I beg to differ!
The stock Tikka Tactical in 300WM I have is a < 0.4 moa rifle at 1048 yards, that's a 4" 5 shot group, under ideal conditions. One time does not mean much
Another is a rebarreled - not stock T3, #5 Benchmark in 6 Dasher, this rifle is in the 5's but a recent bedding job puts in the 4's.
Again , another is a rebarreled - not stock T3, #6 Benchmark in 6 Dasher, this rifle is braked, McMillan A3-5 stock, it needs work as the last time out only printed a 9" 5 shot groupmat 1048yds.
The last one is a Tikka Varmint in 223, it will put 10 inside an inch at 100m and slam an MOA chunk of steel at 500m all day long as long as you are 'on' the wind.Sub MOA sure, sub 1/2 or .4MOA this is not
Impeccable handloads of BR quality surely helps as does bench technique and the ability to read the wind. You did not go out buy a stock Tikka and throw in some factory loads. You have also probably spent hours at the range and the reloading bench to do what you do - not to mention probably hundreds (if no thousands on reloading gear)
I have not had a Tikka , Sako or for that matter a Savage that would not put 5 in an inch at 100m.
Last year, and the year before that and the year before that, one competitor with a rebarreled - not stock Tikka in 6 Dasher never had a group larger than 1 moa, many groups in the 5" territory and one 3 shot group at 1.75", this at 1048 yards.
Accuracy and precision takes effort, time and education. The OP can be competitive, if that's what he's after , with a <$2k set up.
That is THE reality.
I do agree with much of what you are saying but CGN is so full of "snipers" it is stupid. A M700 SPS with a Huskemaw Super Duper Tactical Sniper Falcon Extreme Scope that shot a .6 group one time does not make it "sub moa" all day long.
The reality is that 90% of the "MOA all day long" shooters are either doing 3 round groups, calling their "fliers" or shooting one group a day and calling it quits.
But yes Tikkas for the most part will shoot better than Remingtons these day it seems.
