6.5-284 Load development is finished
« on: August 14, 2004, 03:46:08 AM »
Yesterday morning with my 6.5-284 I shot a 5-shot group @ 100 yards measuring .340 and four of the shots measured .078! I think I finally found my load. All 5-shot groups to date with 2 powders and several different bullets have been under 3/4 of an inch.  H-4350, Federal Match Primers, Lapua Brass, and Hornady's 140 grain A-Max are the winning combo.
I am a very happy camper!

Yes, it is a big relief!
Now it it time to get ready to put it in the field and see what it can do in field conditions.

Pat,
Not yet.  
The International Tactical Rifleman's Championship is August 27-29th in Gillette Wyoming and then I will be shooting at a 1000 yard match in Pella, Iowa on September 11th.
The ITRC will be more challenging than the 1000 yard shoot in that all shooting is done from the prone position with field rests at unknown distances out to 1,000 yards (With the exception of the service pistol portion which is also steel and can go out to 50 yards but is generally 25 yards or less).  ITRC will be more challenging and practical, but the 1000 yard shoot should be just a lot of fun.  With both shoots, I am going to have a good time, learn, and meet some great people, while doing the best I can.  Last time I shot competitively was back in 1984 with a league PPC team.

Did some chronoing today and I have a speed of 2772 fps @ 15 feet from the muzzle. I need to find a way to calculate back to MV. It should be close to 2780 fps. This is what I hoped for. I thought I could get 2800 fps with this rig and I have done that, but my best accuracy load is 20 fps short of 2800 (but it is close enough for me!).
Load consists of 50.5 grains of H-4350, Lapua brass, Fed Match primers and 140 A-Max (Note--Which Is Safe In My Rig--Be wise in using this data).

Hello XPHunter,

Given your handle, this is probably the dumbest question of the day. . .but, inquiring minds want to know. . .and I'm only truly dumb if I don't ask a question that's on my mind. . .so here goes. . .

Are you, in fact, using an XP-100 or by chance is this 6.5-284 chambered in an Encore?  I've been kicking around the idea of getting an Encore with a 15" barrel in that chambering for a while so that's why I'm curious.

Thanks for sharing your loads and congratulations on such great success with your rig!

Safe and good shooting to you!   :D

In fact, I have two 6.5-284's in a specialty handguns (Xp-100 & MOA Maximum).  This is on the XP.  
I do know a man from another forum who has a 6.5-284 in an Encore (15 or 16 inch?) and it shoots 5-shot groups under .5 consistently @ 100 yards.  It groups in the .2's, .3's and .4's if I remember right.

Hi XPHunter,

It sounds as if that 6.5-284 may be a good choice in an Encore - especially if they're all as good as the one owned by your friend!

What do you know about the differences in chambering between a 6.5-284 cut for Lapua brass versus a 6.5-284 cut for Winchester brass?  Are they different?  Is one better than the other?  Winchester cases are much less expensive for the masses and they're good cases from everything I've heard.

Thanks for any insight you can share!

Safe and good shooting to you!   :D

The Winchester is good brass.  It is actually harder brass, which will allow to slightly go above pressure wise what you can in Lapua brass.  Lapua brass is overall the highest quality and tends to last longer.  In terms of hardness from hardest to softest you have Winchester, Lapua, Norma, and Hornady.  In a specialty handgun with a shorter barrel there is some advantage of using harder brass in that it allows you to safely push pressure up to get better velocities in handgun length barrels.  Since some of the internal dimanstions are different with different brands waht you could do is buy 100 or so rounds brass and then measure about 10 or so of them with a bullet seated and check the size of the neck with a loaded case.  Then, have your neck built just larger (3-4 thousands maybe a tad more) than your brass and you will get a match chamber without having to turn necks.  On my tight neck 6.5 I run from 1 &3/4 to 2 thousands clearance.
I have had sub .5 groups with both Norma & Lapua brass and I will be trying Hornady brass with my 6.5-284 MOA Maximum.

Hi XPHunter,

Thanks for the tips, that's really good information.  I'm assuming there's no difference in the dies for Winchester versus Lapua brass then?

Same.  I'm using the Redding Comp. dies with bushing inserts, seperate shoulder bump dies, and their in-line bullet seater.  Just to let you know I am relying heavily on those who smith and shoot at 1,000 yards.  I have several people I rely on in the industry also.  I just don't want anyone to think that I have done empirical testing myself on all of this brass. I do have Norma, Lapua, and Hornady 6.5-284 brass.  I was getting faster MV's with the Norma over the Lapua with identical loads. Not sure if that was an aberration or will consistently be the same.  Haven't yet used the Hornady brass but you need to work up loads slowly.  Winchester does not make 6.5-284 brass, so you have to neck down 284 win. brass.  I have a 100 ronds unprimed Win. 284 brass, but have not used it in the 6.5-284.  I had it since I also have a 284 Win. in an XP-100.

FWIW
If you are looking for accuracy, use a good barrel like Krieger, Broughton, Hart, Shilen, etc. and second use a good smith. Not a popular one nessecarily but an accuracy minded one.
Take the time to break it in, and practice good cleaning regimens, since you can ruin your barrel faster by cleaning it improperly, than you can by shooting it.
