Ease of bolt lift after firing

[Larryh128]

Eliminate cock on opening?

It doesn't eliminate cock on opening, maybe not phased corrrectly but the ease of operation is unreal.

Thats how you run a bolt. You roll it open. Lift with a finger while putting thumb pressure down on the shroud. Thats how you dont rock a gun. Then pushing the bolt forward with his thumb. You want to push the bolt not the handle. The handle binds things up. Just as important, his eye stays in the scope and hes not blinking....... head doesnt come up every shot either. The biggest thing that helped me get real fast was not blinking. I always kept my head down and didnt look for the ammo but blinking when the shot broke cost me a split second. After training to keep my eye open during the shot I never have to find the scope or see if Im on the dot. I already know. That was huge for me.

I can promise you he could not have run mine like that! I will never be that good, I don't have that much time left on this earth to practice that much ;-) He is a master but I can try and I can still learn so when Jim gets my bolt back to me I'll be working on it!

Focus on being smooth. Speed will come with time. Smooth is fast.

Thank Mike, I have so much to learn, I'll keep trying!

You're shooting better than ever. Just keep it going and take baby steps forward without doing anything drastically different.

I have several bolt guns for target/competition shooting but none have as light a bolt lift as my TK2000.

I'm really anxious to get my bolt back from Jim and get my 6PPC going again!

Watching a video of someone running like 10 shots (posted here a couple of days ago) and noticed how easy it was to lift the bolt to eject the case. I've NEVER had anywhere close to that in Bordens, BATS and a Hall. I'm pretty sure the poundage of the spring on the firing pin might play a role but what else causes the heavy lift? A little insight to a trouble mind might ease the thoughts!
Thanks,

Depending on the number of times a piece of brass has been fired or the pressures that maybe to high to achieve your desired speed, the web of the case will swell. Recommendation since this will happen either sooner or later, depending on the above scenarios.
1) always full length resize.
2) when your start seeing click bolt lifts then use a small base resizing die on your a lot of brass. Redding is what I use because it’s what I have.
3) measure your shoulder to base after either set of process. Especially after using the small base dying which will cause your overall base to shoulder to increase between one and three thou.

Did you get your bolt back yet?

 

[Shooter13]

Did you get your bolt back yet?

It was supposed to be here Saturday 7/20 but they (UPS) said weather or emergency situation, so not sure when I'll get it!!!

 

[Shooter13]

Well an update! Got the bolt back today and got to try in my gun, OH MY! so much better than before, Jim Borden has incurred expense that he didn't have to but because he believes in his products so much he made it right. Bolt is slick and works terrific, thank you Jim Borden.

Was the problem attributed to Speedy mods to the firing pin or shroud?

According to Mr. Borden it was. According to Thomas it was not. All I know is it works now, beautifully! Made it a different gun. Hope to take it to the range tomorrow just to run it some and see how it does!!

A manufacturer like Borden who tries to put out the very best product, takes offense to someone modifying and "improving" their product. But on the other hand, they are in business because they improved others products.

What is the firing pin spring weight now?
