Powder Compression

[Klaus]

Last Saturday i went to my Range and try to get some successful shots with Rought and Ready Rear and Penny Front



Weather was Cloudy and a bit Rainy , Temperature 20 C / 68F
Distance : 100m
10 Shots/ Blowtubing after each shot
My first Load :
68 grs KIK FFFg / 0.2 Compression / Milkcarton
OFW / Coffeefilter
Large Pistol Primers
.520grs Gov.Bullet
Targetpicture / Bucket measured 16,5 cm x 12 cm / 6.5 by 4.72 inch
Lube: Emmerts




Second Load
5 Shots/ Blowtubing after each shot
63 grs.KIK FFFg/0.05 Compression/ Milkcarton
Large Pistol Primers
.520 Gov Bullet
Targetpictures / Bucket measured 6x5 cm /2.36 by 1.97 inch




for me it appears that a minor powder charge or coarser powder kernel like FG Grade with less velocity are more accurate than FFFG in my Rifle on given 100 Distance.

Example :




Maybe this results will change dramatically on longer ranges ?

has anyone here made ​​of similar experiences
