Nosler Custom Comp and RDF

I have some 6.5 140gn RDF's on order because I'm getting a little peeved at the unreliable supply of Bergers here in Australia. I here some great things about the RDF bullets but then someone tells me there's nothing wrong with the Custom Comp in 6.5, which are cheaper. I shoot 500m benchrest, so the bullets need to be good in the breeze. The High BC of the RDF is attractive for that reason. Any feedback is welcome. I'm shooting a Savage 12 LRP with a Vortex Golden Eagle.

Lofty; I can't help ya at this point, I was checking to see if anyone with experience with these had anything to say.
 I'll check back in.

I use the 140 rdf's  in my comp PRS gun and find them excellent but I'm not shooting bench rest.

I could not get the Custom Comps to shoot for me. The RDFs were middle of the road, a good value if value shooting is a goal. But, I have talked to folks who worked on the RDFs and got where they want to be.

The 6mm 107 CC's are very accurate in my 6 x 47 Lapua. I bought 1500 of them on sale at Sportsmans Warehouse for 15 cents each about a year ago.

I've never tried the 6.5s

I tried the 130 RDF in my 6.5 CM and they just wouldn't group for me.  They were also very long to get to the lands, so mag length was an issue.  I use the 123 CC all the time in my 6.5 Grendel and it loves them.  The dimensions of the 123 CC are almost perfect for the Grendel.  I would not put them up against the Bergers for benchrest work though.

If constrained by a magazine, you'll find the 140 RDF's tend to
shoot good with long jumps. My last test batch was jumped at
.045 in my 24", 8 twist, Criterion. Plan to move back to .055 for
the next batch.....In my barrel the 140 RDF's did not fare well at
.020 off the lands, The further in the case, the tighter the groups
with WLR primers and 42 grs of R-16.

Lofty, I've used both in 6.5cm RAP and SAV 10 GRS.
Both provided good results up to 400 yards, but the quality of the RDF seemed slightly better.
Took more effort to find a good node with the RDFs, probably all me.
Would still be using the RDFs, but got hooked on 140 ELD-M, just hard to brake that habit.

I tried the 140 Custom Comp in my 6.5 CM at magazine length and only had OK results (0.7 MOA). I needed to get closer to the lands for the CC’s. I was also testing Hornady 140 ELD-M and had better luck getting 0.4 MOA so I use te ELDM at magazine length.

I am getting about 0.85-0.90" with maximum mag length Nosler 140 CC's in my RAP with H4350.  Much the same with that bullet in a 1:8, Hart 29" Palma  barrel that I have replaced with a 1:8 twist Bartlein at 30".  Yesterday I had a 0.612" 5 shot group with the 11th-15th shots down the new barrel with the Nosler 140 RDF and 41.6 gr. of H4350, jumped 0.035".  I have also had several sub 0.5" groups with the 6mm , 105 gr RDF in my 6BR-Norma rifle.  If you try either type of Nosler match bullets you may like what you get, but every rifle will tell you what it likes.  Sure makes it interesting.

I have never tried the RDF bullets. In my 26" howa I'm having good luck with the 140 CC bullets though. My load is Peterson srp brass, 40.5 grains RL16, 140 cc at .010" off the lands. The worst this load ever does is in the high .5" range, with the vast majority being sub 1/2" . I've had many groups in the .2-.3 range. The farthest I have to shoot is 512 yards, but they do exceptionally well there.

At 500m, I don’t think the difference in BC will make that much of an impact. I started off with the CC’ as I got them real cheap at the time; they did well in my Howa 24” barrel often giving me 0.5MOA, 0.02” off the lands. I did go over to eld-m though, purely because I was itching to take the rifle past 1600m where the difference in BC made up for lack of elevation adjustment in my rig. Interestingly the difference at that range was around 11MOA. I never tried the RDF, but again at 500m I don’t think it’s such a big deal using the CCs, especially because they are a lot cheaper.

Just my own personal experience, I guess each rig is different.

I shoot both the 140g CC and RDF and get a little better performance with the RDF out at 1000 yards but the CC bullets are a very close second. Having a longer jump is helpful.
