6.5x47 Users, anyone experience misfires?

[65BR]

Cold weather or ??? Considering use as a hunting round, so 1,000 yd shooting not the decision, 100% reliability is.....

Thanks.

I think if you use magnum primers and headspaced properly you should never have a misfire. The beautiful magazine feeding capability of this round makes it one of the most reliable around.

 

[JRinCo]

What misfires do you speak of.

To date I have used a 6.5X47 Lapua to take a dall ram, 2 whitail bucks, 1 mule deer buck and one very handsome 82 in" antelope buck.

As camac already mentioned, the round feeds beautifuly from a magazine and any bullet that you like can be loaded so that bullets are always seated above the shoulder conjuntion.

 

[65BR]

Congrats on your hunting success, like to hear what bullet you used.

As to misfires, basically failure of the "SMALL rifle primer" igniting the charge.

I have heard this - though very rare with this ctg. Not overly concerned, but before I would sink $$$ into a project, would be interested if anyone had trouble w/ignition, esp. in cold weather, as I believe that is where the troubles happened.

Thanks.

Cold weather ignition problems don't exist if you use magnum primers. Both my 6.5x47 Lapua & 6x47 Lapua had ignition issues after -10 degrees.

If you are converting another 308 class bolt head rifle you also need to ensure a nice central firing pin for the small rifle primers. My recent 6*47 L conversion was hitting slightly off centre. No misfires but I bushed and recentered.

havent had a misfire in shooting over 3000 rounds of 6.5x47 L,,,,

I haven't had a misfire either with my 6.5-08 AI made on the small primer lapua palma brass either.

 

[65BR]

Great Info gang, RC- looks like a Hot Magnum spark is what you want in COLD weather.

Camac- good point, I am building a Borden Alpine, so no concern on trueness, should be dead center, and seems to be tight on spec so no concern on needing bushed. Will check with Jim Borden just to be sure but it looks like a tight/small hole there vs. say a Rem 700 factory.

Tx65/Arne right? Good to know.

Ok, looks like any random misfires/ignition issues are either std primers in VERY cold weather, or primers that were bad to begin with so that answers my question well, unless anyone else wants to add anything.

Thanks much guys.

Thought I'd pass on a link/article someone referred to me from another site if anyone wants to read.

65BR,
I'm strictly using 130 Berger VLD hunting bullets for all of my shooting in 6.5X47 Lapua, on top of H 4350. CCI 450
Wolf primers are the only ones that I've known to not light, the cups are supposedly harder.

 

[65BR]

Thanks much Jerry, I have not yet used that 6.5, but the 130 Berger has always looked to be one of the best hunting bullets for this round, and perhaps a 260 as well for deer sized game and I have wanted to try it.

Interestingly, I have alot of Wolf primers that I had bought for a former 6BR.

What primer do you tend to prefer? CCI 450 Mag? Thanks.

 

[JRinCo]

CCI 450's are the hands down favorite everytime the subject comes up on any forum.

 

[65BR]

I knew they were favored in 6BR, thanks sir.

German did a recent article on primers and it once again hit a lot of notes on what we had been seeing over here. Wolf primers have a very soft spark. Generally the thought is you want to use the mildest spark you can get away with that still gives you consistent ignition. Wolf work well in chambers that use the medium to faster powders that ignite easily. By his and other reports it appears you need a bit more bang to get the slower ones going especially in cold weather. - Wolf/BR4's might work best in tropics or warm climates in 6BR but might get better results from rem or 450's in the cold.

link http://riflemansjournal.blogspot.com/2009/06/primers-small-rifle-primer-study.html don't think he tested the 450's by memory but they should be as hot or hotter than the rem 71/2.

I'm having problems with Wolf small rifle-223rem primers lots of hang fires in my .223 ack yesterday.....Now I understand they have harder cups for the autos.....It isn't a small rifle primer problem because every thing else works fine. I guess I should have bought wolf small rifle not the .223 kind......Now I have to figure out what I am going to do with 4900 of them

 

[65BR]

I was thinking on that very part above, about how a Small Rifle primer may be more reliable with faster burning powders when you riding the edge. I take it the 6.5L uses faster burning Primer than say a 6mm version. None the less, looks like a good hot Primer should spark fine for reliable ignition in adverse conditions.

Thanks all..

65BR,
I'm strictly using 130 Berger VLD hunting bullets for all of my shooting in 6.5X47 Lapua, on top of H 4350. CCI 450

My load too! About 40-41 gr depending upon the lot, accuracy, ES/SD, etc. Was getting 2800 fps from 26" Krieger with 40.25 gr. New lot necessitated going to 40.8 gr and getting 2880. .001" neck tension. Ten thou into the lands; don't load the round unless you're sure you're going to shoot. Other wise = stuck bullet. Shot a .344 MOA @ 500 yd a few weeks back with a dirty 700 rd barrel; 900+ total so far.

I did all my testing last winter @ 5500'-6600' in 20-40 deg F temps in Utah. Started with Fed match primers and ended up settling on CCI 450's. Never a hang fire.

[65BR]

Thanks much Alan, looks like a 22-23" rifle would give perhaps 2780 or so wouldn't you think w/130?

Thanks.

 

[M14AMU]

No sir...none at all!

Only problem I have is that every time I pull the trigger on this Jewel I'm shooting....I have an orgasm!!

 

[500 meter ram]

I have had some problems with CCI 400's but none with 205's or 71/2.
