this is my first year with a sidelock and i have my .54 gpr shooting prb's and 90 gr of 2fg sighted off a rest dead center at 100 yds, i feel comfortable off a rest at 100 yrds. In the area where i hunt there is alot of open spaces so i will be looking at longer shots but have set my personal limit at 100. I have been doing alot of practicing off hand at 50 and 75 yrds. I might be able to hit an elephant at 100 yrds offhand lol.
