Recently, developing loads, my Savage 340 18.5" barrel, 30-30 was shooting a Ranchdog GC PC boolit (167.0g wt) 2" low at 50 yds. The load was a 23g H4895 with good accuracy. I purposely made no scope adjustments.
A day or so later I was shooting the same rifle using a 311041 GC Lubed boolit (181.3g wt) 6.5" low at 50 yds. The load was 34.5g Leverevolution with very good accuracy. Again no scope adjustments were made.
The loads were not chrony'ed.
Unfortunately I do not have any RD's loaded to recheck the earlier 2" low finding to determine if its a scope issue. The scope, btw is a Weaver Classic Extreme 1.5x4.5x24.
My question, if you will indulge this cast shooting rookie, will shooting a 14.3g heavier boolit likely to cause a drop difference of 4.5" over the same distance?
Thank you
