all the David Tubs do was change the harmonics in the barrel and change my aim point and the bolt shroud does not bounce around when you pull the trigger.hothead said:are you saying that changing the firing pin spring made that big
a difference in your zero ? If so , I'd go back to a Remington spring ..

Can not wait to shoot rifle and the new scope. Mine has DDR ret. Looks like your new rifle shoots well, good luck with it. The way my luck is going with my new build I may die of old age or an anxiety attack before I get to shoot it .
Erik I shot 3 round groups at 100 yards from 42gn to 44.5gn in .5gn steeps. The 43gn and 43.5 was the tightest group then I went 43gn to 43.6 at .1gn steeps the 43.3, 43.4, 43.5 all the bullet holes were touching jut the 43.4 was the tightest. I will try 5 shoot groups at 300 yards with 43gn to 44gn in .2gn steeps and see how that works. Thanks for the advice.Erik Cortina said:willbas said:I could not get out to my 300 yard range raining which we need but I went in doors and did some fine tuning on loads I had be using 43.5 gn of IMR 4320 today I found out by dropping just .1 gn to 43.4 I shoot my tightest three shoot group yet.
If .1 gr makes that big of a difference, you must not be in the middle of a node. Do a detailed load work up to find your node and load to the middle of the node.
Know your node!
