You have very good points. I'm going to back up a bit and try to make the original point.
I see...I would suppose this is your explanation of why you edited your post that tried to take me to task completely?
These are just my opinions.I consult with manufactures regularly, take note and sometime get things right. Maybe sometimes wrong.
This is good...we all make mistakes...nobody is perfect...but the main difference between me and you is I will admit it...and this is something you haven't done yet...
What I don't do is exceed any manufacturersrecommendations.
How can this be? If your Chrongraph is in good working order...then please explain how you can achieve 3600 FPS in your 280?
It doesn't mean it cannot be done. People have pushed the 45-70 over 28,000 for years.
Yes..and
Safely too I've seen a lot of split brass too. Not all brass is created equal. There is a difference in the strength of the .450 Marlin case than in the industry standard 45-70 case.
Are you saying you've never caused the split brass...and it's only been because of a manufacures defect? Hmmm...I would bet you have seen quite a bit with your 280 loads...
Well...since you won't admit that your 3600 fps 139gr. 280 reload in a Handi rifle is a mistake..one way or another...this statement of yours cannot be true...
Part of the problem of the pressure range both calibers operate in is that traditional signs of excessive pressure do not apply.
Oh Really...did the rules of reloading just magicly change for these 2 cartridges? I think not...the rules do apply for both the 45-70 and the 450 Marlin
You can be over 50,000 easy and never stick a case or flatten a primer and without putting a strain gauge on the receiver, you have no clue as to how close to failure you may be - or - may not be.
I've loaded extensively for the 45-70...and high pressure signs show up quite frequently...if the charges have been pushed...and depending on the rifle some at much lower velocities...because each rifle is different...and another thing...all one has to do is to have their reloads tested...granted...it's not the cheapest or quickest for results...but...the results are varified in writting by the testing faucility...I've had some of my 45-70 loads tested...and know full well what the pressures are in them...and have talked with the good folks at Hodgdons on my loads...this is something I suggest you try...instead of just paying lip service to what is published...
I'm sure if NEF says it is OK to push a 45-70 to 43,000 you are good to go. I do know they will instruct you not to load past the lever action standard and not to try the Ruger 1. Anyone really wanting a good answer should call the factory.
Tisk...Tisk...Tisk...do you even read the litriature that comes in a Handi Rifles box...if so...please consult your Owners Manual if you even own one...1st page...2nd paragraph under the first red warning paragraph...and I quote" H&R assumes no liability or responsability for injusry or damages resulting from misuse,neglect,alterations,the use of parts not of our manufacture..(here's the biggy)
or the use of ammunition that is faulty,handloaded,reloaded,or not made to the above standards.What this means is they will never tell you that it is ok to load above SAMMI pressures for
ANY cartridge...period...What they will tell you is that those that have haven't reported any failures with them......because of liability... like if someone was stupid enough to try a push a 139gr reload for the 280 at 3600 fps all the time...and when..not if...it blew up and hurt the shooter or bystander or damaged the rifle...they wouldn't be held responsible...
While the .280/.270/30-06 are all 60,000 or better, they all push significantly lighter projectiles.
...yep...this is correct...
The Ruger 1 loads for a 45-70 are 50,000 cup as I recall. Yes, 50,000 cup is less than 60,000
Sorry ...but I had to break in here...did you not know that the CUP and the PSI for the 45-70 are basicly the same?...apparently not...
+ but the impulse function in trying to move a 300 to 500 grain bullet from a dead stop to go in a 45-70/450 Marlin is significantly more stressful than a 130 or so grain bullet in a 270.
Not really...this would all depend on the total amount of impulse the standing breech or bolt is recieving...and since the 270-280-30-06 pressures are significantly higher..and the impulse time is significantly quicker..the fatiqued on the firearm is higher...load the 45-70 or the 450 Marlin to the same pressures and then it would stress the firearm more..
Not to mention, the reaction is directly in the direction of ones face. Hey, I am not claiming to be a firearm designer and don't think I know better than the factory.
This is a good thing...
