Willow, I don't remember the jump but it was not much. My COL was 3.112". I am shooting a 28" barrel, using RL-16 which is more expensive in OZ than here in the states. But, I am driving them mildly at 2825 fps. My 600 yd group was 2.04" and the 1000 yd group was 3.56". I have sh...

When I first built my 284 WIN, I tried SMK 175 gr, 180 gr Hybrid and 162 gr A-MAX. the A-MAX shot better than all the rest so I stuck with them. Along comes the ELD-M series so I tried the 162's and they shot as good as or better than the A-MAXs. I bought a box of 180 ELD-M to try"later." ...

Geoff, I drilled a hole to clear the 0.2" glass rod on the centerline of the vertical induction coil. Then I put a rod in a case and mark the rod with a felt pen where the rod exits the neck. Then I put a glass rod in the hole in the plastic sheet and measure from the rod end in the bottom of t...

I wanted an inductive annealer and I believe the AMP was the best on the market. But, I have champagne tastes and a beer budget! So, I bought an ANNIE. I experimented with all different coils as well as made some of my own. i finalized on the water cooled coil. I did many tests with Tempilac and det...

I also use LEE collet dies exclusively.

If you are leaving die marks on the necks, you are using WAY too much pressure. Go to P 1 and re-read ALL of scott/r's re-print of John Valentine's article on how to use and set up a LEE collet die.

Lee does make a custom 284 WIN collet die. I use one for my F Class gun.

I started with my 284 WIN with samples of 175gr SMK, 180 gr Hybrid and 162gr A-MAX. Both the Hybrid and SMK shot about the same, but the 162 A-MAX outdid both of the others. When the A-MAX became un-obtainium, I switched to the 162 gr ELD-M and they did even better. I bought a box of 180gr ELD-M as ...

Even though you guys beat the USA team, you deserve congratulations!

As I was somewhat aware of some of the things done by the Australian team, I warned some of my F-Class friends that they may be beat this year, but no one listened!!

A truly scientific effort!

I have been watching this device since it was released. As I worked in the hearing aid business, I am no stranger to directional microphones I sent the designer some data on various microphone arrays to minimize the inclusion of neighboring shots. This device is placed on the ground or on stands wit...

I changed from IMR4831sc (don't know the ADI number) and changed to RL-17 with good results. RL-16 has just been issued
and I am in the process of switching over due to better temp effects.
QL claims same weight as RL-17 gives same velocity and barrel time!

I stand by my "No Ear Muffs" above.

We will gladly spend $2000 for a new scope but balk at a couple hundred dollars for competent, comfortable and safe hearing protection.

Longranger, GSP-15's plus electronic ear muffs, Not really a benefit as the properly inserted GSP-15 offers close to 40 db of attenuation. That plus the 26dB or so from the muffs totals 55 dB or so, but your pesky mastoid bone screws up the works by paralleling the 55 dB from muff and GSP with 40 or...

Did I hear some one call my name?? I have commented on this subject so much on 6mmBR that I'm sure folks are tired of seeing my name! I am first an Electronic Engineer and designed analog Bipolar Integrated circuits for 40 years. My last job prior to retiring was for a company that did research and ...

Norm, I got my 105 RDF's from Shooter's Pro Shop in Bend Oregon. They have been selling RDF "seconds" at VERY low prices. They claim they are only visual blemishes. I and other customers can't seem to find any blemishes on them! Apparently, this shop has very close connections to Nosler an...

For what it's worth, Brian Litz, the ballistician at Berger Bullets, stated that practically speaking base to ogive is 1. easier to measure than bearing surface and, 2. any error in measurement relative to bearing surface is trivial.
