The archery season starts here during the warm weather in Sept, and it is usually still decent in Oct. By the end Nov it is cold and thatís when rifle season starts. I donít know of any hunter who ages their venison. As long as itís cold and theyíre not in a hurry, theyíll keep hunting. Iíve let one hang overnight and that was because I didnít have time to finish it the night it was taken.

Several years ago I spoke with a man who lived and hunted on Kodiak Island for 20 years, I think it was. I know he said his do-everything load was 150 grain Partitions with a 270 Winchester. Therefore, I would go for the Partition.

When I hear the pleas of ďwe would have won without the A-bombs because Japan was on the brink of surrenderĒ I ask who was ready to surrender? The emperor, the military on the main islands, the forces off of the main islands? I sure donít know OR believe surrender was in their plans.

I had a black plastic M-16 look-alike. I got it around 1972. With five or six pulls on the charging handle I could rattle off about 20 seconds of what sounded like automatic fire. The magazine contained the speaker. I have no idea how the noise was made but no batteries were required.
My dad made some Luger pistol cut-outs from some wide pieces of yellow pine. We never got hurt playing Army or Cowboys and Indians.
These days some people would freak out over the harmless things we did with pretend firearms. Maybe we were smarter kids than todayís crop and had better parents?

With one exception, my most accurate rifles are bedded. The Sporter stock with my 300 Wby is not bedded. It produces sub MOA groups anyway and any deer Iíve hit with a bullet from that rifle has fallen within a few steps.

The Bell & Carlson stocks have a metallic frame that makes an extraordinary tight fit on the receiver and it can be bedded. You likely wonít gain much but it will help some.

I think the sponsoring company sets the limits and submits it for testing.
Example: the 416 Remington is loaded to a much higher pressure than a 416 Rigby but the Rem has lower muzzle velocities. Noslerís recent cartridges based on the 404 Jeffrey case are at a much higher pressure than the .423 caliber was designed for. I believe it was Dubyam who said to get the velocities they were after Nosler pushed the pressures way up. Itís simple physics. Remington and Nosler squeezed out what they could from the limits of the case in a modern action.

When Roy Weatherby developed his first magnums the slowest burning powder readily available was IMR-4350. There was a big war going on, so that may have played a factor in what was available. I donít know what slow burning powders were available when Remingtonís 7mm mag was developed.

As was pointed out, the freebore helps keep pressures lower with Weatherby cartridges while still getting great velocity across bullet weights. A gunsmith described the 7mm Rem chamber as being choked when compared to the 7mm Weatherby.

Musicmanó-Springfield Armory is making the M-1A in 6.5mm Creedmoor for the same price as the 308 Win.

The V3 model is almost twice the price of the Sporter model. I have the Sporter. It keeps track of the last 50 or so shots so if you donít see the readout fast enough you can still get to it. There is no date -time with it, simply the velocity.
The mount works with a braked barrel as long as the brake is not too large in diameter. I only use it after determining if the load is accurate enough. With my 280 Rem, 300 Wby, and 9.3x62 Mauser there is no POI shift when using the chrony.

My chronograph readings with a light-based unit were all over the place depending on the weather/lighting. Since going to a MagnetoSpeed chronograph those iffy velocity issues are gone. I trust itís sensings.

375 H&H or 375 Wby. Your other calibers cover it all.

Griz 340: How much time do you have between shots? About how many rounds have you fired with this barrel? Tossing out the slowest and fastest of the recent readings, your load is about 2880. The question is, will the speeds increase with weather changes effecting the powder?

I have never heard of rebluing doing anything to velocity. Itís possible you simply have enough barrel wear that velocity is down. However, Iíve found whatever a book load is compared to what truly happens on a good chronograph is almost always different.

I have heard of a way to get velocity levels back with the same loads once those speeds start slowing down.

There are plenty of routines for the number of shots fired between cleanings and how much cleaning to do. No matter what break in method used, donít get the barrel hot to the touch. Letting the barrel cool will help avoid unusual wear on the bore, especially on the leade where the temperature is the highest.

There is no formula for determining how many shot have to be fired of a certain bullet type (all- copper, jacketed copper mix, or a combo of both) in order to smooth the rough spots or fill the holes in the bore to sharpen your accuracy. Your barrel will let you know.

There will be barrels that seem to need no break in. Lately, they more common than you might think. Perhaps I have been lucky in that area.

The simple, 180 grain Hornady Interlock in either the flat bottom or boat tail style is lights out, dead accurate vs deer with my 300 Weatherby. Iíve used handloads of H-4831 and factory loads with the Norma bullets replaced with the Interlocks. RL-26 produced the highest muzzle velocities but Iíve not hunted with it. For now, Iím sold on those ordinary Hornady bullets in my 300 Wby.
