I just checked my other MarkV's a new 340 Weathermark and a1982 vintage 7mm WBY. and they both have 6 grooves. Maybe someone who knows barrels can chime in and tell us why a 4 groove would shoot slower and more accurate.

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.
My early order Accumark is the came as yours.

So today I shot 3 shots with 140 Accubond. A wise man shared his load data with me and it resulted in just over half MOA. The three velocities were 3372,3373,3393. I'll double check this load at longer range but with only very slight pressure signs it looks like I have a winner. 91g US 869. Thank you oregonmarkv.

You are welcome, that load will work for any thing you need to hunt with a 6.5 caliber and now you are getting 6.5-300 WBY. velocities. I would not be surprised if it shot better at longer range, mine shot a 4 shot 1 1/4 in. at 350 yards and I did not try to duplicate that just took it and was happy.

Took the aforementioned load to 300 today. Ended up with a 300 yard zero about 2.5 inch group, some of which was probably me. This VX3 scope has pretty significant parralax issues at 300 yards so I'm happy. After that I swung over to my 400 yard steel and used Kentucky windage for around 7 inch drop and landed 3 shots in about a 4 inch circle at great elevation. Now I'll load up 50 and the next shot will be at a critter.

Good to hear you got it all dialled in. Look forward to seeing some critters you get with it.

What have you guys been able to find (if much of anything) with the Hornady 143 eldx bullets? I have a Vanguard I'm doing load development on and have tried pushing a wide range of loads with the US869 as well as a few other powders but have been unable to find acceptable accuracy. I have had tremendous success with the bullets preformence on game and I would like to stick with this bullet as I will be hunting at longer distance (if I can get acceptable accuracy) Also how many loads are you guys getting out of brass? Thanks!

Welcome to the forum: I use only new brass for hunting but some of my target brass is on it's fourth load and the primer pockets are still tight. US869 and Nosler 140g acc. going 3400fps.

I've shot this gun twice at feral hogs. Both about 100 lbs. One at 225 yards, the other about 100. Both shoulder broadside. Complete passthrough with the accubond. Both dropped in their tracks.
