Safety first.

Lions, tigers, and bears, oh my

The belt was originally designed to control headspace on the 300 H&H, which has a very slight, long shoulder. Modern magnums have a defined shoulder to measure headspace. How many belted magnums really need that belt?

H4895 or N140 for 130 gr bullets. I use N150 long barrel with SMK 168.

The overbore is right up there with 25-06. I have both and a 10 shot string will heat them up quick. 9 twist on both. That is what the barrel nut is for. They're fire breathing dragons.

You need exactly 100 yards and the scope needs to be stabilized. There is no shooting involved. Your only estimating here and a chunk of 3% can certainly put it in the noise.

Did you true your bc at each distance. Strelok allows you to do that on the target as well as adjust your scope click value if needed. This is why Strelok and other apps have a banded BC option aka drag curves. Your starting point is a good avg MV in any case.

Are you using multiple BCs in Strelok or one single BC?

Rely on the fundamentals. Bullet choice and within a more than reasonable calculated point blank range based on your ability as a rifleman in good weather conditions. This may be the underlying reason, as you mentioned, you've heard a lot of people go back and forth.

I also have his digital headspace gauge in my Willis collection. He turned down offers by Hornady to buy his patents. The guy was super stubborn and a little off the map. He wasn't in it for the money and could care less about business. Eccentric is the word I'm looking for. The fact that...

I only use it on 300 H&H. This cartridge headspaces off the belt for a reason. Thus, slight bulging of the web after a few firings is not necessarily running too hot without going into a lot of details. I think Willis is misleading people a little on the die use on modern magnums that...

Measure unfired brass with fired brass at the thickest part of the head.

I use that in .300 H&H.

These cheap scales get by using calculated weighted averages over time only to find out they are within the advertised error rate. Apples and oranges.

Lab grade scale. I think the subject matter is a proven non-issue on weight quality control.
