I am new to reloading and I want to reload for the Broomhandle Mauser. The bullet diameter is 0.308, same as the M-1 Carbine. If I was to use a 100 grain jacketed bullet for the M-1, would it work for the Mauser? I am not sure if FMJ RN rifle and pilstol bullets would be the same size even though the grain might be the same. My main concern is a rifle bullet length being to long and cause a compressed load in the Mauser cartridge.
7.63 Mauser

I don't think you should. I damaged a colt 1908 barrel in .380 acp when I first started reloading. I was using 9mm bullets in the 100 grain range, after a while cases started getting stuck in the chamber and I needed a rod to tap them out. It seems the chamber ballooned a bit and the cases were a little ballooned shape. The slide was hard to move back and forth so I used a grinder to slim down the chamber area, now I've been looking for a barrel and firing pin parts for the past 20 years. You keep on hearing that if you use a heavier bullet and seat it further in the case, pressure increases.

do not ever yse 7.62x25 in a mauser broomhandle 7.62x25 is a very hot round not only that the jackets are made from steel its a soft steel but not as soft as copper
This argument is almost as redundant as the 9mm Luger or 45 ACP one.
There was another thread on this which was hotly debated.
Personally I would guess that 7.62 x 25 is too hot. But I do not own a Broomhandle and unless I've a lottery win...likely will not any time soon.
But if I did...I'd not run FSU Milsurp through it...seems like a bad decision IMO

I personally use the 90gr Hornady XTP so I can't share my own experience, but since no one is willing to answer the actual question (that happens frequently) I thought I'd share my thoughts.
To address your question - I've read that some people do use the _110_ gr bullets for the M1 to reload for the broomhandle. That gets mentioned pretty much every time someone asks that question. Search further back in this forum.
I've never seen or heard of a 100gr bullet made specifically for the broomhandle, I suspect that the load data was developed for the M1 bullet being adapted for the broomhandle.
Several things worthy of noting, and, yes some of this is being overly cautious, but that's how reloading is:
When you start loading you will see that the case is far from full so your chance of a compressed load is low.
When you use a heavier bullet, you use a lighter load, so see above.
Obviously do start at the minimum the manual recommends.
Seat as little as possible withing the parameters above.
All of this should give you a safe starting load. You will note I did not say anything about your cartridge's overall length being within the max / to fit the magazine. That's because I would single load the first trial rounds if they are too long for the magazine.
Now watch for pressure signs. If none, start adjusting your seating depth _very slowly_ until you are happy (seating depth affects the pressure VERY quickly).
Still no pressure signs? Start increasing the powder _very slowly_ until you have consistent action cycling.
Having a press available at the range for quick load development or having an antique broomhandle makes this process go faster. Good luck!
