Remington 700 j lock experience needed

Need some help from some long timers.
I've got a 700 with the j-lock. I've worked on a plenty of 700s but this is my first j-lock I've laid hands on. It does have the snaked up firing pin spring in it and the firing pin itself looks different from the average 700 firing pin. I got inconsistent trigger pull weight with the original walker trigger so I put a timney on it. It is still more inconsistent than my other timneys. I haven't hand loaded for the rifle yet but I'm getting 100 fps plus ES with two different factory ammunitions. The first shot is the fastest along with the first trigger pull being the heaviest. Maybe just a coincidence but it has me wondering if this snaked up j lock firing pin spring has anything to do with it. I think I'm going to pull a regular 700 firing pin assembly out of my other 700 and see if it remedies the problem. Anyone else have experience with a j-lock?

Bolt lift upon recocking is also heavier than a standard 700. This is with an empty chamber.

Replace the Rem 700 firing pin assembly with a new one'..., none "J-lock", the assembly comes with none j-lock bolt shroud, something like $50, and forget about it. Mixing and match parts with j-lock I don't think works well from what I can remember??

I have 1 rifle that still has a j lock. The others I switched out for a GreTan striker assembly. I dont really notice the j lock that much. Its a 300 RUM without a brake so recoil is first on the list for that rifle.

I've read where several people didn't have any problems with the J-lock like yourself. I've heard a few others mention problems but didn't really elaborate on what the problems were.

I had a j-lock , replaced it with a gre-tan never looked back as mentioned above, still have it and the replacement pin shroud assembly works as advertised. In my opinion a replacement is the best way to go.

Did you have problems with the J-lock or just didn't like the looks of it?

Issues : previous owner locked it and lost key, I bought it and repourposed the action into a different caliber, and new rifle. Even if I had the key the spring binding issues reported with the J-lock would have me changing the assembly (the less that can go wrong, the less that will go wrong ) KISS especially in some of the places I have been.Cheap insurance was my thought.

I believe i replaced my pin/spring assembly with a PTG one, forget where I ordered the new shroud. Easy to replace and looks way better, and i have full confidence in it. Since then I replaced my spring with one of Tubb's springs, just for the hell of it since i'm not that good of a shot ;)
