2019 Rossi oversize bore
Just picked up a new Rossi in .44 mag and took it shooting yesterday . Barrel was leading up pretty heavy even though I was using GC bullets at fairly mild velocities , mostly Skeeter loads in .44spl and a few .44 mags with 9gr unique and the same 260gr gc bullet (WW alloy) . When I got home I decided to slug the bore and discovered it to be .43285 , This gun was made 15 April 2019 , so one of the new ones …….I guess they decided to go back to oversize bores again !?!?
Re: 2019 Rossi oversize bore
That is a standard sized bore for a rifle in .44 Mag according to SAAMI specs. It always has been.

Re: 2019 Rossi oversize bore
Obvious lay it’s going to need larger bullets cast specifically for it. I have been down that road some.
Re: 2019 Rossi oversize bore
Yea, I am going to have to try some bigger bullets for sure . I have gone up to .432 and still leading, even w/gas checks . Just casted up and water dropped some bullets a few minutes ago , going to give them a whirl soon as I can . Biggest problem is finding dies that will reload the ammo when the bullets exceed .432. I have a few sets here , but they will not accommodate anything larger than .432
Re: 2019 Rossi oversize bore
It was a shocker when , after I purchased a Marlin, to learn about the 2 specs. My bore was only .4323". Put a temporary stop to my quest, to figure out what paths I was going to take, to have a hand gun - rifle combo. Bullets that fit the rifle would not fit the revolver and bullets that fit the revolver leaded the heck in the rifle. Did not want to mess with my Redhawk, that I have had for close to 40 years. Sooo I opted to rebarreled the rifle, saving all the old stuff to be able to return to original if I ever sold it. Put a 1-16 twist .429 Douglas barrel on. Now one bullet, two firearms and the rifle will spin the 300 grgc cast pills accurately at cat sneeze velocities. Expensive route, but I got to where I wanted.
Funny how much can be accomplished when you throw enough money at it.

Re: 2019 Rossi oversize bore
Dunno why, but handgun SAAMI groove diameter specs are .429" and for rifle barrels it's .431". My Rossi slugged out at .432"+ and I had to do some fiddling with my molds and sizers. I shoot about .433"+ to .434"...

Re: 2019 Rossi oversize bore
BTW, it should shoot jacketed bullets just fine. My .44 Handi Rifle slugs @ .432. Fortunately I have a Lee mold that will shoot in it as cast, no sizing at all.
