I don't know where your information is coming from? Current Savage production has about the shortest lock time in the industry, AFAIK. It runs around 1.6 ms in the 10ML II, and more like 1.7 ms in the current 10/110's. My instruments show more like 1.8 ms to 1.9 ms on my 9 year-old pre-Accutrigger 10 FP, but that still beats the 2.9 ms on my Remington, which once was held to have the fastest commercial lock time. I don't know the age of your 110, but the fact the trigger is hard to lower the drop weight on indicates it also has the strong springs responsible for those short lock times in current production. The 110's were known for tight tolerances and if you get dirt in the firing pin tunnel or around the sear cocking indicator, you can get longer lock times. Another factor believed to contribute to that was sear drag. The trigger I suggested to you eliminates that.
Savage's reputation for best out-of-box production rifle accuracy is earned. The company is very accuracy conscious and keeps making improvements and has, in my opinion, done great service to the shooting sports by making F-class and Palma guns available that allow entry into those disciplines by many folks who were previously discouraged by cost.
As Kiwi98J posting on TheHighRoad in 2006 put it, when comparing purchasing a Savage to a Remington:
"Savage - Faster lock time, self centering bolthead, full contact locking lugs, adjustable headspace to my dies, button rifled barrel, recoil lug indexed to action and owner interchangeable barrels and boltheads. If Savage would improve chamber porting, machine the bolt raceways instead of broaching and lap the barrel, I'd truly be happy.
Remington - lipstick and rouge and another trip to the smith with a wad of cash to set headspace to my dies, center the bolthead, get full locking lug contact and change a barrel. But, man are they smooth and that hammer forged barrel doesn’t copper and my ‘smith loves me."
I expect I fall fairly solidly into the category of seasoned shooters at this point in my life, and I find the Savage quite satisfactory. I have to point out that lots of old Mausers and other guns are out there with long lock times that are still shot quite successfully on a regular basis. As with the internal hammer service rifles, which are not exactly lock time speed demons, the trick is to learn follow-through. I carried an M1A through Gunsite's 270 class and my pre-Accutrigger 10FP (still without the new trigger mechanism at the time) through their PR1 class and won the shoot off's at the ends of both classes, despite shooting against RWS and Sako and several other quality actions.
But if you still don't like the Savage design, for whatever reason, you're right not to spend money improving its potential. Timney and Jewel made there businesses on the fact the best possible trigger doesn't come from the factory on any production rifle. I don't see why the older Savages, in particular, would be any different in that regard? There is no free lunch.
