was at a gunshow today one seller had remington 45-70 ammo 300 gr jacketed. New ammo & the box was marked " full pressure loads". Is this ammo safe to shoot in the modern day Marlin 45-70 rifles?

Yes, Lyman does separate the 45-70 into 3 levels. But some clarification is needed. First and foremost, the new Marlin's will not handle the pressure of the Ruger loads. You may want to do some research before posting potentially dangerous information. Not trying to offend you, just wanted to clarify one thing so no one gets injured.

A modern day Marlin 1895 is a hell for strong rifle.
The 300 is not one of the real hot loads. Marlin 1895 will shoot it easily.
The 300 might look strong while it is blowing up an old Springfield Trapdoor ect...
But modern Marlin lever actions can shoot hotter loads, and heavier bullets than the 300.

my err is lyman grouped the loads in 3 ways according to action strength 1. the old trapdoors or springfields 2. 1886 winnies & 1895 marlins. 3. ruger 1 & ruger 3. this the correct grouping. they do not say anything about the new 1895 marlins. I will contact Remington in the am & get some more info on this.

You're over thinking this and confusing handload data with factory ammunition. Remington's ammo is safe for a modern (post 1971) marlin 1895 which is what Lyman is referring to in category 2. Lyman makes the distinction they do for handloads that people look to them for information for.

The information you received from Remington is correct. Their factory loaded ammo is safe in Marlin 1895's (modern)

I contacted Remington Arms this am & asked for the ammo dept & asked them about the full pressure loads. their resonse was this ammo is OK to shoot in the new 1895 actions Marlins but not to use in the old springfields Or trapdoor rifles. The box is marked that way too.

I suspect that Lyman is being overly cautious regarding the #3 loadings. There are different 1895's in circulation. They (and their lawyers) are terrified that someone will insert one of their #3 loadings into a 100 year old Marlin 1895. The only remedy for that would be to add two more sub-categories - "Pre and post 1972 Marlin 1895" - to their manual. I can see why it's easier for them just to hold their position with regards to #1, 2 and 3. I myself would not be afraid to fire a #3 in my new production SBL but, having said that, there's really no valid reason to do so. Plenty of power with hot #2's...and like someone said above, there's no benefit in putting more stress on your rifle and abusing your shoulder.

Most of the reloading manuals provide data for the 45-70 cartridge stratified in the three categories noted above. The top-level loads designated for the Ruger #1 are not considered safe in any Marlin 1895. Personally, I do not use loads that are considered excessive pressure in any of my Marlins. The first thing behind that bolt is my head.

Think something may be missed in this thread, or, I simply did not see it! The Marlin 45-70 has a Maximum Cartridge Over All Length (COAL) of 2.550" (to be safely cycled in the Marlin action). The Ruger No.1 can chamber longer than 2.550" and that will most likely jam the Marlin Action. Second - the Marlin tubular magazine means you must use flat nose bullets. The Ruger No.1 is a single-shot rifle and can handle pointed nose bullets with much better ballistic coefficients.
