What kind of outcome

[Andy Cross]

Just out of curisoty

QuickLOAD calculates this 40 g RL-7 load in the 243 Win to be 96,400# and about 3500 fps. Not bad for an 85 grain bullet in the older 243!!

Just out of curiosity could you run this load on your quick load calculator. .25/06 with a 26 inch barrel 1-10 twist shooting a 100gn Speer HP with 60gn of Reloader #19 behind it. Rem 9 1/2 primer. My farther used to run this load in his 25/06 and I always reckoned it was the main reason behind his poor brass life.

This load calculates out to produce 69,000# and 3530 fps in a 26" barrel. Unfortunately QuickLOAD does not consider primers used or barrel twist.
And he had brass life problems, I can't imagine why!

One of the bigger causes of brass life shortness in SAAMI chambered guns is the situation where maximum chamber and minimum cartridge exists and most factory ammo is made to minimum SAAMI dimensions..

my quickload gave the answer i posted..not yours..what did you use for an oal ???

again , an oal is required to produce results..all else is a guess.

QuickLOAD is a guess. Oehler 43 pressure system is a guess. LUP is a calculated guess. CUP is a better indicator but still a guess.

At any state, Andy's load is out there in No-No land for a factory action. Now, us benchresters with our spiffy custom actions we sometimes go that high just to get rid of one bullet hole of vertical. And yet we wonder why we get poor barrel life!!

Thanks for that

Thanks for that Jerry. Those pressures although they are an educated guess do seem reasonable. So I am not sure why the case life was so short. Mainly the primer pockets bacame loose. Stretching wasn't too bad. The chamber although it wasn't a tight one did need some neck turning of the brass for ease of loading he said. So it can't have been too slopy. He used Nosler brass mostly and a couple of years before he went into aged care reloaded some WW supreme factory cases that were nickel plated. He got a bit more life from those.

andy....
he was joking about pressure and case life....
25'06 max op pressure is only 65000 and he said you were getting 69000.....

again without oal there can be large pressure defferences.

case life can be shortened by following the die makers instructions of sizing to min every time, and then firing back out to chamber size.
neck or partial sizing helps case life.

yes short case life would be expected with your dads loads and loose primer pockets.

I was one of the "smart guys" who couldn't figure out how someone could use the wrong powder until one day I apparently used H4831SC instead of H4895 in my 6 BR. Couldn't figure out why I was only getting ~2600 fps from a load that should have given 700-800 fps more velocity until I eventually engaged my brain. It occurred to me that those powder granules seemed awfully large for 4895, but it didn't dawn on me until after I'd fired them. If it had been the other way around and I'd used 4895 instead of 4831 I would have been a very surprised, and possibly injured moron.

A friend and long time high power shooter and handloader blew up a pre-64 Model 70 when he hadn't dumped some faster powder out of his measure before loading for his 6.5-08 by mistake. Very chastened after that.

If it's possible at all to make a mistake the mistake will be made, sooner for some than for others. Just because someone hasn't made a certain mistake YET, doesn't mean that it's not possible - especially for someone who's never made that mistake or even many mistakes in the past.

Very Well Said

Very well said Larry!

I have been shooting for most of my 69 years, reloading since the age of 19 and avidly pursuing benchrest for the past 25 years. I have certainly made my share of mistakes even though I have always considered myself a careful, safety minded individual. All of us are human and Murphy's Law is alive and well. Anyone who thinks it will never happen to them is probably young and inexperienced; certainly foolish. I had an experience recently that would have cost me my left eye if I had not been wearing large lensed shooting glasses.

There are so many ways the wrong powder can find its way into the wrong cartridge. That's the main reason I have always discouraged the use of pistol powder to fireform rifle cases. Yeah,, I know, many have been doing it for years but all it takes is the right circumstances at the wrong time to cause a disaster. You just cannot be too careful when it comes to insuring the bore is clear before inserting the bolt and making certain of the powder you're are using.

Have fun guys, but most of all, be safe.

Good shootin'

i think it was said well...one powder on the bench at a time...then when all is set up, recheck everything....
