I thought I'd post this over here also.

All this talk about the 10.75x68 has reinfected me about building one!

I thought I'd use this post to hopefully start a knowlage base of 10.75x68 info.

I have a 1940 mfg FN Mil style action that Steve Button
has stoned & polished, put a new bolt handle on, contoured
a SMP M1 (30-06 5 down) bottom metal, it is intended to
look somewhat Rigby like.

Put a Hubber Concepts 2 stage adjustable trigger on it.

Didn't surface grind it, all hand stoning, as I wanted to keep
the charger hump & use stripper clips (modified).

This will be an open sight rifle only.
1 standing & 2 folding with a Lyman M48 peep sight.

Steve worked the front sight to sit lower to bore &
will do same for rear sight. Since it is an open sight
rifle only, it also has more of a Pre-War look with lower
sights. We might have to cut off rear standing sight if
it gets in the way of peep sight view. We'll decide when it's
finished.

Steve took an NECG H&H flip night sight & removed the barrel band
compleaty recontoured it. Making it more Pre-War looking I think.

Since I have this as a starting point...

What the heck, let's build a 10.75x68!

I'm sending Steve 4 dummy rounds to verify
that it will hold 4 down & 1 in chamber.
We are sure it will but just making sure!

With this mag box I can load to 3.35 COL or there
abouts. So can seat a Woodleigh 400gn to crimp in
the cannelure.

Dave Kiff sent me 3 reamer drawings, CIP, a US version
& a cast bullet version.

Just got them, plus they look really confusing to me!

I think I want the CIP version throated for the longer COL.

Getting a LW # 5130 Type E barrel. Ordering it in the standard
Contour ie.. not changing the contour, at 26".

It is .625 at 26" & Woody said it going up about .012 per inch
if shortening the barrel.

I will go with 24" or 25" finished barrel.

I like longer barrels usually but 24" may look better for this rifle.

Decided to have Steve make a solder on under barrel sling base
with the large eye like some of the earlier Rigby's.

What I want this rifle to be a general purpose gun, 200 yd or less open sights.
So not wanting to race with a 404J. Aming for 8.5 lbs. will add wt if needed.

If it can go up to 2210-30 FPS that's sweet, if not, 2150 plus is also good.
I'm sure it will go fast enough to get the job done as long as I do my part.

If this posts a bit jumbled its because I had to use my iPhone
to post. Computer is in shop.

If anyone has load data, articles, pics, info or such lets share them.
I have some load data I've collected & 2 articles.

I'll post pics of the action & front sight as soon as Steve sends them
to me. I lost the first one he sent me Duh!

Info on reamers & go- no-go gages would be helpful.
I may just buy a reamer & gages from Pacfic if needbe.
About $200 for a set unless there is options.

Cheers, Allen
