You asked; Will a .010" change in seating depth matter if your already 1/4" from the lands starting out? From my experience and testing my answer is absolutely yes. I did a lot of testing of this subject some time back and perhaps my comments are relative. At least for those who are just...
I had two back decades ago. A .243 and a .22-250 both rifles. I did a full bedding including the barrel channel, leaving the barrels free floated. I was a tool and die maker and I built an adjustable trigger for each.
The .22-250 shot the best. Most of my developed loads shot .250 and under...
I've used RemOil in all my barrels, including my flintlocks, for 20 years or more with no problems or loss of accuracy. Before I hunt or even just shoot any of my guns I run dry patches through until I see no trace of the oil on the patch. I expect and get the same accuracy as the last time I...
I left the house with plenty of time before daybreak, and there I was just driving in the dark, thinking about the hunt ahead when it ocurred to me I had left my turkey vest at home. I had made about 20 miles of a 25 mile trip but there was nothing to be done but turn around and go back home. So...
IMR4350 is my go to powder for the 7 mag. It has been for 30 years or so. Now don't think I haven't tried other powders because I have. It's just that IMR4350 always beats the others out.
I load for the 7mm Rem mag and the 300 Win. mag, both are belted cases. I like a belted case. I size mine just enough to fit my chamber and no more. This prevents the case from stretching and splitting.
About your primers seating proud of the primer pocket, this is caused by the little radius at...
I use a "uniformer" also. I use it to remove the small radius at the bottom of the primer cup. The radius keeps your primer close to the surface of the case. When you rub your finger across it you can often feel the primer high in places. After using the uniformer the primer will always be just...
My 7mm was my regular rifle for at least a decade hunting the thick swamps of Central Georgia. Full house loads ruined a lot of meat and were not needed at such close range. So I loaded 154 grain Hornady spire points to the lowest listed loads.
I used IMR 4350 and the loads worked perfect. A lot...
I harvested this big Doe Thursday morning at 9 AM. She was 75 yards away and in shadow as the sun had not yet lit the woods. I hate to admit it but I made a bad shot hitting her high and left. I made a bad shot. Nothing else to really say about that.
The ball hit high causing a sporadic blood...
I know this is an old post, but I did a lot of testing of this subject some time back and perhaps my comments are relative. At least for those who are just thinking of using seating depth to improve accuracy.
I never measure OAL, it is not relative to what I do. I only measure to the ogive and I...
A few years ago I was ready to rebarrel my old 7mm mag. The old one just seemed "tired" to me. But before I did it I decided to give the old one another chance, so I bedded the stock, did some work on the old walker trigger, and really dug down and worked up some loads that really fit the...
I've got one of those useless, out of date .308's myself. I don't know yet what I'm going to do about it. In the meantime I'll keep shooting it and hope I don't get caught.
Watch for falling trees. I'm not kidding.
CL, I would look to my setup before trying anything new. Whatever you use, sandbags, front adjustable rest, whatever, it must be rock solid.
Once you get the height worked out for the front rest, on the stock not the barrel, then partially fill a sandbag for the rear and leave it a little loose...
You never can tell. A few years ago I shot a really big boar with my 7mm mag. I shot it just under and in front of the ear. I was sure it would shatter the skull but it didn't, just 2 clean holes, in and out.
Sure killed that old boar though.
I want a free floated barrel if possible so I always remove the bumps often found in factory stocks and start from there.
I think the factory bumps help modulate the oscillation of the barrel. Seldom does this give tiny groups but it will allow passable groups for most shooters.
I've also...
