6.5X284 and H1000

[OIF/OEF]

I will delete the post immediately if it is no within good forum decorum "rhyme". Being a redundant question. Also I apologize in advance for the question kindof bouncing around. In my opinion the reason for the bolt click is the higher pressures from the jammed bullets

I am respectfully requesting for lead data for the following

6.5X284 using H1000 and 130 class and heavier bullets, any type of bullets, any discipline of shooting, any barrel length, any hunting or target or plinking.


Ive read a few places guys using up to 58.0 grains of H1000 in the 140-142 class of bullets. Ill admit I tried it with fairly good results as far as accuracy goes. All shots fired clover leafed at 285 yards.

Reasons for the questions is future knowledge and difficult bolt click after firing with the following loads.

Rifle is a MACII Tube rifle Krieger barrel 30 inches. No turn neck. New barrel as of yesterday. All new brass. Empty cases fired/new cycle in and out of barrel very smoothly. Something I noted was the only ammo tested that had the very stiff bolt click during extraction was the JAMMED bullets. I loaded 6 rounds or Berger 140 Hyb Hunting bullets over 58.0 grains of H1000 with .003 neck tension, Winchester Mag Primers, All 6 rounds were loaded with 58.0 of H1000. two test rounds were jammed .040 the next two were just touching lands and the next two were jumped .050

The bolt opens with normal effort until I reached the top of the stroke then it takes a good amount of force to get it passed the click on the JAMMED bullet rounds only. The rounds just kissing have the bolt click but not too bad and the rounds jumped have the leased bolt click. I did put a very light smidge of bolt lube on the base/web of one of the jammed rounds and the bolt click wasn't nearly as difficult to get passed. Again all rounds fired chambered very smoothly and were fired on new Hornady brass. Primer pockets on those fired cases are still very tight.

58.0 H1000
Winch Mag Primer
140 Hybrid Target seated .040 into lands
New Hornady Brass full length sized in RCBS standard dies
Bolt cycles perfect on empty brass new and unfired
bolt cycles perfect on same piece of brass that had click at top of round extraction after removal and rechambering in rifle slightly snug do to being fired but no click.
New loaded test ammo chambers smooth no issues.

It was 98 degrees outside about 90 in the shade at 1830-1900 hours.

Very Respectfully Submitted and Again I very much apologize in advance for the redundancy.

I used to shoot 6.5 x 284's for F-Open. My load was 54.7grs of H1000.. A friend of mine also shot H1000 and his was 54.8 I believe and yet another friend was shooting H1000 at 55.5grs. They were done with 140 Hybrids and they all were within a few ft. /sec. of 3030.. This was with 30" barrels. 58.0grs seems "Off-the-Scale" H-I-G-H! I believe that is where your problem lies with bolt clicking>>>NOT any jammed bullet.. Stay down BELOW 56.0grs and I GUARANTEE you won't have a bolt click!

That load is too hot. 56 grains is the hottest I would go.

I agree with shootdots....55.5 grains is the most I would go! I used mine in f-class with 54.8 H1000 with 140 hybrids.. shot very well and no sticky bolt lift

In my 6.5x284 that I used to have, my go-to load was 58g H1000 with 140g JLK bullets. I once shot that load in 93 degrees and got some primer changes, so decreased my load to the next node which was 56.5g. I shot the whole next season with the 56.5g load shooting really well for the life of that barrel.

My choice of H1000 was after reading an article about that powder in the 6.5x284 with the author going up to 58g without problems in his stock Savage target action.

Just my experiences.

Not to hijack this thread but what are you guys getting for barrel life from your 6.5-284's ?

 

[OIF/OEF]

thanks for butting in hoghunter Im joking brother heck id like to know also since ill probably be using H1000 exclusively. Ill drop the charge weight down and find a node for it. Man 58.0 shot flipping awesome too. Thanks yall

How many of the guys here who replied use Hornady brass?

Though I agree the load is to, especiallyou for match chamber, I would also add that the one time I used Hornady brass I had a sticky cam opening as well. That was with 52gr H4831sc and 49 gr H4350. Both with 142SMKs. I ditched it and went Lapua. That was about 13 years ago.

Have you tried any Lapua brass yet?

 

[smoking-brass]

I use nothing but lapua brass ... primer pocket issues if you go above 55.5 grains of H1000 .... I stay below 55.0 and have brass with 15 firings and still have good primer pockets. I annual every other firing.

 

[OIF/OEF]

No Sir Mr Fat but Ill be ordering some tonight for sure

Do you know what reamer they used for your chamber?

Mr. Fat That made me laugh. .

 

[ShootDots]

Here is another consideration for "primer pocket longevity". I purchased 300 pieces of the new "Shiraz / Norma" .284 brass. It does hold up better (in the primer pockets) than either the Lapua or the "regular" Norma 6.5 x 284 brass. As with everything new, it appears at least to me, that the "New Norma .284" brass needs a bit of "tweaking". Virtually ALL of my Shiraz / Norma brass has grown significant doughnuts in an inordinately short time frame>>>2 loadings / firings! Now I am not "passing judgement" on the brass as there are indications that others have not experienced this phenomenon. It may be that I have a lot of brass that is a tad soft in the neck / shoulder junction.. However, necking it down to 6.5 may well fix the "primer pocket issue". I would seriously consider doing exactly that.

I'm a huge fan of the PTG Norma Match chamber. Works great with 140s and 142s. The shoulder /neck Junction is easy on the brass and even if it did push up a doughnut the bearing surface is above it so no issue. I have had four or five different reamers and settled on this one for Lapua brass and 142s. I buy 200 cases and an 8# jug of H4350 and know I'm tossing the barrel once I get to the end of it. If it's late season I may run it until January to drive the nail in the coffin.

I have about 1000 spent cases going to the scrap bin. Makes me sick as they are still good but I won't mix brass in barrels so it's gotta go... they're sitting in three, one gallon bags on my floor. 80+ are loaded..... it's not an inexpensive round to shoot but for non -wind reading recoil pusse!$ like myself they are a fantastic 1k match round.

That is appreciated! Me too!

Crazy thing happened today during load testing. I reduced loads of H1000 to 54.7 and the bolt click went away and accuracy was better,all shots touching at 290 yards using CCI BR Primers and Berg 140 Hyb Targ jammed .020. The neck tension .0025

Thanks yall
