I bought this Isaac Hollis 8 Bore Big game rifle - no clue what to load

[Kynoch2015]

Great idea! Always tried to think of ways of building up the front sight without affecting the originality of the rifle. Will be interesting to see how flat that ball actually shoots.

According to LoadBook trajectory tables ........

25 yards = +3.10" = 1518 ft/lbs ME
50 yards = +5.06" = 1479 ft/lbs ME
75 yards = +4.31" = 1445 ft/lbs ME
105 yards = +0.25" = 1405 ft/lbs ME
125 yards = -5.58" = 1370 ft/lbs ME

Impressive. Not a lot of velocity but tons of momentum looking at those ME values.

That is a slick way of getting a bit more height from a front sight

In a big round ball or conical wonder what the Tko numbers are

Today I also added a pin to keep the wedge captive in the stock so it won't get lost. Next trip to the range will test the increased height of the front site.

Well, back from the range. With the front site raised, and a slight increase in powder, here is the result.

0 yards = +0.00" = 1795 ft/lbs ME
25 yards = +3.50" = 1748 ft/lbs ME
50 yards = +6.30" = 1682 ft/lbs ME
75 yards = +6.60" = 1632 ft/lbs ME
100 yards = +4.60" = 1585 ft/lbs ME
125 yards = +0.00" = 1541 ft/lbs ME
150 yards = -7.60" = 1500 ft/lbs ME
