I use an ARISAKA tool. An angled piece rests on your rail, and a triangular piece cut to the same angle as a channel in the angled piece slides along between the flat on the bottom of your scope makes contact, and then it is parallel to your rail. It comes with two angled pieces to cover a...

It would be better on the lower ring for ring mounted…for the XLR chassis, can you see it while in shooting position? Someone else had one mounted in their stock…maybe 5 years ago. He had a patent on it, and there were lawsuits involved concerning the infringement where they even went after...

I thought of a few more items: 1. Are all bullets concentric ? Are you using a VLD seating stem? Are you possibly knocking some of them out when loading them into the magazine, or are they getting knocked out going from the magazine to the chamber? 2. As others have mentioned, I too...

Redding named the “type s” die after him. He designed the die type. Initially it was made for him, and as a special order, but they received so many orders for the die that started producing it as one of their production models. The “S” stands for Speedy. I’m off to the range. He is one of...

One more question…do you have the correct twist for the bullet you are shooting? I’ll echo one other cause that someone brought up…parallax. This is one cause that is most often overlooked. It’s. Very easy to maladjust your diopter on many scopes by turning it when increasing or decreasing...

Good advise. Also, with all those shots, it could be the shooter. All my guns shoot better than I do, especially after a long day at the range. If the first four are good, the group can only stay the same, or get bigger. If it’s not a hunting gun, there is a recent thread written by someone...

Old powder, although it is usable and might be reliable, does degrade over time and might not perform as listed in the old data. Where and how it’s stored…temperature and humidity…type of container…matters more than the age of the powder…from what I have read. I think your powder container...

None of those calibers were born yet, but Bo gave me an idea…these are from Sierra #3…1989, I’ll send them in 2 or 3 batches.

Taken from: Speer Reloading Manual #3, circa. 1959. Advise of any other caliber(s) you need.

I agree with everything said thus far. I’ll add some additional advice in the form of questions :How far do you hunt from your vehicle, or camp? Are you a good shot, or do you miss a lot.? Do you hunt with a spotter? Will you be shooting at registered targets, …will you know the exact range...

The rifle was headspaced incorrectly by the gunsmith. I brought it back to him, and he said he knew exactly what happened. From what I remember, he said he was trying to figure out why he had an extra recoil lug for a 700 Remington, or a recoil lug that was unidentified; in any event, the...

While doing load development for a new custom .338 Lapua, I started low and experienced high pressure signs. I Reduced the load to the point that Vo was 2250 with Berger 300 gr. elite hunters. I still had the flattest primers I had ever seen. I knew there was something else wrong. The issue...

I take measured velocities from Lab radar and compare them to velocities of the same bullet charts of different BCs for the same bullet…I start with the published BC…e.g. G1 = .320, and do charts for .310, .300, etc. until I get a close correlation. I just did one for Powerbelt 270, .50 cal...
