Reloading question

Is it pretty much a rule of thumb that if you have 2 really tight (i.e. one hole) and one wierd flyer that you bump the powder. I am at the book max but showing no pressure signs. As I went up the flyer got closer.

I am assuming that it isn't the powder or brass or primers because I have 69s one holing and the 55s one holing. They are using more powder and in my manuals it seems like bigger bullets max at less powder. Not sure about the physics of it. Thought I'd need more powder to push a bigger bullet. Bigger bullets equal that much more pressure is everything else is the same?
 
1. What type and caliber of the rifle you are using. Rests?

2. Rules of thumb don't always apply.

3. Like Stephen said....wind flags and consistant trigger pull.

Heavier bullets can use as much or more powder than lighter bullets, BUT the powder has to be slower too.

If you're getting maximum operating pressures with a certain charge of powder and a light bullet, trying to use that same charge with a heavier bullet will increase pressures even more.

It sounds like you're shooting a .223/5.56x45 so you're range of powders is pretty limited especially if you're shooting an AR.
 
Savage 12 LPV 1:9" .223

These aren't called flyers. Shooting one hole with 55 Nosler BTs and 69 SMKs very consitently, put in the A-max at various loads, same length and get two real tight and a crazy flyer. Like 1 two 3 inches. Components same as the consistent 55s and 69s.

Usually when that happens it is from one of the studs hitting something. I have them plenty in front of the front caldwell rest. All metal one. Bag in the rear. I have a lead sled I could use to validate I suppose, but I really got to think it is something with the load.

Any one have luck with another specific powder besides rl15 or varget with these?
 
Problem.....gun doesn't like A-Max's. It's really that simple...go back to the other bullets, maybe try some V-max's

What weight A-Max are you using? If it's the 75 the 1 in 9 twist may not be fast enough. If it's a 55 or 60 gr you might vary seating depth. I've had good luck with A-Max's, Ballistic Tips, and Matchkings, but the seating depth (measured with a comparator) is likely to be different for the various makes of bullets.

For 55 gr bullets H4895 might be useful or Ramshot TAC or W748.

Some will disagree but manual maximums vary from one manual to another for various reasons, not the least of which are bore diameter and variations in powder lots. If the manual maximums seem to be mild increase charges carefully in 1/2 gr increments until you get pressure signs or can't get the bullet seated on top of the powder. In the .223 powders like 4895, Varget, and RL-15 with lighter bullets fill the case before pressures get out of hand.

The Savage is one of the safest actions if something bad happens like a blown primer which is one consolation.

Proceed with caution.
 
Sounds like the usual.
A guy buys a Factory gun. And wants Benchrest quality performance.
It is not happening.
With A BIG NOT HAPPENING!!!!
I know. Thought I could get by. My Savage is a .223 Rem. 1:7".
I shoot local club 200y. Score. Almost every Tues.
Then I met a Real Nice guy. Who had a Custom Rifle. Never seen a custom rifle. What is so special. Except, it costs about 4 X a Factory Rifle(notice. The word Rifle. Not gun.).
Was talking to Steve Theye on the phone. He used to work for Sinclair.
Told me about a Benchrest Group Tournament. Saw a bunch of Custom Rifles.
Talked to Bill Gammon for 3 hours. That was a Friday. Came back Sunday to watch the 200 y. stuff. Was there another 4 hours.
My point. You are in the right place. BC will get you some answers.
But, the standard BS. Try the Factory Forum.
#1 Call Kelbly's and buy a used Bench Rifle. Or Buy new. 6PPC.
#2 Install a forend adapter to your Savage. YOUR RIFLE IS CANTING!!!!!!!
http://www.sinclairintl.com/product/5301/s
That is the reason for the flyers. And maybe your front shooting rest.
#3 Savages' seem to like Lapua 77gn, SMK 69 gn, Nosler CC 68 gn.
#4 Try H322, AA2230, H335 These are all MIL-SPEC powders.
#5 Seat Bullet -.003" from jam. Which dies are you using????
#6 Buy some wind flags. Tom Orlando makes some real nice flags and poles.
The 200y. score target has a 1" 10 ring.
While you are at the Sinclair site. Mike Ratigan put together a real good book. It will save you some money and heart ache.
Like the "old guy says. Just buy the good stuff. Eventually you will."

I had the same issue, though to a lesser degree, in my savage 1:9 when I went to the 75gr amax. I would get some (read rare) groups that were uncharacteristically small say in the mid .3's and then my next group would blow out to nearly an inch. I messed around with seating depth, charge, neck tension, and never could get them to shoot as consistently as the .69's or the 52's.
With the 69's and 52's I can get more consistent 1/2minute performance unless I miss a condition.
I think a 1:8 or 1:7 (whichever is available) is needed to allow the
75's to do their thing. I don't know if you have been over there yet, but www.savageshooters.com has a lot of great guys who know savages like no one else. This topic is brought up a fair deal over there, and it seems to be divided right down the middle. Just depends on how the button was turning that day whether a rifle will like them or not.

Savageshooters.com is a good site.
There might be more to the 4-1 group. It might be where you are shooting.
If shooting out of a building or just a roof and open sides. Wind from behind you will come down the roof. And hit the ground and bounce off the ground.
This has happened where I shoot Benchrest group.
There were enough flags set out. And we were trying to see the wind off the roof. The tails would go straight down and then straight up.
The next set of flags were a little shaky, left right. Then corrected. This was when the wind was gusting and there was a consistent wind also.
The wind that day was all over the place. Usually the wind is west to east.
At another range. no walls just a roof. West to east prevailing winds.
The temp under the roof is sometimes colder. Wind from the west through the benches and over a berm. Moves the bullets up....
But, it might just be the bullets.
