85-87gn our of a 1:10 243 win. T3 varmint. Anyone lucky??

Not sure if you have tried bypassing 100 yard testing all together? I have a remington 700 in 243 with the 1:9.25 twist. It has drove me crazy trying to find loads with heavier bullets. Couldn't even get 87 grain vmax to group at 100. Then i found a couple loads that showed promise, around 1" at 100. I shot those same rounds that drove me crazy and to my surprise, my 1" at 100 was now 1/2" at 200. I have since given up on 100 yard development. YMMV

Physics says that bullets don’t start steering themselves back into good groups. Parallax issues are the most likely cause of the phenomenon described.

So a load that groups better farther out is strictly a parallax issue? Not sure about that one. Makes sense that ladder testing is recommended at 300 yards.

Not necessarily, I said parallax was the most “likely” cause. Some days the wind blows them into the group:). Most shooters do not read wind well enough to make much sense of a ladder test at 300yds
 
1/4 moa you might want to rebarrel with a Benchmark 1:7.7 twist and shoot a 105gr Berger Hybrid. Restock it or put it in a chassis. Take some LR shooting courses too. Will be a hell of a journey

Ladder testing is done at 300+ because the differences between loads are more noticeable, at 100yds the difference in impact from step to step is too small.
 
Ok, maybe you can disregard the 1/4’’ goal.

I don’t want a 20lb rifle with a 10lb front rest and shoot it from a gun vise...

My goal is to have a «#long range hunting#» rifle type, capable of shooting plates at long distances.

I can tune the rifle with bedding or changing the stock, but I will not invest more than the gun value (if so I would have picked a TRG or a chassis type rifle). I want a rifle that still looks like a varmint rifle (sleeper..!)


Thanks for all the advices and answers
 
Is the t3 your shooting in the Tupperware stock? I can show pics of unreal groups I got with mine, trick was I bottomed out the trigger pull, gouged out the stock so it it wouldn't contact the barrel when using a bipod and made sure the bolts holding down the receiver were torqued accurately .

Tikka’s are good guns some are capable of 1/4 moa and others not. I’ve had two 7 rem mags one I couldn’t get below 1/2” at 100 and the other is a laser and regularly shoots 1/4” if I do my part. This rifle is stock except for trigger spring. No modifications to the stock I only torqued it back to 40 in lbs and called it good.

I am still working with my COAL on my Rem VLS 243 using 87 Grs V-Max with IMR 4064. I am getting between 0.6- 0.7" at a 100. I bought some Federal blue box 80 grs factory loads and got between 0.45-0.55" at 100 yds. Maybe something to try.
