Thanks for all answers.
I have been using round balls and REALs on my rifles, but I would like to try a different ballistic.
Most boar hunting opportunities in Argentina involve waiting close to a water hole by night at moon light. Shooting under this conditions demand a 80-100 yards accuracy and trajectory, the use of scopes and also a good waterproofing.
Last year I made a scoped underhammer for this purpose but, as barrel is 1-48” it do not shot +240 gr .44 bullets very well. I would like to use my LBT like 300 gr bullets, so I need a 1-28” gun. I have to try hard RB to see accuracy.
I have the opportunity of buying a very low cost inline and I would like to try it. A 300gr bullet flying at 1500 fps looks very good.

Thanks for your advises.
