nice!

2017 Williamsport school venue, 1000 yards. That's four shots at 5 o'clock in the nine ring. The one above was the first of a five shot string. 6.5-.284

Hog, what twist ?

Hog, what twist ?

This was shot by a hunting buddy of mine/student, with an instructors 6.5-284 rifle. I wasn't really paying attention to any of the details other than it was a light gun. The only thing my friend recalls is the load was 53 grains and MAYBE it was Reloder 22. No other details known at this time.

Was hoping for “1:8 “. Lol. Thanks

I have a 1n8 shilen 30in 65284 going to purchase some 150smks any load data out there, I have H1000 Re26, H4350 Re22 4831sc which way do I go

I have a 30"/ 6.5 / 1-7.5 twist barrel coming to be chambered in 6.5 x 284. It is for the 150 SMKs. I plan on starting out with H1000.. My goal is: Excellent accuracy ABOVE 2900 f.p.s., although I don't see a problem achieving a "comfortable" 3000 f.p.s. However, I just read in "The Daily Bulletin" about VV N565. I read the write up from VV on their web-site. Honestly it sounds just like the properties of RL-16, RL-23 and RL-26. It further states that it's burn rate will be between N560 and N570. That would put it right on top of H1000. I would caution against H4350. Although an excellent powder and may work, even with a 150 class projectile, that powder is the main reason why barrel life is short in the 6.5 x 284. With that 150, stay with powders in the RL-26 / H1000 range..

H1000 is what I'm shooting now in the 65284 so I will stick with that hopefully it will shoot a few more shots

Ben, what do you think about H4831 in a case near 6.5-.284 capacity? I am going to test them in 6.5 x55 Imp.. I have a few 'kegs' of H4831sc but have been running RL-23 under a 142gr to great effect. The RL-23 may be a little fast for the 150gr.

I think that even for the 140gr pills out of a 6.5 x 284, H4831 is the "fastest" I would go. Having said that, the "weak link" if you will in the 6.5 x 284 case is the primer pockets. You won't have that problem in the 6.5 x 55IMP. So I think you can use H4831 in your case with the 150s. BUT I think you would still be better off with RL-26. But I would not be afraid to use H4831 in your case..

When I was shooting my GWI I got got great performance, accuracy, brass life and bbl. life with H-4831sc. The problem was every lot of powder gave me a different velocity per charge weight. I have a 7.5 twist bbl. coming as well and will be trying RL-23, RL-26 H-4831sc and H-1000 with the 150's in the GWI.

RL-23 has been stable with same velocity for given charge between two different lots in my BJAI and equals the best precision of H4831sc with just over 1gr less powder to get 2950-60fps with a 142gr. I've never used H1000...is it reasonably temp stable?

H1000 is as temp stable as any of the other "Extreme" powders. However, NONE are as stable as RL-16 or RL-23. They are amazing! Hey try RL-23 in the IMP case>>>it may very well prove to be the ticket!

Great minds think alike!

RL-23 (49.4gr) and a 142 Precision Ballistic at 2950-60fps has shot very well for me at 600yds and no difference is velocity between two lots I have shot. I won't change a thing until after the Berger's in Feb.. At that point I will test the 150's and will start with RL-23. I really like RL-16 in a 6.5 Creedmoor....I like it better than H4350. Alliant has acquitted themselves very well with this line of powder IMO.

Ben,
I don’t know how it is now, but years ago I ran 142 Sierra’s over VV N160 in a 6.5x284 and barrel life was only around 900 rounds down range. It was the go-to Powder back then.

Yeah I am sure Wes that it would eat up throats badly. But I plan on using H1000. I used that on my last 6.5 x 284 with 140 Hybrids and got a "comfortable" 1500 rounds..

Here is something interesting. I have a couple of boxes of 142 Sierra MatchKings. I also have a 500 count box of the 150 MatchKings. I took a handful of each and measured the Base to Ogive of each. Low-and-behold, MY measurements showed them to be virtually identical! The reason I was doing this, is because I may end up ordering a 6.5 x .284 Reamer for the 150s. I needed to know what would be a good freebore for the reamer for the 150s. According to my calculations, SHOULD you need to jump them 20K or so, a .200 freebore should be EXCELLENT! This will also allow you to easily use the 142SMKs or the Berger 140 VLD should the 150s not shoot to your expectations.

Very helpful Ben! Thank you for that.

I throated my 6.5x55 BJAI barrel for the 155g Cauterucio/147g ELD-M and when seating the 150g SMK at the lands, I am WAY out in the neck (have very little bullet in the case).

What I am trying to say is that I agree with you regarding the freebore needed for the 150s-shorter than expected.

BTW, my node with the 150 SMKs, BJAI, and RL23 seem to be right around 3020 fps or so.

Holy X-rings, Batman....3020fps!!!

Is that with Lapua brass Wade? How much RL-23? You are giving me heartburn as I just had two barrels finished for the 140-142's in 8tw and 8.5tw chambered for the BJAI. I gues I will need to get a 7.5tw ready after the Berger's. (Big sigh).....

Robin...seriously...
