I have one in 1-10 twist and having trouble with grouping from 100gr projectiles up to 120gr
Tried large number of various brands in this weigh range but no better, different powders,primers and still average
110gr@ 1'' TO 117-120GR @21/2'' TO 3'' , compared to cutting 5 holes to clover leaf with 100gr sierra matchking
Been told and read on many occasions that 1-10 won't stabilize projectiles over 105gr but when i bought the rifle gunsmith at the gunshop
maintained it would , maybe i should have stuck with getting a 1-9
although it does the job with 100gr i would like to have used 117gr for piece of mind on larger animals
Cheers

shat itself
Had all figures from swarovski ballistic calculator away i went 100gr matchking, 51gr 2209 and ''WOW'' finally my luck has changed
zero @ 200yds worked up to 407yds run out of paddock got about 3'' group at that , better than i expected after all the drma with the barrel twist rate
I am now a happy old vegemite

Im pretty sure my bad groups are all me. But... based on your comments that a 1:10 will struggle with projectiles over 100 gn maybe I should buy a couple of boxes of lighter projectiles just to see what happens.......
