Thread: Tikka 223 not grouping after shortening

It most likely will be just the crown shortening the barrel willnot affect accuracy if done properly
Buy a Competent Machinist
Theres a few guys of here that have very old school 1950’s thorghts on here almost like it was what there grandpa told them its 2019 guys a lot of what was thought to be true in the older days has ether been proven untrue ot been invaded by modern technology a lot of this is to do with barrel lengths and or shortened barrel and it’s simplyNot true in this day and age
Every single centerfire rifle I have owned in the last 10 years have been shortened to 18-20” with no ill affect my creedmoor shortened from 24 to 20” will shoot 0.25” groups at 100 and I have mates with barrels as short as 13 or 14in barrels that are shooting sub moa at 100 yards and much farther

Now to fix your problem simply get a Confident gunsmith to recrown the rifle
Its a possibility that the Machinist that’s done the work has had his tooling slip in the barrel and fucked the last little bit of rifleing so he may need to trim another trim another 1/4-1/2” off to get rid of the damaged peice of barrel
But then you’ll be back in Business

The only negative effect of a Properly shortened barrel is the loss of a little speed normally arround 25-50fps per inch you shorten
