Yes, but. The gas system of the M1 is readily cleaned, including the port in the barrel. With a gas checked bullet, the hot gas can not contact the lead to vaporize it. The same holds true with the gas system of the M1A/M14. Not so much but doable with the M1 carbine and less so with the AR platforms. I don't think that was the reason, but I don't know, and so far I haven't found any reason not to. I'm still looking though.

I did get out briefly today. A lot warmer today. 32 while I was out. Cloudy. Rain is on the way. I took the scoped 45-70 High Wall that shot the 2.804 group. Same load. I fired four foulers, then switched targets and went after Rick. First shot printed about four inches lower than I expected. 2nd printed where I expected, which meant the group was already done. Continued to fire. Shots 3,4,5,and 6 were touching number 2. Shots 7,8, and 9 opened the core group to right at 2 inches. Shot 10 landed about 4 inches higher. To the burn barrel it went. It will be a couple of days before the weather will break. Time for a nap to get rested for a 900 bullseye match tonight.

We meet, shoot, then hit a pizza shop to discuss.

Capt Curl,
Regarding the Vin Mil rifles - the one with frosted bore.
Indeed, I had a Smith Corona 03A3 with frosted bore that shot cast bullets very well.

Here is a technique to polish that bore/any bore, including a substitute for traditional
shoot and clean process to break in new barrel:

Materials
1. Bore Snake of appropriate caliber
2. Turtle Wax Chrome Polish and Rust Remover- available at Fleet farm, and other automotive stores
Optional, but very helpful- a bore guide
Insert the lead end of the bore snake from breech thru to muzzle.
Apply a teaspoon of the Chrome Polish to the thick, "business end" of the bore snake
Draw the bore snake thru the barrel
Repeat 10 times
Apply another teaspoon of the Chrome Polish to the bore snake
Draw thru 10 times
Repeat up to 100 pull throughs
Now clean out the bore with patches, Hoppes,etc
I found this technique works very well on a couple of new barrels
as well as "less than perfect" bores
After doing this, so far the bores pick up less fouling, etc.
I believe the process helps to lay down and polish the fine grain of the steel
in the direction of travel thru the bore.

Oh, the Chrome Polish technique was introduced and advocated
more than once
on the Cast Bullet Assn forum by a guy out east
by forum name of Onondaga

Not sure if this is going to work or not, if not I'll email the picture to Semtav.

CPA 22 with 23 inch MVA scope, at 200 yards, same bench set up as last time,ammunition RWS R50, 10 shots.

Ok so it's too small to see so I'll delete it and send it to Brian. Dang.

Question:

T but what about a Winchester Mod. 52C? Just askin' . . .

Curl

that might be pushing the envelope a tad. Not that you cant shoot and post the results so we can see what it is capable of, but more on the lines of the hammered lever actions and pumps like the Win 62 or 1890 or copies of same

Semtav, please make a correction: My group with Federal Gold Medal Match measured 5.20". You have it listed as 5.00". It wasn't quite that good.

Thanks,

Just different ammo, with slightly better results on the horizontal, sure could use a spotter, lol.

Thanks

Now just have to give me the actual distance between the top and bottom hit for score Brian. ( should be slightly farther than 4.02) unless your vertical was that measurement.

[GrumpyBear]

Best I can measure Brian it's 4.1, but I thought we were scoring on the horizontal not the vertical, ?

[Aviator]

Hey Grumpy, I think the score is the measurement between the two farthest apart hole centers, in any direction.

[CptCurl]

beltfed,

Do you have any idea of what the chrome polish does to a frosted bore? Is the chrome polish abrasive? I wonder how it would do on a patch instead of a bore snake (I don't have a bore snake).

Thanks for the suggestion.

Now here's a question for anybody with an answer:

To shoot in my .303 and 7.65mm rifles I bought a Lyman #314299 mould: https://www.midwayusa.com/product/1010237938?pid=530266
I haven't cast any bullets with it yet. Does anybody know which size gas checks it takes?

I bought a pack of Hornady .32/8mm gas checks, but in the back of my mind I'm thinking they are going to be too big. I haven't seen gas checks offered in the .313 size.

This bullet will get me shooting lead in the many .303 and 7.65mm rifles I have lying around - particularly a splendid Fraser Single Shot rifle (that's what I bought the mould for).

Show us some more pics of that rifle.

PS: I got your PM, but have to run out of the house for a couple of hours. I'll get with you when I return or you can call me after 0830 as I'll be sitting in the waiting area at the auto shop.

The Chrome Polish does have an extremely fine abrasive so as to polish surfaces
It is a bit more aggressive than the J-B bore cleaning paste, which also contains
abrasive. The idea on the frosted bore is to smooth out the frost in the direction
of bullet travel towards the muzzle.
Using patches rather than a bore snake should work, but would take "forever" to accomplish
what the Bore Snake can do in 100 pulls.
Bore Snake is a small investment and it will last thru a lot of bore polishing and other regular cleaning,too.

Re. Gas Checks on the 314299: The 314299 is simply a copy of the OLD 311299 that was up to that size as cast.
My old single cavity311299 casts a bullet at .313-.314. 30 cal Hornady gas checks fit just fine. My more recent
(plastic box) two cavity 311299 casts at 0.310-.311 in the same alloy. I size the bullets to 0.311 for my Springfields
and 1917 Enfield.

I expect the gas check shank of the 314299 should be the same diameter as the 311299s, both old and recent.
SO,314299 Should take the std 30 cal gas checks. they start out large and
your sizing to 314 or so for the 303Brit should work just fine to crimp on the checks.
I am sizing my 311299 bullets to .311, no problem.
Yes, the 8mm gas checks are sized for .323 or larger bullets and they will not crimp on to the 314299 bullets,
at least, not without a "struggle" for your sizer/luber. I just tried it....

Arnie, why not real fine fire lapping? Or even fire lap with the chrome polish?
