About done trying to find a load

Provided that everything is tight and torqued correctly, try using a 160 and 175gr Sierra Gameking with at least 3 different powders, while ensuring that the thin barrel doesn’t get too warm.

If a rifle won’t shoot a Gameking, sell it.

I just got great accuracy with 150 game changers. Thoughts on the game changer?

I have the same rifle. Have you tried factory Barnes TTSX in 160g? Swift AFrame or Scirocco in factory ammo? Normally Tikka will shoot anything.

I have not just handshaking. Although today it shot 150 sierra game changers very good. Not sure if they are good enough for africa or not though

Personally for Africa I'd rather have a top quality bullet than the one that puts each and every shot in the same hole.
Personally I would be a no on GK.

I just ordered some 168 accubond lr. If the nosler doesn't give me what I'm looking for then I'll try another copper. The search continues! Thanks for everything Philip
 
I recommend 175 grain Nosler partitions or accubonds or 173 grain Norma oryx. They shoot very well in my pre-war Mauser 98 with a full length steel rib on a 26” barrel.

Someone mentioned action screws. Those have confounded me on more than one occasion, so torque those!

That being said, my .375 HH sheared the action screw off inside the action. I will have to have it drilled out. Is there a most common reason for this? I've never had it happen before. Thanks guys!

With that rig, I'd stray away from hot handloads (bbl too light-whipping/heating/warping) in a 7 mag case. What's the twist rate? bbl length? What COAL did you use? What's standard COAL vs. the mag length? Bullet seating depth is often the most critical detail, but many factory bbls are cut such that Std. COAL is close to the mark. Seating farther out/in often works better with certain bullets. What are you hunting? What range shots will you encounter? How much did the rifle cost? Do what was said above (how does it shoot factory premium ammo, and if good, what's its COAL?-duplicate It.) GL Typically with ultra-lightweight I back off on the case size and/or caliber a bit. The only ultralightweight mountain rifle I have in a mag caliber is a .264 (w/ a Lilja bbl and custom receiver) and everything else is in a (smaller) 06 or 757 case. All shoot mickey mouse groups using handloads and about 0.5" using premium factory when available. My son had similar issues with a 7 RSAUM in factory form...once corrected using magnaporting, HS precision stock (w/ some necessary relief for his particular bbl contours), timney trigger, and re-thinking handloads (hot was bad in that pencil bbl!) it also shoots m o u s e groups.

So......sell the damn thing. Right?
 
I'd second the multiple powders. Personally I'd pick the 3 bullets, that you would be most comfortable with and then go to work with a lot of different powders. Our 7mm mags all get best results out of IMR 4831, but at least 3 or 4 other powders that could give good results.
 
I would try some factory ammunition to establish a good baseline. The inexpensive Federal blue box ammo is generally very consistent and accurate in most rifles. It may not be the best for hunting but for shooting targets it’s a great place to start when establishing rifle accuracy. In general I consider that if my rifle won’t shoot the federal blue box with some reasonable accuracy then it probably won’t shoot anything well. As far as hand load development goes, and the cost of components, a chronograph is a good idea and will probably save money in the long run.

The most common reason for any screw to shear is that it was not tightened properly to begin with.

The TGK is a good bullet.
A bit tougher than the standard GK due to the thicker jacket.

One of my hunting buddies uses them in his 7mm RM for everything from springbok to eland. He does however avoid frontal shots on heavy game.
If the TGK gives good accuracy, the rifle should do well with Swift Scirocco’s.
Very similar bullet shape.

I bought a tikka 7 mag superlight last year and it's been very picky on bullets. I was hoping to take it on a cape plains hunt with Kudu being the biggest animal. I've loaded 130 barnes, 160 accubonds, 150 accubonds and 139 hornady soft point boatails ao far. It shot the 139 hornady the best by far. I'm going to try 150 grain sierra tippped gamekings next and I'm not sure if I'm going to try anything else with this gun. I'm either going to use the 139 hornady or buy a different rifle. The hornady is the only one giving me 1" moa. I've read the hornady bullets terminal performance on game is questionable then I've read that it will do just fine. Any thoughts on using the hornady on plains game? Thanks

@johnnybow
Some rifles is just plain fussy.
Have you tried different powders with each projectile as well as different seating depths.
Can be time consuming but will pay off.
Usually a 160 grainer and a healthy dose of H4831 or the next slowest powder will give outstanding results.
