6.5-300 Load Help

[edgecrum]

Cacsrx1... What are you seeing terminal performance wise on the Eldx. Many pass through? Functioning more like a Berger?

[cacsrx1]

Pass through on antelope, no pass through on large white tails(270 lbs). Heart and lungs look like we’re ran through a blender.  105 to 638 yds.

My previous loads that were sub MOA, including factory LRX no longer are. I'm not, at this point, happy with my purchase. I'll be calling Weatherby back this week. I wish so much I had opted for another 257 or a browning hells canyon 28 nosler.

Spoke to a very knowledgeable guy at Weatherby today. Unfortunately a while back they weren't meeting accuracy requirements at an acceptable level so they changed from a 5 groove to a 4 groove barrell setup. Fixed their accuracy problems but hurt velocity in the neighborhood of around 100 fps. So apparently I basically have a 26 Nosler.

Now this is interesting.Who did you talk to? Maybe someone from Weatherby will tell us about this issue and changes made?

Hope you keep us posted on this, l am really  curious about what would all of a sudden make a rifle not shoot a load it  previously was. Without some  altercation done to the rifle, bedding, changing the pressure point if it has one etc.
You must be a very  experienced reloaded and marksman to shoot at a mile with no problem, and shooting a 6.5 creedmore to 1600 yards. When most say a creedmore is all but done at 1000, 1100 yards max.
I do have a couple questions, how many rounds have you fired after cleaning, and have you checked action  screws for  proper torque, scope ring screws also

[oregonmarkv]

Sounds like you need to try a different scope if all of a sudden it won't shoot a known accurate load.

[edgecrum]

Action screws from the factory were torqued less than spec. I found this out when I installed my timney trigger. They are torqued to Weatherby specs at this point. Shooting to 1600 with the Creedmoor was done with an SMK loaded to 2700 fps. As far as being a marksman I don't consider myself a marksman. I just play with my guns a lot. 1600 with the Creedmoor results in about a 5 foot group to be honest. My win mag at a mile maybe 4 foot. On an excellent day no wind I'd say my Creedmoor without flyers and me pulling the shot averages about a basketball at 1000?. I'm going to recheck groups today. Perhaps I was frustrated and not shooting my best.

[edgecrum]

Took it to 300 yards with factory LRX. I figure based on how the shots broke the gun is doing at least 25% better than the group shows. Anyhow the group measured 3 1/16 inch which works out to slightly under 1 MOA.

Weatherby told me I should expect around 80 or more fps increase at around 80 shots through the barrell and as it turns out velocities with all loads are going up. Factory LRX did average 3350 are now just over 3400.

[.257]

Glad this is working out for you

My latest gun addition is a Savage model 116 with a 26" #3 barrel in 6.5X284.
Loading a ELD-X 143 grain, it took over 40 rounds to find a load that would shoot, and it is still getting better

[edgecrum]

I had spoke to a guy the first time in customer service and explained my velocity issues, he sent me another box of factory LRX. I shot those, the velocity was still around 3350 so I called back and talked to a lady in customer service. Once explaining everything to her she agreed that I would send back some spent casings and my rifle to them to look everything over. I called back the next day with serial numbers to get an RMA. She asked if I was the guy with the 6.5 300 she had spoken to and I told her yes. She said hang on I have someone for you to talk to. A guy got on the phone -- I think he said he was the Head CS guy. He got on the phone and said he had some bad and embarrassing news. He said that when they came out with this caliber they did in fact publish accurate information regarding their velocity but over time the barrels weren't meeting accuracy demands. So he believes about a year ago they changed from a 5 groove to a 4 groove setup. The accuracy demands were met but they did in fact lose around 100 fps and they are aware of it. I told him how bad my bore fouls and he said that was to be expected. My gun goes from surgical clean to fouled even in the grooves in around 5 shots.... literally copper everywhere at the bore. He also told me they were seeing a good jump in velocity at about round 80 through the barrells--and this seems to be accurate as my velocities are going up.

The problem I have is that the .26 Nosler was king of the .264 caliber guns regarding velocity. Weatherby trumped that with the long awaited 6.5-300. Published the data, advertised the data, sold lots of guns. Unknown to the rest of us they have changed their barrell setup which lowered performance but are still selling the guns based on old data that is no longer accurate.

[cacsrx1]

The Barnes bullets aren't helping your copper fouling problems......., and 80 rounds through the barrel would not be acceptable for me.  These things have a short barrel life to begin with.

[edgecrum]

Or isn't acceptable to me either. Spoke with manager at Weatherby again and am offered no further solutions. I told them what I've expressed above his suggestion was try to return it or sell it. I asked for further box of another factory bullet to try but he wouldn't do that either.

[oregonmarkv]

Was this rifling groove change just on the Vanguard or o In the MarkV also. I bought a Accumark and a ULW when they first came out and they both shot good with certain loads and at published velocities. My ULW shot a 3 shot 3/4 inch group at 350 yards with my 140g accubond load going 3400 fps., a fourth shot made it a 1 1/4 inch group. I think there are other members who are getting published velocities and good accuracy.

[edgecrum]

I asked about the Mark V. He said those changed also. I took it that some original barrell were fine, if not great but too many weren't making the cut running up costs. Count the grooves in your bore. Mine is a 4 groove.

[oregonmarkv]

Well he must be mistaken or don't know what he is talking about because my MarkV ULW has 6 lands and grooves and no I DID NOT miscount and I marked every one and counted 4 times. So apparently it is just the Vanguards. Mybe someone else with newer MarkV can check theirs.
