Wondering if anyone could help me in getting my Tikka T3 Lite chambered in 270 WSM to shoot 1 MOA or better. When shooting factory ammo - Winchester Ballistic Silvertip 130gr and the reloads I have worked up (data listed below) the gun shoots consistently around 1 ¾ - 2” MOA.
One thing I noticed is that you have to clean this rifle after every range session at around 25-30 rounds as you will see a lot of excessive copper fouling in the bore and the groups will really start to open up. Maybe this is conducive of 270 WSM’s in general I don’t know. My buddy has a Winchester Model 70 Super Shadow and with his gun shooting the same reloads it will shoot ¾” MOA at 100yards all day long and does not produce the fouling I see in mine. Different guns I know. One of the issues I have had with this gun is that it seems to have an excessively long throat, i.e. I can seat the bullet well past the allowable magazine length in order to get 0.010 off the lands.
Maybe I am asking for too much but I would think at 100yrds this gun should be able to shoot under 1” MOA?
Another thread here on the fourm similar issues but no real resolution- Tikka T3 problems
Here is what I am running right now:
Approximate round count 200-250 down the pipe. Rifle was bought new in 2008 shot occasionally here and there with 3-4 years with zero rounds down range due to deployments.
Rifle – Tikka T3 Lite
Caliber – 270 WSM
Barrel Length – 24.37”
Barrel Twist Rate – 1:10"
Scope – Leupold VX-2 6-18x40mm Adj Obj Riflescope, CDS, Fine Duplex Reticle (It’s a scope I had lying around so I decided to throw it on to trying and alleviate a lot of me in the accuracy testing process; way to much magnification for a hunting rig)
Mount – DNZ Game Reaper One Piece Medium Mount
Rifle stock screws (Front/Rear) troq'ed to 35-40 in lbs as per manufacture recomendations. Scope rings properly torq'ed as well.
** Reloading data is from the Hornady 6th edition book **
(Min Charge – 52.8 2800 fps – Max Charge –60.0 gr 3100 fps; I don’t own a chronograph so I don’t know exactly what the true velocity is)
Current Reload Data:
Bullet – Hornady 130 gr SST
Powder – IMR 4350 57 gr
Primer – WIN WLRM
COL: 2.824”
Currently I have zero pressure signs other than the copper fowling. My next step is to start from the bottom say 53 grains and work up in 5 grain increments shooting 3 round groups at 100yards and see what happens on paper. I may very well have to swap powder / bullet combos but would like to see if I can get my current reloading supplies to work out.
Any assistance would be greatly appreciated,
