new internals? help consistancy?

[IMPossible1548]

ok im planning on getting a ND equalizer, ND ti pull pin, ND slick shot, and a rat hole brass hammer. would these be a good balance of internals? it would be about 1200 grams which is what FOM reccomends. would this setup help my consistancy? what would it do?

thanks

i thought FOM recommended 1200 grains not1100

[thebluenu]

yes its recommended that 1200 grains is used, but well, you cant be exact.......

oops i got messed up because he said no lower than 1100 anyways... my internals are about 1200 not 1100

[Awhislyle]

well all delrin bolts give better consistancy

ok well what would i benefit from balancing my internals at 1200 grams

[big ugly spyder]

yes you would its not too heavy or too light when its heavy the gun neds to work harder, when its light it gets sloppy.

While I'm one that is big on "theory", I realy didn't have the knowlage to work out the "best" weight for a hammer. This let to good old fasion testing.

Basicly we tried a couple of differt combinations of interals and then started swaping out hammers. While it will vary from gun to gun, we started with a Rat (what else) with the "stock" set up (vooDoo bolt) We chopped up a bunch of hammers to get differnt weight ranges. Then we set the gun up too shoot "rignt" at 280/180 We shot over a chrno to see what happened to the veloicity. We quickly found the point where we got got the combination of best veloicity and best consistencty.

As a test, we when back to the orginl "stock" hammer to proof the data. Having a basic weight in hand, we tried smaller changes to see if we could "fine tune" it a bit.

Now please relize that this is not "exact" simply because you are dealing with advrage veloicities and we simply didn't make an "adjustable weight" hammer- we just took hammers and cut more or less off them.

The end result was the brass Rat hole hammer. We tried this hammer assembly in a number of other guns, and the preformance was simular to what we got with the orginal Rat.

The second biggest group of guns we send out have LPRs An ND Slick shafts. While the Brass Rat hole worked fine, we found that we could go even lighter (without losing preformance) to balance the extra weight of the ND shaft and MAYBE because of the higher valve pressure of the LPR set up.

At any rate we came up with the lighter SS Rat hole for use with the ND shaft.

The holes where mostly just a way of reducing weight without having to re set up in the lathe. ( I can do holes just fine on the mill thank you) At anyrate, the hammers with holes SEEMED to have a snappier movement. I have no way to measure this- and I gues it realy dosn't matter even if I could because the only test insterment we are using is the chrno- so the results on the chrno are what we are conserned with.

Thats a very long way of saying the Brass Rat hole is designed for the stock shaft and the SS rat hole hammers is designed for the the Slick shaft.

I have a customer that went to the extreame of the Demonic hollow ram, the new super light Ti pin, and cut the back half of his ND bolt off to make a realy light set up. He claims that the SS rat hole works perfect for him, but I honestly don'r know if he tried heavier hammers of not.

ok so i should get the SS rat hole then. but my weight will be 1100 grams so is that ok? btw i would have an ISO mod hooked up to this
