Powder recommendations for 300 Norma Magnum shooting the Berger 230 gr Hybrid OTM Tactical Rifle Bullet.

Powder recommendations for 300 Norma Magnum shooting the Berger 230 gr Hybrid OTM Tactical Rifle Bullet. Users have recommended RL33, N570, Retumbo and H1000 out of a 27 inch barrel.

My Quickload queries suggest N570 and Retumbo have burn rates where the propellant is burn at or close to 100% at the muzzle. Others showed to be slightly faster including N568 by a very narrow margin.

Asking Google AI Search the following “Between RL33, N570, H1000 and retumbo which is the better powder for the 300 norma magnum shooting the Berger 230 gr Hybrid OTM Tactical Rifle Bullet” they came up with N570 or Retumbo.

Below is the Google response. What have you folks found to be your powder of preference?

Response

For a 300 Norma Magnum with a 230 gr Berger OTM, N570 and Retumbo are the best powder choices, with N570 offering potentially higher velocity and good temperature stability, while Retumbo provides excellent accuracy and case fill. RL33 can achieve high velocities but is known to be less temperature stable, and H1000 is a great powder for accuracy but may not reach top velocities for this heavy bullet. Ultimately, the best powder will depend on your specific rifle, and testing both N570 and Retumbo is recommended to determine the optimal load,

Key Powder Considerations

N570:

A strong contender, N570 provides high velocity and good accuracy with heavy bullets, along with good temperature stability. It is a popular choice for both speed and consistency,

Retumbo:

Retumbo is known for producing excellent groups and provides good accuracy for the 230 gr Berger OTM at moderate velocities. It also helps ensure good case fill,

RL33:

While RL33 can achieve velocities over 3000 fps, it is considered more temperature sensitive and can be harder on barrels,

H1000:

H1000 delivers great accuracy and is a reliable choice, but it typically results in lower velocities compared to other powders with this heavy bullet, potentially not reaching the ideal "accuracy node" for speed,
Recommendations

Start with N570 or Retumbo:

These two powders are generally considered the best performers for this specific bullet in the 300 Norma Magnum,

Consider Your Priorities:

If maximum velocity and temperature stability are your main goals, prioritize N570. If peak accuracy and good consistency at a high case fill are your focus. Retumbo is a great option,

Prototype Leupold Ultra 16X-M1

After 40 yrs in the military I found something I cannot positively identify.
I have come to believe it is a prototype sent from Leupold to the military for testing. Any and all help is appreciated.

Sidearms & Scatterguns Good hardside handgun case that can hold larger handguns with optics?

Been looking for a good hardside handgun case for awhile, that will hold 3-4 handguns plus mags, that's not silly expensive. I'm sure I could have something custom made for a pelican etc.

The problem they all seem to have that I've run across is none of them are tall enough to hold a full sized handgun with an optic, esp. if it has a magwell. Something like say an FNX tactical with an SRO or CZ TSO with an optic etc. The same is true for longer handguns like a S&W 41, or a full sized handgun with a threaded barrel. Slap a light/laser on them and it gets even worse because most are spaced so close together that even if you wanted to cut the slots wider to fit the light/laser there isn't enough space between slots to leave any foam. The worst are the cases that tend to hold the guns nose down, because they raise the height of the rear of the gun where the optic is going to be.

Most of the cases only seem to have 5-6" of internal height, even if you removed all the foam that's not enough to fit a full size handgun with an optic and still close the case.

IMR 8208 XBR AND 77gr SMK IN A GAS GUN

1757532287672.png


Just wanted some opinions on this powder and bullet combination for an AR with a 20” barrel and an adjustable gas block.

Typical loads I see online involve charge weights between 23 to 24 grains with a 77gr SMK at 2.24” for Mk262 clones (23.8 grains typical).

From what I can see, this is an accepted norm.

QuickLOAD suggests pressures in excess of of 73,000 psi using this combination, putting it deep into the red zone.

Safe to go this high?

Starting at 23 grains.

Firearms Origin Barreled Action 6Arc w/spare .308 bolt head. (SOLD)

I’m unable to shootto for the foreseeable future since my wife now requires full time care due to early onset Alzheimer’s.
Because of this, I’m paring down some guns, projects and parts from the safe and gun bench. I’ll list these separately.

1. Origin Short Action with 6Arc bolt and 25.5” Douglas 6Arc Barrel, and Triggertech Primary. Includes new .308 bolt head and Action Wrench. Action has less than 30 rounds. Barrel was purchased for this project from a Hide member and has less than 130 rounds. He was seeing under .5moa with it and I saw the same with my first load. Barrel is 1.2” at the action and 1” at the muzzle. I can include the load he was using for the best groups. Trigger has around 1000 rounds on it and is clean and crispy. There is a small ding on the bolt knob just for transparency.
I’m listing this as a set for a while before I think about breaking it up.
$1200 firm plus calculated shipping and as much insurance as you care to add. To your FFL
PayPal or Venmo is fine.