It is like comparing stomping the gas or pushing down more slowly. One way you are more likely to spin a tire. Why? because you can only apply so much force to overcome momentum (or in this case - the lack of) before something snaps. A man's shoulder can understand the difference, why can't his brain?
I haven't a clue...why can't you...?
If the factory advises not exceeding lever action levels - why would anyone intentionally do so? Do they somehow know more than the folks who built the thing?
The factory doesn't advise you to not load over Lever Action Levels...they advise you not to load to over SAMMI Standards for the cartridge...and in the case of the 45-70...these are kept at safe trapdoor loads...for all the old rifles that would not take the higher pressures...this is why there are many companies offering high pressure 45-70 loads...that have been proven safe in the Marlin 1895 rifles and in the Handi's...yes...I said proven safe...not by some arm chair ballestician who thinks he has all the answers...but by reputable companies who have thuroghly tested their products and the rifles it is shot in. The argument over the strenghts of the 45-70 have been around ...and yes...it has been loaded from mild to wild...but...while the Handi rifle isn't a weak action...it isn't as strong as a ruger #1 or #3..or a Siamese bolt action or a Browing 1886...or Highwall..or a .C.Sharps and Shiloh model...so the very highest pressures that
could be loaded...shouldn't...
The .450 Marlin is a modernized standard which is intended to operate at 43,000 cup. It is designed in every way to operate at that pressure.
No argument from me here...but...if you are implying the 45-70 has as high of pressure to achive the same velocity...that isn't the case...and this is due to the internal capacity differences between the 2 cartridges...
-just a rhetorical question:
Is it even conceivable that the factory (any factory) has had a bad batch of steel come in at some point in its history?
Sure it's concivable that they have had a bad batch...but I think they have enough safegards in place that they won't be shipped out and sold...
If NEF's manufacturing tolerances and/or product confidence/QC were as high as say Ruger, T/C, or Browning, why do you think they require you to send each barrel back to be checked, fitted and head-spaced?
Man...you just don't get it do you...the reason is simply they are produced differently for different cost and for liability reasons ...What we are doing with our barrels ...they know about...believe me...they do...from the Board Members and CEO of Marlin all the way down the management line to the folks at the plants...they know...namely because we told them what we are doing and why...did you even read this announcement...
http://www.graybeardoutdoors.com/phpbb2/viewtopic.php?t=64112 Are they inspecting for a possible manufacturing defect or fatigue? I don't know and I haven't asked. But I guarantee there is a reason.
Sure...they inspect them when they come back...it's part of the cost...
NEF isn't a bad company. I am not saying that they are. I think they produce a very good product for the money. However strong the fan base is here in this forum, it is unreasonable to expect perfection from them and if they establish a maximum safe level for any of their products, I'll bet they have sound reasoning for doing so.
They are a good company...one that given the oppourtunity I would buy stock in in a heartbeat...and again...the levels given are just as most other munfactures...it's called liability...
NEF isn't even competing in the same market segment as any other American manufacturing firearm company that I know of. Having watched them a while, I believe they are adding newer designs and expanding their product line to improve their position. The folks at NEF aren't stupid by any means. I suspect full well they know where they have been and where they are now and where they want to go. If they establish a limit - stick to it.
Nope...not really about limits...some folks if you read about them...are trying to change that...
Statistically speaking, there will always be those products that perform exceptionally well and those that fall short. So if someone doesn't get the same results as someone else it doesn't mean that either are wrong or either are right for that matter
Are we talking about the supposed 3600 fps 280 load again?...
Manufacturing tolerances stack up - sometime to the good and sometime to the bad. It is a fact of all manufacturing. Manufacturers take this into consideration when the establish their standards.
I don't know what book your reading this out of...but not all companies are like this...some...actually care and if there are to many problems they change...and this is what's trying to be done at NEF by Diana..
If a product's factory produces a specification or recommendation - you will do best to follow it. People drink and drive every day. Should they?
Ahh...then why don't you follow your own recomendations and stick to book loads instead of proof loads for your 280...or at least admit your mistake on the velocity...cause quite frankly...nobody believes it anyway...
