The 270 case head should measure .473. The 45/70 chamber will measure approximately.484. So the 270 case should stop at line 2. It will not go to line 3 because the bore of the barrel is .450

Thx Hank for taking the time to dissect a barrel to show the chamber of these Scouts and also for such a thorough writeup.👍

Yes, thank you Jeff for clearing up the muddy waters. I will add that when Jeff did my break action Knight (KP-1) I followed his advice on Min and Max loads works perfect. so why re-invent the wheel.

I have a CVA converted Scout and I too have a question about using H4198 load data. I am looking at the Pittman 300 Gr and was wondering if anyone has used H4198 at 65gr? Other load data which velocity would also be appreciated.

Thank you for that, is your TC Pro a bolt or break action?

What were your fps at the muzzle and would you feel comfortable shooting 300yds? Also have you ever shot 65 grains?

Also have you ever shot 65 grains? Mine shot the best at 63.5 grains. Sorry but I don’t have my notes in front of me to remember FPS. I’m comfortable shooting all the to a 1,000 yards but the question is what are you capable of doing with your gun setup and skills?

I'm a new member and do not have a rifle yet, but never realized there was a need to keep the bullet out of the "chamber area". So my first question is, if I want to shoot lighter loads do I fill the chamber with powder AND wads to fill the chamber?

You will want to keep the Wad out of the Powder Chamber also, I'm very recoil sensitive because of having C4-C5-C6 fused in my neck. I get great results shooting 56 gns. of IMR 4198 with a wool wad and the 275 gn. Parker Black Max Bullet. Good luck.

They say a picture is worth 1000 words and that pic on this tread is proof. I was wondering why Jeff says not to go below 55 gr of H4198. Now I understand why.

So my first question is, if I want to shoot lighter loads do I fill the chamber with powder AND wads to fill the chamber? You can use as little as 40 grain of 4198, however you will probably have pretty bad accuracy as the bullet will not obturate into the rifling to give it a spin. Without the spin the bullet will tumble and accuracy will suck. So theres a point here where you must use enough powder to make this even worth trying.

I went the opposite direction as everyone else when I had my conversion done. My black blue Scout is set up for the lighter sabot loads. It has the longer DI plug from Hankins. It takes most of the 45-70 chamber out. I wanted to shoot the faster powders like N110. I shoot bullets mainly from 180gr to 225gr. I tried sabotless but I prefer to shoot a saboted 40 cal 180 - 225gr bullet with N110 than a sabotless 45 cal 250 - 275gr bullet with 4198. That's the great thing about these conversions, versatility. You can set it up about any way you want it but there is limitations.
