Gas Checks May Soon Be Only a Memory

Many of my loads are in the rough area of the 32-40 of MANY years ago.
So, I guess in a way we are going back to the " old ways."

I refused to use gas checks at all until I got a gas gun that I couldn't just soak the parts overnight in . Shooting good groups at high-speed was a cinch and half the time of paper patch.
I guess maybe I came the long way around fussing with PB and PP but the trip has been worth it .
Nearly every NOE I have is a 2+2 except those that will likely never be needed or wanted specifically 1 way or the other . No need for a GC in 9/38/357 , wouldn't want a PB in the gas guns .

Just over thinking the drop right now....I'm getting about 5 to 5.5" difference in my gas checked vs PB @100 yds...don't know if I have to double that for 200 or what

Input your variables and guess no more...

Even works on a phone.

My 3030 150 6tg loads with a 50yd sight in drop 7 feet at 200yd. Roughly 38spcl ballistics. Surprisingly my scope doesn't run out of hair till 9' at 200.

Hey Free b...:)))...Thanks..that program fills in all the blanks on my drop tables..I have several for Lyman bullets...but could only make an educated guess with the NOE designs..
Nothing like going to the range with a plan...Thanks again..Dan S.

PS... my scopes are shimmed for an extra 20 MOA..not much if I find a need for 7'..but at least I have that much...I'll just set the target higher and the paper lower..used to shoot my Savage 99B .303 @ 500 with cast.. and a Lyman Tang sight ..guess I can get something on paper....

:) happy to share. Hope it helps remove guess work.

@ 500 with cast.. and a Lyman Tang sight ..

Very impressive. I'm trying with open sights but, haven't made much headway. To easy these days to slap a scope on there & see better.:oops:

With 7' drop and no horizontal aimpoint in the scope it's still a challenge. I kept 2 of 3 on target the first try. Practice far off makes shooting close easier.

It certainly does...before it got so developed around here most of our shooting was 250 + yds...shooting over cranberry bogs...

500 yds ..shooting at 16 inch balloons is not all that much of a challenge
.especially when they wooble back and forth ..it gives you about a 30 inch target ..you got a 50/50 chance on being off on the same side the Ballon moves to when the bullet gets there....I got three out of three before it was pointed out to me they weren't my ballons..

Plus consider the sight radius...26"barrel plus receiver...got to be 30+ inches...

Just thought I would see if I could transfer this from Photo Bucket... Well I guess that worked
Winchester Model 54 30-30 100 yds...I beleve you all have seen this

Wow, I only get about 14" drop at 200 with a 100-yard zero using the Lee 309-230-5R (aka ICBM). I don't know what the BC is but it's a spire point boat tail so it's bound to be at the top end of the spectrum.

My charts are showing an additional 19" for something similar to the 30H @ 1500 or so..at least the number of clicks are cut in half for 200..
If I remember the program said 25" +/- @ 1200-1300 fps..still a lot of clicks....might be better off with iron sights...either way fun-n-n-n...

Dang...now I can't wait to try this....:):):)

That was at 1040 fps, through a silencer. My baffle clip design tends to shift the POI a couple MOA, so I orient the clips so that the shift is in the up direction, which probably sends the bullet downrange a little more in the point-up orientation than an unsuppressed rifle would.

I am thinking that .688 is very optimistic, like Nosler B.C. optimistic, when I designed the 230-300 blk it was almost identical except the boat tail. Mine only has an estimated b.c. of .540

I wouldn't argue lee's #'s being off. They have a track record.


I got three out of three before it was pointed out to me they weren't my ballons..

Hilarious! Plead the fifth, admit to nothing;) seek council if questions arise.

Commandeering targets is serious :D

That reminds me of a time I was shooting at my local 100 yard public rifle range and a father/son duo showed up with slug guns and posted some of the self-defense silhouette targets up. After both of them blazed through probably 10-15 rounds a piece and hit everywhere BUT the silhouette, I swung over and put one .30 caliber cast bullet dead center of the forehead just to be a wiseguy. They actually did notice it when we all walked down to change targets, and we all had a laugh.

The best thing I ever did, was once we had a BBQ after work when I was working at a welding shop. I didn't get the memo that we were getting together to shoot as well. After dinner the guys get there guns out and my boss points out about a basketball sized rock up on the hill about 250 yards away. Everyone shot up all their ammo and smell didn't even hit the hill. My boss hands me a old S&W 44 mag, and tells me there is one shot left in it. I took my time, and I don't know how but I hit that rock and the 44 mag had enough eMachines to send it rolling down the hill. It was the last time I ever got invited to go shooting after work.

I'm very interested in your success with PB cast. I have the 247 NOE Mold that makes a beautiful bullet and it's a PB Mold. What were you referring to with "per Ben's instruction" and using a drill press?
Thanks;
Gary


[ATACH]2374[/ATTACH] View attachment 2374 View attachment 2375 View attachment 2376 View attachment 2377 View attachment 2378 View attachment 2379 View attachment 2380 Well for me anyways.....

HI GUYS !!!!

Sorry I haven't been able to participate as much as I would have liked to....work has been piling up like crazy .....for some reason..some people can't seem to spend enough money...another time..another...story..

So.. the only shooting I have been able to do was some quick in and out plinking sessions....I checked to see if the smallish group I got with my Remington 700 VS 308 using PB 299's was a freak ...apparently not...(see the appropriate targets)...

I then tried a couple of groups using my two grouve Springfield MK 1 ..... PB 299's and PB 30 H...it's the "Shoot & See" target..not too bad for an overcast damp day and battle sights..

Then I went on to my Rock Island '03 with a good 4 grouve HS barrel.....that was this morning 36%,25 K wind ...straight in my face ...fingers froze up solid...but I got these off....

The molds were PB per Ben's instruction, but done on a wood working drill press...as you can see from the photos my work was less then perfect......

My lessons;
1...don't use a wood drill press
2...Buy a PB mold
3...Listen to Ben
4...for paper work they are as accurate @ 100 yds as gas checked .... either CU or AL, for me anyways..
5...Shoot even if the weather is lousy
6...use a softish alloy ACCOWW's to 4-4-92
7..because they are going so slowly (1300fps) even bad bullets shoot well
& 8...Listen to Ben...

Sorry about not being able to organize the photos..Imgur no longer works for me....Dan

Ya know Dan, I have to agree with you about going back in time! I really like
the statement, and the reality of a different time, generation, etc.

Gary...Ben started shooting PB by drilling out the gas check area of one of his .30 cal. moulds using a 5/16" HS bit ....

Thank you for that info QS, I guess NOE has already taken that chore off my plate. Since I'm using these as subsonic loads, I couldn't see the need for GC's in the first place.
