Ok, so here is my quick theory on the perfect neck tension for the best accuracy out of a bolt gun. This is just my conclusion that I have come to over a few years of many rounds down range. I want to have minimum neck tension which means to me .001 neck tension if possible. Here are a...

OK, so my gunsmith says he has the action wrench for the Sako TRG-42 and the 338 Lapua reamers. I ordered a SS 1.250 straight Krieger barrel in a 10 twist. I'm assuming 1.250 is enough for the tendon but I'm thinking we will want to turn down the rest of the barrel. I'm afraid a straight 1.250...

BTW, I finally got around to addressing my FL Die issue. I desided to just take it up to my gunsmith instead of shipping it back to Redding. He took just .015 off the bottom of the die and it works perfect now. Can bump the shoulders back just enough.

Old45auto, Funny you mention using the Sinclair expander die and mandrel. I bought them originally for neck turning but just recently started using the expander mandrel on new brass and then just loaded them up. It provided perfect neck tension for my .308, .260AI, as well as my .338 Lapua...

Ok, so my next project is to re-barrel my 338 Lapua Sako TRG-42. I have one of the older ones with the 12 twist and want to rebarrel with a nice 10 twist match grade barrel. I've been looking at Krieger and Lilja barrels. I have a gun smith that will do the work, however he hasn't ever...

Taliv, I took 243 Lapua brass and necked up to 6.5 for my 260AI. As soon as I necked up, the donut started to form. I just expanded with the sinclair expander die and then FL sized with redding 260 AI die. Once fireformed, the donut was clearly visible. The trick was to take the fireformed...

I'm using .335 bushing for 308 Lapua brass that has been turned. Using a Redding bushing die to neck only. Very nice rounds with minimal neck tension.

OK, so I found a feeler gauge set at Sears for $6. I started with using a .005 feeler in between the shellholder and the head of the case. I full length resized and for the first time noticed that the case chambered a little easier. I moved to a .006 feeler and the case chambered nicely now. I...

fguffey, I hear you. When I said shim I really meant feeler gauge. I want to try putting the feeler gauge between the deck of the shell holder and head of the case just like you are describing. I really think this die is only .010 or so from bumping the shoulders back. Hopefully I can fit a...

Great feedback guys. I'm going to talk to Redding tomorrow and consider using shims. I will post the solution.

I have the diagram of the reamer that was used for my chamber. It has a 40 degree shoulder and so does the FL die so I'm good there. I'm really starting to think that the die is very close to the shoulders and the shellholder set may do the trick. I emailed Redding so lets see what they have...

So my shooting buddy just gave me a good suggestion. He pointed out that redding has a competition shell holder set that has five shellholders in varying heights with increments of .002". You can increase or decrease the case to chamber headspace without adjusting the dies. The idea being that...

Ok, this is my first post on this forum. I had a 260 Rem Ackley built a few months ago. The chamber was reamed using a Pacific Tool reamer and the description on the reamer diagram was "260 Rem Imp". I have been neck sizing only but after firing 5 times the brass chambers real tight now. So I...
