low psi 30/30 load

I've seen thousands of reduced loads for 30/30 but the source of these loads would make me hesitate. TB is an established source. Seen loads with 2400, 231, Unique and many others but they'd be a jump of faith.

Buy the Lyman Cast Bullet Handbook. They have laboratory proven data using small amounts of pistol and shotgun powder in as many different cartridges as you'd find in a normal reloading manual.
The cast bullets can be swapped for jacketed bullets of the same weight for heavily reduced loads so it's still useful to those who don't shoot cast.
 
This is the information from the Basic Manual that can be downloaded from the Hodgdon website;

160 GR CAST
Powder-start-velocity-pressure-max-velocity-pressure
H4895-17.5gr-1351-15,200-21.0gr-1562-23,100
H4198-15.0gr-.1420-15,000-17.0gr-1616-20,600
Trail Boss- 6.5 gr-997-20,500-9.0 gr-1195-29,100

I'd suggest that Trail Boss in this case and in many other rifle calibers is a poor choice. Notice how it gives a high pressure with a far lower velocity than for the other powders? This is simply not a wise choice for a rifle caliber powder IMO.

Now this all changes for handgun calibers where it works very well. But it's this issue with high pressure for low achieved velocity that brought me to state that it's not a miracle powder in my earlier post. And this issue shows up in other rifle calibers where it is listed as an option with the same issue.
 
There are lots of ways to get reduced loads, TB is just really easy and it's the first one I reach for these days. I actually just restocked my TB GROUSE loads for my 300WSM. POI at 20-30 yards coincides with the first dot on my reticle. Works good for popping grouse in the head.

Pressure is about 23000 PSI, which is no worries as the WSM can handle 65000PSI

A little extra pressure can be a good thing, for ensuring brass expands and seals well in the chamber

Pretty much the point of trail boss is to get the pressure up to an efficient level while being too bulky to overload. You miss the point of trailboss.
 
I am running 165g cast from bullet barn in my 30-30.
14.5g IMR 4198 with a mag primer.

Getting 1.5" groups at 50yrds. Very light recoil.
I played with charges up to 22g but could not get the accuracy I wanted.

I have some .311" lead cast coming to try out.
