Scope reconditioning

I have an old Springfield Armory scope that is near and dear to me. It functions just fine (less the lighted reticle which is inoperative). But it needs a cosmetic makeover. Made in Japan and I really don’t want to send it overseas and there is no stateside service facility that I can find. Any recommendations of someone who can help me? I’d prefer someone known to you as reputable. TIA.

34mm rings for a pre-1964 Winchester Model 70 (30-06)

As titled - Talley makes a set for Winchester 70s generally but it would be great to get a set with a 20moa cant if anyone knows of an alternative!

A pic rail is off the table for aesthetic reasons, but if there's a dovetail that passes the owner's standards for appearance that would be a great rec too.

Thanks for any help in advance!

Rifle Twist Selection

In previous posts I mentioned that I have four Remington 40 X rifles and that I was that having the barrels changed Due to the twist. The current twist is 14 which limits you to light weight bullets. The calibers are 222 Remington 223 Remington 243 Winchester and 7mm Remington Magnum.

The first two I asked the gunsmith to make the twist 7.

The second two since I was changing the barrels, I decided to have the caliber changed. The 222 Remington I am stuck deciding between 6.5X47 Lapua and 6.5 PCR. The 7 mm Remington I plan to have it converted to 300 PCR for these two I am thinking that a 9 twist would be adequate.

So: I have two questions the first is does anyone have an opinion t=at to my choice of twist’s. The second question relates primary to the 222 Remington conversion to a 6.5 mm; In my situation which caliber would you chose?

300 blk 180 grain bullet loads?

Does anybody know if its possible to create a load in 300 blk with a 180 grain bullet? Specifically the hornady softpoint flat bottoms. I have a bunch of these bullets for 308 hunting, but I was thinking I might be able to put them through the blackout. I have cfe blk and 1680 and a 10.5 in barrel to run this all through.
If anybody's done this before that would be helpful, especially if you have a load that works and won't blow up the gun or cause squibs.

Short 308win barrel twist rate for subs/why no fast twist 308 barrels?

Which twist for short barrel 308 running subs and supers (basically like a 300blk)

Been looking at getting a short 308 barrel for a little while with the hopes of running subsonics for plinking/fun/limited hunting, but still shoot supers.
Looking at posts on here and playing with the Berger stability calculator, it seems like a standard 1:10/11/12 twist barrel are capable of handling subsonics, the 1:10 being the best candidate but all able to do it if you choose the right projectile.

However, I can't help but wonder why 1:8 twist barrels for 308win aren't a thing, especially shorter barrels.
1:8 is more or less than standard twist of 300 Norma, so there is obviously no risk in a short barrel 308 over spinning bullets.
Running the numbers on a 110gr bullets @ 3000fps in a 1:8, the RPMs are 270,000 which is getting up there but still comfortably under the 300k magic number.

If I'm going to get a 16-1" barrel spun up and want the most versatile twist possible, what should I go for? Stick with a more standard 1:10, or go faster to a 8 or 9 twist?
I'm dream (probably a pipe dream) would be able to comfortably run subsonics, 125gr TMKs and 168-175gr SMK/TMKs.

What about FN .264 LICC?

Don't know how I missed this at SHOT Show 2023, but somebody posted about FN's new .264 LICC and after looking into it, it seems pretty cool.

The .264 LICC (Lightweight Intermediate Caliber Cartridge) is based on the .264 USA, which is a 6.5x48 cartridge developed by the AMU (Army Marksmanship Unit) with a case head of .441, like the 6.5 Grendel; it’s basically a stretched Grendel. A head diameter of .441, like the 6.5 Grendel, 6mmARC, and .264 USA, is the largest that can reliably double-stack within the dimensions of the AR15 magazine well. If you move up to .473 you can’t double-stack in the AR15; you need a redesigned magazine (especially if using polymer mags) and mag well.

FN's .264 LICC (6.5x43 with a 2.5” COAL) has a case head of .473, like the .308 Winchester family of cartridges, as well as the newer 6mm GT. The 6mm GT has a case length of 44mm (1.73"), and a 24" bbl velocity of 3075 fps with a 110gr bullet at 62,100 psi pressure, according to Hodgdon’s reloading data.

FN has not released specs on the .264 LICC, but a 6.5x43 with a 110gr in a 24" bbl should get 3100 fps (add 25 fps for the increased surface area “piston effect”), and a more optimum weighted 115gr should get 3050 fps. Pressures should be around 62k psi, much better than the 80k psi of the dead-end 6.8 NGSW.

Note: 62k psi is still gonna kick too much for the average troop, so a recoil-reducing mechanism like “constant recoil” is a must.

A 6.5mm 115gr hybrd OTM using existing Berger ogives can have a G1 BC of .610. Using the 25 fps per barrel inch rule of thumb starting with a 24” bbl at 3050 fps, a 20” bbl would get 2950, a 16” gets 2850, and a 12” gets 2750.

Ballistics could be pretty good in a compact package no bigger than an AR15, which the Ruger SFAR has proven possible. Cases are two-part and made of stainless steel and are 20% lighter than comparable brass. More compact cartridges like this help maximize the soldier’s basic load over the 6.8 NGSW. Gets 25 rounds in the same length as a 5.56 30-round mag.

Is FN on to something, or not?

Rifle Scopes NX8 4-32X50 vs LRP S3 4-25X50.

Looking for a compact option for my Sig Cross STX (6.5 Creed) . Its a pack gun (gunslinger 2) . Only looking at the XT-MIL and the ZF-MRi versions of these:

LRP S3 4-24X50.
NX8 4-32X50 F1

Are there any standout reasons to not get one over the other ?

( Looking at the newest NX8 version out there to avoid the early reported eyebox issues.)

For hunting ( coyote and white tail ) and occasional steel out to 1k max.



Thanks for any reply.

The 7mm-300WSM Improved utilizes a 45° shoulder based off the 300WSM and 270WSM, which is shorter than the standard 7WSM. The benefits are a longer neck to support the longer heavier bullets and availability of good quality Norma and ADG brass, which the plain 7WSM does not have.
I make my cases out of 270WSM Norma. It doesn't get any easier, simply take the 270WSM case and run it through a 7mm expander mandrel (included). Then prime the case and fill it with the preferred powder for the bullet weight (N560 for the 175 grain Berger, H1000 for the 180)
