight barrels and 140 gr bullets. The two powders that I found worked well were I-4350 and WW 760. Depending on the rifle, 2800 fps was possible with 760. I felt that 760 worked better in cold weather with magnum primers. I'm not listing charges as your chamber and brass will have it's own limits.
Currently shooting RL16 with 140 Accubonds. At magazine COAL it's compressed pretty hard before I could get to 2800, even with a long drop tube. Bought the RL 16 to try in a 6.5 CM.

That's funny. With RL16, I was able to push 140gr E-tips to a 2990fps avg in a 22" barrel. 2850fps was more accurate and that was at 50gr.

Let me correct myself. 47.5/RL26 got me 2830 but that is half way up the neck. I'm shooting 46.0 at 2770 because the precision is better in the H-S there. Your 2990 seems pretty aggressive to me. How many losds do you get on that brass?

What brand of brass? Barrel and COAL? I am using Lapua brass and a long drop tube.

Was that over a Magnetospeed or similar chrono? That’s a hustler of a load.

I would think 50gr is over pressure according to Alliant data.

I've gone all the way to 51.5gr with a magnum primer. I didnt hit pressure indications, I ran out of room in the case for more powder.

RL26? I thought you were talking about RL16. I am talking about RL16. Win brass, 22" barrel, 2.8"oal. Brass has been loaded 3-4 times.

CJ , sorry about taking so long to get back to this thread. I wanted to take the time to diligently research my response and make the post from my computer keyboard to avoid typos from a touch screen..
Yes, I am referring to RL-16, not 26. My mistake.
So, here are some points that I would like to make about your claim of velocity achieved with RL-16 and a 140 grain bullet.
First, I took three brands of 7-08 brass , Lapua, Remington and Nosler, and filled them to overflow out of the top of the neck using a long drop tube funnel. The most that I could get in the case (fired) at overflow is 52.5 gr in the Nosler and 51.4 in the other two. I had tried 47.5 gr in my tests but that was well into the neck and the compression was excessive. According to Quickload, your 50 grain load is 121% fill ratio and yields 86,682 psi where the MAP for the 7-08 is 60,191 psi. .and. that’s for the 140 E-tip. It’s not very likely that you got 50 grains of powder in a 7-08 SAMMI case.
Alliants’ data for the 140 partition states 47.2 gr of RL-16 yields 2952 fps out of a 24” barrel. Running Alliants’ data on Quickload, gives 108%/ 59,534 psi/ 2983 fps. Considering the variables that are specific to the Alliant test platform such as the powder lot and chamber characteristics, I think the Quickload prediction has good fidelity. The Alliant data at 47.2 comes in just under SAMMI MAP for the 7-08.
In my H-S chamber and 22” barrel, I backed off from the 47.5 grains because of pressure indications. I use a blade micrometer on the first firing of new brass to mic the case head for expansion. My 46.0 grains yields ~0’0004-0.0005” expansion, whereas the 47.5 gr load was closer to a full 0.001”. That 0.001” is considered maximum pressure expansion for the case head at full pressure.
Out of all of the 7-08’s that I have had, 2800 fps with the 140 grain bullets seemed to be prudently achievable. The Sako AII was sub-MOA at 2825 fps and that made me happy. However, it took 48 grains of 760 and a 9-1/2M to get there. I used an Oehler 35P for my velocity measurements until recently and have stepped up to the Labradar. My Nosler 48, 24” barrel” was sub-MOA with IMR-4350 and just over 2800 fps.
Looking into the Nosler manual, they are listing velocities of 2922 fps and 2953 fps with RL19 and Big Game respectively. But that is also out of a 26” barrel. IMR-4350 has been such a versatile and strong performer for me in a number of calibers that I bought it in 8 # cans. The same Nosler Manual data shows a case full of IMR-4350 gives the best accuracy for that powder whereas RL-19 and Big Game gave the best accuracy at lower than maximum velocities. Being the old Curmudgeon that I am and resistant to change, I think I’ll stick with my tried and true 760 and IMR-4350 in the 7-08. I do have an 8# jug of H4350 that I will probably test in the H-S to see how that does. My venture into RL-16 was because I had it and it is billed as being temperature tolerant.
wvbuckbuster, earlier in this thread I stated that I don’t like posting my loads because no two rifles will demonstrate the same max chamber pressure for any given bullet powder combination. You seem savvy enough to read between the lines here and take a sensible approach to your loading. In this post I have presented data from traceable sources that pretty much conclude that in a standard 7-08 case with a 140 grain bullet seated at a 2.80” magazine length, 47.2 grains of RL-16 is pretty much the common sense limit. Maybe if you had an Ackley Improved chamber in a long action and a chamber throated to seat the bullets no deeper than the base of the neck, you could use 50 grains of RL-16. Nosler data says that you are probably on the right track with your Big Game testing.

I can assure you that I did in fact put up to 51.5gr of RL16 in a Winchester 7mm-08 case with a 140gr E-tip. In fact, I took a picture while loading them. I would have tried 52gr, but I don't think it would fit. Like I said, 50gr was the most accurate load and it was 2863fps avg. I started with charges that were lower and worked up. Different lots maybe? Just stating my data, your mileage may vary...

I want to thank everyone that shared their loads. I hope I haven't caused feathers to be ruffled . Desertcj I thank you for your confidence in me and I assure you I take great pains to carefully make safe loads. As for me I load and shoot what is the most accurate and doesn't have to be the fastest as long as it is safe. Sure I like for loads to be close to the max listed but not worried if it isn't. Thanks again everyone, Dan.

I meant to say walkinghorseman. I understand not wanting to post an actual load but it comes with understanding that it is safe in your gun and needs to be worked up to. Thanks, Dan.

I recorded 2.155" ogive to base. Best I can tell is that works out to 2.892" oal. I don't currently have any loaded ammo so I had to measure a bullet(140gr E-tip of course).

For sure. It works for 140gr, but I'm of the opinion that it's on the edge of being too slow burning. I think it could be really good with 160gr though...

Most accurate and deadliest on whitetail for me was a max charge of W760 CCI 250 and a Speer 145 gr BTSP. This was out of a Rem 700 CDL 24” barrel. I shot probably a dozen or so deer with that load and they all dropped on the spot or within fifteen feet. Nothing too far, maybe 200 yards. Must be one of those perfect impact speed for the bullet situations. That bullet works well in my 280 on deer.
