    Great caution must be exercised! My Lee loading manual lists 2400, as giving highest velocities with 300 grain jacketed bullet.

    11.4 to 12.5 grains. These are handgun loads. 735 FPS with 12.5 grains of 2400.

    Assuming you use an appropriate diameter bullet, and a load recipe from a reputable source (e.g. a reloading manual or powder manufacturer web site) and the overall length of the loaded cartridge will chamber okay, I can't think of any reason you couldn't.

    hello You did not say anything about condition. and maybe it's history of use as to how much it has been shot I would want to let some of at least my friends / prefer those that hand load And know some danger signs to look for. to look at gun it is hard to get a GUN SMITH to give his opinion But might not hurt to ask what he would charge . to look it over.

    It's not the bullet weight, it's the chamber pressure. So, yes it is safe to load a 300 grain bullet, provided the chamber pressure is kept to the acceptable limit.

    I think it can be done safely. OAL and a crimp grove in the right place on the bullet will be important functioning considering's.

    My Lyman 49th doesn't list rifle data for larger than 255 grain bullet, but its an older book.

    I would stick to regular 45 Colt data not the enhanced Ruger or TC data for 45 Colt.

    I load unique for my friends Pietta with cast 250 bullets. He like them.

    They have pistol data for 300 gr Sierra bullets here COL 1.670 and low pressures using Hodgdon powers.

    Amount of crimp for tube magazines can depend on how you use them. You can get by with less if you empty the magazine, rather than keeping it topped off.

    llama girl,

    About all that I can say is this: Rossi manufactured their Model 92 in .454 Casull. If the Rossi can handle the .454, then it should be safe with properly-loaded .45 Colt ammunition:

    Thanx for all the input. The rifle is new less than a box have been shot out of it. I got some info from a book at the gun store. Just the same I will stick with what I use now 250 grain slugs. I did find info on 185 grain slugs that I didn't have. I will try that next.

    Here is a link for you. I am pretty sure you can figure it out for yourself. If not, your rifle will let you know.

    Be very careful about overall length. If the completed round is too long it may chamber OK, but if the bullet is touching the rifling you are in for trouble. Ejecting the unfired round can disassemble it and spill powder all over the action.

    Been there, done that.

    llama girl,

    Even when loading into the lands you'll be okay if you start at the starting load and work up.

    It's saved me many times doing it that way. I was loading in brand new territory where no data was available. I interpolated what should have been the starting load and reduced a few grains. It's a lot easier to work up than back down after your firearm came apart.

    Lesson: Work up...not a problem. Working down won't work. Period.[;)]

    It's safe as long as you find data that is appropriate for your 300 gr bullet. The bullets require a lower charge than 250 gr or other bullets because they take up more of the case capacity and because they are heavier and longer and harder to force into the rifling.

    There may be slight differences in safe charges even between different 300 gr bullets.

    You cannot assume a charge for a lighter bullet is safe for a heavier one just because some of them may fit. The powder would be going off inside a smaller space and would produce higher pressure.

    I would not recklessly assume a 45lc 92 can take 454 pressures just because they made some 92s in 454. First of all the case is different. Second of all they may have had to tweak the design to get 454 to work in a 92. They may have changed the grade of steel or the heat treatment of the receiver, bolt, or locking parts. These changes may not have been made to the rest of the 92 line.

    I also would like to know if it's safe to use automatic transmission fluid instead of brake fluid in my new truck. I don't want a lecture from self appointed truck snobs. I just want to do this so I can save .05 cents even if it may risk my life and others around me including my new truck.
