It is speer 350 grain bullet, IMR, 4198 50 grains. Thanks for your help.

I've got one. I've also owned a Remlin and a couple pre-Remington guide guns.

I would not do it. That's a max load per Hodgdon. Given that, I would not shoot those without working up to them in your rifle first. Moreover, their data is with the Hornady bullet, not the Speer bullet, and I do not think the COL will fit through your rifle so even if safe, you're probably going to have to single load it rather than magazine feed them. Finally, recoil, in those rifles, gets rude somewhere around 1800 fps, and those will probably top 2000, maybe 2100.

I can't think of a reason other than laziness not to pull the bullets and start over so that is my advice.
