Thread: 6.5 143 ELD-X, are they THE 6.5 hunting bullet?

Mine is at 20 inches, it's been a pretty slow barrel so far so hoping once it's broken in a bit things will speed up. I've done a couple of ladder tests with 2217 and 2225 and I've been hitting pressure pretty early in the charge weights and I think I've figured out why. It's a pretty rookie error, I had some discoloration on some of the cases after firing and it's looks like I haven't cleaned the lube off properly

I've made this mistake before so a bit disappointed I've done it again. Ah well onward and upward, I'll load up another ladder and get back on track.

Hoping to get up to 2950 but I'm miles away at this point, managed to get to 2740 today with 2225.

Just make sure you are not getting carbon build up cause that spikes pressure real quick.
Heavy loads of slow burning powder cause carbon rings real quick.

Yep I've just given a good clean out with boretech eliminator and I'll make sure my cases are clean next time. Charge weight wise I'm pretty sure I'm getting up there with 60.5 grains of 2225.

Believe me, it doesn't matter what fancy bore cleaner you use, if it's just using patches, there's no guarantee the bore will end up fully clean even when the patch comes out spotless. This is especially so with hard carbon rings that form in the throat. Even prolonged use of a new bronze brush will not shift them. You often have to resort to Autosol or JBs to get it out.

There is only one way to see if your cleaning has worked and that's a borescope. These days, there is no excuse for not getting one as Teslongs are pretty cheap. They can actually save you money as in not wasting components trying to find a load when the real cause is fouling.

I ended up getting a cheap bore scope and yep, I've got a carbon build up just in front of the chamber. I'll have to get some autosol and find out how to do an abrasive clean.

That will cause a big pressure spike.

Thats likely part of your problem. im no expert but have had similar issues with norma .308 brass, hitting pressure signs waaay before it should be. tried hornady brass and even that was substantially better than the norma.

For what its worth, so far im using 59gr of 2217 in lapua brass, fed120m primer to get 3050fps with the 26" no press signs at all yet. have loaded up to 60.5 to try and see how far from the danger zone i am.

Quite likely. To be fair though I'm 6 inches shorter on barrel length, that works out to 50fps per inch of barrel lost.
