To the testing, the Lehighs 168gr CF are very accurate with multiple first round hits on 4"-5" balloons at different angles from 6 degrees to 48 degrees out to 250m and centre hits on a 10" steel plate at 300m and 400m.

151gr HP cast bullets were so so in accuracy but I would be happy taking a goat deer pig out to 150m as I was getting first round hits on balloons to 160m. I was getting an ES of 22 with ADI AR2205 powder, have been trying different seating depths with little gain. May need to try Trailboss but its accurate enough for bush hunting range.

Lehigh 168gr Controled Fracturing


5 shot 100m accuracy, easy sub MOA



100m cast 151gr Hollow Point,

Thanks to the spammer for bumping this thread.

Are those cast loads subs or supers @tikka ?
I tried to develop a subsonic load with the 151gr cast HPs with 2205 in the Howa I had and it was complete garbage.
Velocity spread in excess of 50fps and groups were at best 3” at 100m.

I’m thinking of trying another 300blk and wondering if a Tikka build might be the better way to go than another Howa.
