6.5 cm load too hot. what now?

[Tokay444]

I think there are multiple mistakes here and I feel OP needs to step back and really understand what he’s doing before he blows a gun up and really hurts himself or some unfortunate soul who just happens to be at the at the same time he does.

 

[milboltnut]

yeah I agree.... after seeing the pic of the scale. For sure.

 

[HandgunHTR]

Still haven't concluded if he is using a powder measure or not.

If you are, how did you clean it after loading the .300 BO that morning?

 

[johnfkingmatrix]

I would say that the operator not only oiled the bolt up well,but he also managed to get it on the cartridge and in the chamber.Good old rainwater causes enough pressure problems with target rifles fired on rainy days even when trying to keep the cartridges dry.

ty for answer. not sure why everyone has devolved into being mean and acting like i put an S shaped case in with a 27cal bullet quad loaded with a mixture of pistol powder ammonia and fertilizer, when i clearly pulled and re weighed. i also test weighed a nickle, accurately.

if excess oil will do this, and i admitted to loading it with oil, how is this not the obvious cause? "usually its the simplest thing"

not being argumentative, and im sincerely grateful for EVERYONE'S help. given the evidence, can someone help me understand why its NOT just excess lube

i have an rcbs powder meter, when im done i crank it dry a few times, then i pour new powder in and run a bunch of cycles thru. after lighting up a cigar, of course

There's a couple nice rcbs 505 scales in classifieds.
I only use a beam for loading, despite what you believe is weighing accurately, your scale is sitting cattywompus.
FWIW ya really need thick skin with this crowd!!

It’s simply because the way you went about it, from not pulling the powder from the very start, over lubing the action, trying to drop a bullet down the barrel to the scale resting on a book. Those are all the signs of someone that doesn’t understand the basics of gun maintenance and reloading. We all have to start somewhere and I truly hope you’ve learned a valuable lesson but to be honest we still don’t really know what happened.

Go buy yourself a digital scale. Obviously you get what you pay for, but they can be purchased for under $50 and most come with a calibration weight. Then buy a new container of IMR 4451. You've likely gotten the message regarding a "dry" chamber and bore. Weigh your test charges, don't throw them with a powder measure. Measure your bullet diameters.

Unfortunately, I doubt you are going to be able to definitively figure out your mistake without trying to replicate it, which would be a bad thing - you got really lucky the first time. But by starting over, with your newly aquired knowledge and fresh components, you can get some confidence back and move forward.

RCBS will send him a leveling screw. The scale is probably fine & will work well for a beginner once repaired. It's a wonderfully simple device... *almost* idiot proof.

The real answer to most problems is rarely to throw more $$ at it (unless you have a gub'mint contract). Digital creates a whole 'nuther set of things that can go wrong.

When I seen the scale picture, first thing I thought was, "Dam, his bench is at a 10 degree angle".

Johnny, the scale is the heart and soul of handloading. It should be leveled port and starboard, as well as fore and aft. That is why many of us set up our scales on leveling plates, even digital scales.Using check weights should be done every time you set up for a loading session. When the scale is zeroed it should return to zero every time the beam is moved, no up or down a little bit every now and then.

I agree, there is nothing inherently wrong with a beam scale, I used one for years, which I still have, but never use anymore. If I were him, I would definitely fix the scale he has also. Like everything else technology marches on, some embrace it and others don't.

thanks for answers, at least i was within the limits. Yeah ill pull them and re-weigh... i also loaded some other rounds that day for 300 blk with same scale setup and everything was A-ok.

I guess ill start them off at 36.6?
What would cause that giant primer dent ? i noticed when i was putting the primers in they were pretty hard to get in there...

its winchester brass.

Seems my COAL is the big issue, based upon previous post.

Seems my COAL is the big issue, based upon previous post. My neighbor just ruined a 22-250 from loading wrong powder. He said it blew off the extractor and deformed the bolt face. Also got a shot of hot gasses to his face. This guy shoots and reloads weekly so is no novice. I have been reloading for five decades and thousands of rounds and and did it myself a few years ago. Only cost me a new bolt handle. I was lucky and so was my neighbor.

Just sayin

update: its definitely something wrong with my reload. i cleaned chamber, fired a factory no issues. fired a reload and it locked up. ill order scale part but if its not powder, would it be a case sizing issue? is there anyway the full length size die didnt work the full length and the bottom is fat? or is it simply too much powder for my gun.
also ill reweigh bullets to make sure not a packaging error. really at a loss here

It seems that load is simply too hot for your gun.

I really cannot believe you fired another one of those same reloads!
Butt since you did, you might as well show us what that case looks like since you eliminated the over oiling part.
This great bunch of guys here will stay with you on this to help you but you better have your thickest skin on, your going to need.

I‘m wondering why you set the OAL so short with that bullet. I would like to see you reduce the load 3 grains and move the COAL out to 2.820 or further.

Can you measure the case overall length of the “locked” case as I grasping at straws here.

 

[kojaone]

Did you leave any powder in a mostly empty powder thrower for long time?Did you leave the lid off your thrower or container?Dry powder.I recently read on 6.8 forums of some reloaders drying out powder by putting in dish , in a dry area ,for week or so,velocity increased a 100 fps in a 6.8 case.Try changing to a different powder or a different lot.I was shooting close to max loads of cfe223 in a 6.5 grendel,changed to a new bottle that was way to hot,checked that bottle with other calibers,way to hot,chucked it,Got a new bottle with different lot numbers.All good,doesn't happen often,but it happens.

Are you Shure you didn't confuse you cigars with something else, just asking

 

[milboltnut]

call RCBS and ask them for a leg for your scale.. you'll get it for free.

In all seriousness I would get scales fixed and verified, scrap all previous loaded rounds and bottle of powder in case it got mixed with another one. Start over fresh and be safe.

 

[Richard Coody]

Do you have calipers, headspace bushings, Hornady overall length gauge.

If that fired piece of brass is In one piece measure base to shoulder datum just for grins. Compare that to your sized case and a factory round.

Chamber a piece of your sized brass. Does it chamber easily?

Use Hornady comparators to measure base to ogive on you reloads and a factory round.

Use the Hornady overall length tool and one of the bullets you are using to find the distance to the lands.

There are utube videos on all these activities if you need them.

Get back to us when you have completed these task.
