As marketed, the velocity and Electricity match up with other near competition, however the velocity I calculated averaged 1135 feet-per-second outside of a five-inch barrel—slightly slower than advertised.
Now triggers are An additional Tale. I have experienced challenges here. I’ve had problems with two Jewell triggers over the years. I’ve blown up at least 1 or 2 Timney triggers early on After i was stepping into this also. But, I'm able to say with a hundred% honesty which i’ve hardly ever, at any time, at any time experienced a difficulty that has a TriggerTech. I’ve never ever observed or heard of somebody obtaining a problem with a single possibly, While I’m sure it’s took place. It just ought to not be Regular whatsoever. I haven’t considered this till just now, but I believe this tells it all: After i accustomed to shoot Jewell triggers, I’d carry lighter fluid with me in my pack throughout every match. Given that I’ve been applying TriggerTech’s for a number of many years, I couldn’t even tell you if I had lighter fluid any more!
To the question about firing pin sizing, I’ve normally heard the scaled-down the higher. I believe that’s because a lesser firing pin is purported to give extra steady ignition, and dependable ignition leads to decrease SD’s. I've heard guys indicating that when talking about mid-sized quick-action cartridges, similar to the Creedmoor, Dasher/BR, and x47 Lapua instances, so I’m not sure how much that relates to magnums.
The AI bring about is additionally a two-phase bring about, and I Individually want single-stage triggers, such as TriggerTech Diamond. I'm thoroughly aware about the safety benefits of a two-phase bring about and might understand why they went with that style decision. Nevertheless, I’ve been running a TriggerTech Diamond in all my rifles for two or three a long time and it’s still my own choice. The TriggerTech Diamond is adjustable all the way down to four ounces, Whilst I usually operate mine from 10-fourteen ounces. Not too long ago I read an post in Precision Rifle Shooter magazine where by somebody questioned TriggerTech’s VP of Operations, Quinn Richardson, In the event the 4-ounce Diamond bring about could handle a drop exam without firing. A tiny bit to my surprise, Richardson replied, “The 4-ounce pull weight minimum amount to the Diamond permits the shooter to run the bolt in a short time without stressing with regards to the firing pin pursuing the bolt physique.
A further superb monolithic choice for wilderness bear defense may be the 145-grain Woodsman from G9 Defense. This monolithic copper slug includes a truncated idea, but includes a Centre spike with radius edges that sweep all the way down to the flat place. This small characteristic triggers dramatic cavitation in comfortable tissue, exactly where flat-nosed slugs only punch a wadcutter-like gap straight as a result of. The top products is often a high-velocity bullet that is great at punching by hide and bone, but inflicts a great deal armalite ar19 of tissue destruction at the same time — one thing you would like when endeavoring to quit a toothy attacker. The lighter projectile weight brings about significantly less recoil than all kinds of other 10mm loads, and makes exceptional accuracy.

The QUICKLOC barrel release housing is found during the reduce-appropriate side in the action, demanding forty nine inch lbs. of torque when installing a whole new barrel. Bolt bodies may be transformed with out applications though using the initial Shroud and Firing Pin Assembly. Further than the redesign on the chassis, the Procedure of This method is similar on the AXMC.
I wound up firing Nearly 500 rounds through the AI AXSR over the couple of months that I had it, so I’d choose to share along with you guys a a hundred% straightforward review and total disclosure on what I liked about it and what I didn’t like.
As I explained stated, The point that Lapua released brass with the 300 Norma Mag is the main explanation I selected to operate that cartridge once more during the Nightforce ELR Metal Challenge this 12 months. In earlier years I employed Norma brass, and I by no means could get my muzzle velocity as reliable as I would like.
Wow! The examination included fifty rifles and over 2500 shots! That sounds like some major investigation, And that i’d Consider People results are conclusive. Thanks, Scott, to your willingness to share that with the rest of us!
