Is this the only guy that realizes this, I mean can this just all of the sudden blow up.

I have been out side of the box before when I first started reloading for my 300 win mag I had one speer manual from 1963 and was workin with IMR 4831 and IMR 4350, I tried the 4831 first and did all 3 loads in the book 78gr 80gr and 81gr, the first 2 did fine but the 81 grains blew the primer out and hot powder came out around the bolt and hit me in the face it accually scabed in some spots, but I lived to reload another day, the end.
 
I use Remington brass with near max loads of Retumbo and a 180gr IB in my 300 RUM.Brass life is not good ,I will get a sticky bolt if I try to reload it to many times.Try some new brass with the same load.

How many times have you blown up your gun?

Just sayin that cuz people I guess think if you get a pressure sign that means your gun in gonna blow up.

Just got some new brass.

This one has me laff'n !! You don't care about speed,but shot a 300RUM ?

Every gun I've loaded for has 2 sweet spots,ok fast and faster.

Back off .5gr and kiss the lands, I bet it shoots.

I have tried all of the above, I have shot some loads that where over 3400 with a 185 but they didnt shoot all that good, seems the charge I have now shoots really good but is very hard on the brass. Oh well I guess, I am going to try some retumbo again and see if that isnt any better

And I do care about speed but i will take a half inch small group over 100 fps.
 
I dumped H1000 and went to Retumbo on mine, because I was seeing indications of pressure on my brass and was seeing inconsistent speeds on my Chrono.

My load is 180 gr. Nosler BT with 96 gr. of Retumbo in Remington cases and WLRM primers. I'm seeing 3300/fps and 1" groups. I need to play with the seating depth a little and see if I can find the sweet spot and maybe shrink that group some.
 
I think I am going to go with a heavier bullet. I tried some imr 4350 and a 180 NBT and it was very accurate but SLOW I got some retumbo and I think I am going to try some 210 vld's

His problem is at the back of the case - not the mouth. Annealing will do nothing for this problem.

What do you think cat shooter. Am I getting casehead separation, why does it only do it after the brass has been fired 3 or so times

take a paper clip straiten it out and bend a little hook on the end. Use this to feel down your side wall if you feel a depression neat the case head then you gettin close to casehead seperation if you don't feel a depression your cases aren't getting sized down enough, annealing can help with this. As for gettting your accuracy back, your going to have to try different seating depths, once you find one that shoots better than the others, try different primers till you nail down the one that gives you the best results. Also do your shooting at 200-300yrds not 100, it'll give you much more accurate results.

He has early signs of pressure - it has nothing to do with sizing or paper clips. Annealing will not change the pressure signs, and it is very rare that primers show enough difference to make the added expense worth it.

I tried the retumbo with the same brass and the bolt didnt stick, but the primer pockets dont have much left in them, I bought some more brass and some berger 210vlds, as if the SOB didnt kick hard enough.
 
Make sure to load a grain over max then post it so the fear mongers can tell you your going to die. Then we can make fun of them. It always gives me a good laugh.

Just a suggestion but If I was you with that cal, I would be shooting the 230gr Berger hybrid, or the 215gr hybrid at least. with the new Hybrid Ojive Bryan Litz designed you no longer have to worry about the seating depth issues the VLD has.

Sign up ask around there's guy's on there that have forgotten more than most 10 handloaders will ever know colectivly

I just talked to a guy that has been shooting a 300 RUM along time and he said that he tosses his nosler brass after about 4 shots. Sounds like I am getting case head seperation. I am running a 185gr berger vld with 96gr of h1000 and its right at 3350 through the crony. Anything else shoots like crap, this is where the gun likes it, I have tried other powders like Retumbo and etc. and it likes 96gr of h1000 and shoots about .5 at 100

I just checked my Berger manual and your 4gr over listed max. Try the Hybrids, or the new Classic Hunter I mentioned previously, if you like Bergers you will love these.

Oh now you tell me after I just spent 50 bucks on the 210vld's I would have to order the hybrids not sure if I like that Idea. Lets see how they perform

Look up Kirby Allen APSRIFLES in Ft.Shaw he has (pardon the french) one helluva good brake design. Just talk to the guy a little

I think the berger manual is a little on the weak side, just my thoughts anyone I know is always way over what there book calls for.

I might look into a brake, cuz that thing really dishes it out on both ends of the gun if you know what I mean, what part of MT you from.
 
Cat shooter I realize that, I addressed it in an earlier post, and readdressed it. Good enough?

The paper clip is a tool to help you evaluate the condition of your case regardless of the number of firings.

I promise you that primers can make or break a load unless your shooting paper plates at 50yrds off hand.

I'm not trying to come across like an [beeep] (sorry if I am), but I shoot Long range, out to 1200yrds to date. Just cobbling a load together will not get you there period. A primer is part of the recipe, that very much does effect the accuracy of a load. If your expectations are such that you don't care about that kind of accuracy great! As long as your happy with the performance of your loads you can't ask for more.
