Hello, first post from long time ML shooter and cartridge reloader.
I have Jeff's Scout 45-70 conversion.
He recommends sizing bullets to a fouled barrel. I havnt shot it. I have some Fury 265 which are .452. I resized to .451 and it wouldn't start. So I went to .450 and it free fell out the breech.
Do you think fouling will make for a proper fit with a .450 ?
Maybe just tweet a .451 ?
Knurling the .450 ?
Thanks in advance.

Right size to me is being able to start the bullet in the muzzle with your thumb and forefinger, then 2 finger push to seating. I don't compress the powder.

My SMI barrel was tight but shot 452 monoflex bullets the best. 451 SST were better but still tight. I ended up moving to Parker 275 grain BE and they fit way better. Don’t have to size them. They still have some resistance but minimal effort and it loads fine.

a .450 bullet might fall all the way through a barrel and a .4502 may need some push down and then a .4504 can't be pushed down. Proper sizing is very important, through away all your measuring devices and just size the bullet to fit the barrel. Then as you shoot the rifle you may need to size it just a wee little bit more.

Loose your measuring device and use your fingers. It’s a feel thing.
You will have to open your die up and start all over again since you went to small.
I adjust the die 2 notches till I can just barely get it started, then only adjust it 1 notch, then a 1/2 notch when I’m fine tuning the bullet to barrel fit.
I use the Fury 265’s and only run them through the sizing die once. I also use the same die with the 275 Pittman’s but I have to size them 3 times.

I got some great advice but not any discussion on my actual question which was how much does fouling affect bullet fit.
I'll use my undersized 450's to foul the barrel, to get on paper, and to assess the fouling impact.

I'll use my undersized 450's to foul the barrel, to get on paper, and to assess the fouling impact. It will definitely get tighter. If the bullet is already tight on a clean barrel you will want to back off. When mine was clean I could push the monoflex bullets down without to much issue. When it fouled it was all I could do to get them to go down the barrel. That’s when I switched bullets. My barrel likes a tight fit but it’s not worth the effort or getting one stuck. |

Do not believe that anyone could give you answer to this queston, but your barrel will FOUL out, and at times you may have to adjust fit for your gun and bullet, I only fit is the bullet that I am going to use, I have my bullets go down some what loose with little pressure to seat bullet, after a few firings it will be tighter, maybe a two finger push.If its tight again I will adjust die again, Now with my ML's if I shoot the gun put it up without cleaning its tighter, sometimes too tight, so best to brush out. If I leave one in the gun, (with the barrel MARKED loaded) I will shoot it out, and I am good, Now if you plan to use two bullets I would have (2) dies

Have found 10 full strokes of brushing (brass brush) in and out -after the last shot to work best to prep the bore for the next time out. Same as you - on if it’s already loaded and you shoot it out. My .40 cal is pickier with the slower powders vs the .45 with 4198. Have also found that dry conditions brushing is hardly needed. High humidity brushing is necessary. Brushes are also wear items - a fresh brush works best. I don’t clean anymore - just brush. Brushing also seems to keep the cold bore shot hitting in the same spots as the others and the speed within 10 fps. JMO |

I'll use my undersized 450's to foul the barrel, to get on paper, and to assess the fouling impact. I'm certainly no expert here, but it seems to me "how much" will vary from gun to gun and load to load as well as how we handle fouling. For example, some powders will be dirtier then others depending on the amount and your particular firearm. In addition, some of us handle fouling differently. I found that if I simply foul the barrel, tightness increases with each of the shots, and with time. If I shoot a few to foul the barrel and then reload, it might only take a little more force to push the bullet down the barrel. However, if I wait a day and try to load, it is much tighter. So, the way I handle fouling is to first foul the barrel and then run a single dry patch down the barrel. If I then wait a day to reload, I don't get that extra tightness. So, how we manage fouling has an impact as well. If both the nature and amount of fouling vary, the effects on bullet fit will vary. I think this is why most use "feel" for sizing. It works well for me. |

It works well for me. The key is to fist find a bullet size your barrel likes and several here have explained how to do that. Many factors affect the amount of fouling left in a barrel after firing. Powder used, bullet weight, barrel length, humidity, and the list goes on. While some loads foul terribly, others leave little residue, get your bullets sized where you can shoot the gun and see how it reacts. some Scouts have a choked barrel, if you go back and read some of the many posts you will find the discussions, IF it is? it will complicate finding proper bullet size, try it and see then get back with any issues. |
