Last week when back at the hut and hanging up a pig with two mates, the conversation progressed to how to remove blood and clean hunting gear. Both my mates use cold water to remove blood. One...

Looking at that, I think I'm somewhere near the bottom of the curve.

Hope you got a .22 to practice with before using a centerfire. If not, I suggest you go looking for one.

Welcome to the forum ipv. It’s still always good to practise with a .22. A hell of a lot cheaper! I have .22 set ups either the same as my various centrefire rifles or very close. For...

I'm trying the Grendel to get a lighter weight rifle overall but the shorter length is a dream to carry. I reckon if you can manage a 20" barrel you're better to use some of the length and weight to...

From what I have read what your saying is correct. I think there needs to be more training before you can purchase your own firearm. What I am doing to help my self is... 1) Reading the 7...

I suspect @Joe_Bob_Briggs may be trolling us. In case you genuinely don't know, those semi-auto centrefires have all recently been declared to be prohibited firearms in NZ by order of Council. As a...

So, your shorter rounds show less pressure (as shown by ejector marks). That's what you'd expect if you were starting to touch the lands with the 2.260" seating. The key dimension is not COAL...

The SAAMI pressure was relevant at the time to AR based gas guns of which the round was designed for. Also the SAAMI chamber has a stepped throat to lessen the pressure spikes, there is plenty of...

The Grendel Saami pressure is low for Gas Guns, bolt actions can handle a little more depending on brass. I found 28 grains of 8208 to be ridiculously accurate in my Grendel Proof upper :oh noes:

The Q/L results with an 18" barrel - 2425 with 27.7gns. Velocity with the Sierra 123gn at 2.26 COAL is the 2430 and pressure just a tad higher - the same for all intents and purposes. You don't...

You're very close to max with that bullet+powder. ADI 8208 = IMR8208XBR Increasing seating depth can cause dangerous pressure increases with certain powder/bullet/temp combinations. Always use...

Yes, seating deeper increases pressure. But 0.020" won't cause a safe load to become dangerously unsafe. Seating longer can also increase pressure. Without a run up to the rifling, more pressure...

Gidday Pete - I ran these loads in Quickload to see what it said . . . which is only an indication but sometimes helps to understand what is happening. Q/L doesn't have ADI 8208 but it shows IMR...
