Toying with another build, maybe something which will make the spinning Ferris Wheel at JG's go all the way over. My 77gr .223 was the little train that couldn't.

Looking at a 6.5 creed, baby sister to my 6.5 Weatherby, or maybe a 7mm-08 since I'm already set up to load it.

Anyway Academy runs the cheapy Rem 700 on sale, which caliber should I get to build on?

Trying to stay kinda on a budget. I'm going to gather parts and dump them in Trigger Times lap for the build, I didn't know he was building guns full time now.

243, 308, or 7-08---- short

With 7-08 you never know you may get a shooter right out of the box


Donate to TX Youth hunting program.... better to donate then to waste it in taxes

He's not building guns full time.

It doesn't matter what the rifle is that is the donor action. 243, 7-08, 308, ect. As long as it is a short action with a .308 bolt face. 6.5 Creed or 7-08 both would be very nice.

if you just want the action, why not find a K98 and built off that? Certainly it can be found cheaper

I like the long action better. I tried to first build a Savage 7mmo8 short action and found that my reloads would not fit in the internal mag. Then I used a long action 110 and re-barreled for the same caliber and did not have any more problems. If you are not reloading then you will probably not have any issues but you try to get a precise OAL then go long action.

The 7-08 barrel I have, Tony chambered, and it is on a short action. Seating 162 A-maxes even with the lands I still have a looooong ways to not fit in the mag. So it depends on who does the chambering.

Agreed...freebore controls all of that.

On the subject, will a 105 gr 6mm fit in a standard factory tikka mag?

And that is as long as you do not use an external mag like with my new build. My reloads will not fit in a 308 AI mag so I needed to use a long action with a 300 win mag / mag.

Write down the length of case head to ogive. Then seat the bullets just long enough your ammo will fit in the mag. Then you will know how far they are jumping to lands. My 6.5 Creedmoor was chambered with a reamer that had done several barrels. My 140 A-maxes are jumping .024" No big deal, I seated them to fit the mag then went about powder testing.

Same thing, seat the bullet so that the whole cartridge will fit in the mag.

I take it you're asking if one could reach the lands inside mag length with a tikka standard 243 mag running 105 amax bullets. My Tikka T3 lite 243 mag measures 2.83" I've never checked OAL with 105's to touch lands in that Tikka because it has 10 twist factory tube that wouldn't stabilize them, but I suspect I wouldn't get to the lands within mag length.

I do shoot 105 amax in my re-barreled M700 243, 105's touch the lands at 2.875", which fits within the BDL mag box that measures 2.9" or so. But I wouldn't get close within the Tikka mag at that OAL.

So it does depend on how much freebore the smith used when chambering the barrel.

If I seated the bullet in the case 80 thousandths or more farther into the case, it would fit the 308 external mag barely. So the bullets were originally seated 20 thousandths from the lands so that would make it 100 thousandths jump to work with the external mag. This is with Nosler Hunting ballistic tips 140 grain.

See if I can't do a better job explaining, freebore is the space between the end of the chamber and where the rifling starts.

So in your example GLC, if you took .100 off your freebore you would be touching the lands where you are seated right now.

People play with freebore to get the bullet to sit in the neck where they want and another reason to change freebore would be for use of mags. I don't know what my freebore is in my 6slr but if I seat the bullets right at mag length I'm jamming them...so the freebore is pretty short on it.

Now, to take this one step further...depending on the bullet design will change everything so you can have a chamber done for one bullet and you swap designs and you have to start over. An example, a 105 hybrid is longer than a 108 boat tail...so while I said above I can load the hybrids at mag length and actually be jamming I might try a 108 or an amax and not be able to touch and stay within mag length.

Does that make more sense?

Also, I have known guys who order their reamer with 0 freebore then use a throater to get the freebore exactly where they want it. It gives them some flexibility and they don't have to order 6 different reamers to get different freebores.

Aren't custom rifle stuff fun? wink

If you want to spin the ferris wheel, why not a 338LP? I know JG likes rifles that blaze over 3100fps... Something about he likes to fix his equipment peep

With the T3, I believe you can change out to the long action bolt stop and swap to a long action magazine, OAL problem solved.

Then again, there could possibly be feed issues there... scratch

Disappointed in the 3/8" AR 500 for those close targets. I'm gonna recut some new bolt holes but I will be replacing them with 1/2" AR 500. Everything inside 500 yards.
