oakdale ca,
Can you still purchase his aftermarket bolts for Remington 700? I looked online and all I can find says no longer available. Does anyone know if he still makes them? Or where to purchase one?. Or any other suggestions would be great
 
I have a ptg bolt in my 243 ai and i like it so far, not really a fan of the m 16 extractor though. I like the tubb bolt because all of the mods he does to them. Well I'll probably go with ptg if I can't get a hold of him.
 
The benchrest guys have proven the speedlock firing pin assemblies are not as accurate. They speed up lock time for offhand shooting but you loose accuracy off the bench. I bet the Kiff bolts are trued and just as good. Probably where Tubbs buys his. Matt

I'm curious since I was considering buying that set up, upon what is the claim they are less accurate is based?

Its a spec firing pin with a faster spring so I'm having a hard time imagining how it affects accuracy negatively.
 
I believe the pin is a lot lighter and the hit on the primer is inconsistent. It gives more inconsistent ignition. It is more prevalent at long range, but shows up at short range like in the PPC game. It has been proven when you took an accurate benchrest rifle and changed pins it shot worse and was never able to be tuned as good again. I know one guy had a good shooting heavy gun for 1000 BR and he told me his gun stopped shooting good since last year. I asked him what he changed and he said nothing. Then he said he bought a speedlock firing pin and I told him to put the old one back in. When he did the accuracy returned. I also saw more then one gun do it. That is why The gunsmiths like Dwight Scott and Dave Bruno do the altering of BAT actions. Dwight Scott told Bat his ignition was no good and showed him why. The new Bats come with a new heavier firing pin and different spring. There is also a new assembly available. If you shoot offhand you will not notice it but a great shooting rifle on the bench will show it. If you don't believe this go to 6BR Forums and ask this question. A lot of the benchrest and accuracy guys hang out there. Matt

Hmm, interesting. I didn't realize the had a lighter firing pin, I thought the major difference was a heavier spring. Are they perhaps a bit smaller diameter? That would certainly create an issue with essentially random strikes instead of consistently hitting the center of the primer.
 
I believe the replacements for like a Remington is made out of aluminum or titanium. They are definitely lighter. Another thing to think about if the time of firing is 2.5 to 3 milliseconds and you improve the time 25 percent; how much are you gaining? My numbers are not exactly right but I think they are close. Not enough that you are going to tell. I remember reading a piece on the lightweight pins but can't remember the exact numbers. I do know from personal experience they hurt accuracy on a BR gun. I have heard of a bunch of them breaking especially when dry firing. That would be a good way to ruin a hunt. There were various threads on 6 BR over the last year or so talking about tem. I also believe I remember reading where they have a certain lifespan before they break. Some things are made to catch shooters and sell products. They sure can make it sound good. Matt

Yep, titanium has advantages but it has disadvantages as well. One of which is it is more brittle than stainless or tempered steel.

I would never want an aluminum FP for the opposite reason, it is too soft.
