Working up a load for my "new" 1992 Browning Bar 338 Win Mag.

FWIW, I have found that for loctited screws, applying a soldering iron directly to the screw usually works. I would go this method first before using a torch.

I'm afraid that a pressure cooker wouldn't help one bit.

Not at all, lol.

I tried that to no avail so I reluctantly had to take it to a gunsmith. Watching the gunsmith heat my pristine 1992 Browning Bar 338 to the point that smoke was boiling out of causing me to have flashbacks from my firefighter days. There's NO WAY IM HƐLL that I could have done that to my gun. At one point the very old GS sporting gnarled drawn up fingers with thick glasses and an unlit cigarette hanging from his lips says to me to. "Let me know when it starts smoking?" With a lump in my throat while fighting back projectile vomit I replied. "It's been smoking for 10-15 seconds." He said, "good, that means the LocTite is turning loose." My guts nearly turned loose in my trousers. That was an AWFUL AWFUL experience that I have no desire to ever see again. Sorry for the delay response. I've been working on get the mounts and scope on the new rifle and loading ammo and doing what we do. Load, fire, write down results, rinse and repeat.

Welcome to the 338 Club. Not a bad place to be. FWIW, there’s no such thing as overkill. I use a custom 700 338 RUM as my main crop damage deer rifle. The 250 AB absolutely crushes those bean bandits.
The 210 PT at 2900-3000 fps is an excellent bullet that opens up well, even on deer and penetrates deep. You are able to hunt most anything in NA. Keep an eye out for the 200 gr AB and/or BT (Ballistic Silver Tip seconds).
The 210 PT and 200 BT/BST shot to the same POI in my 338 RUM.
RL19, IMR4350 and H4831SC would be good powders to start with. The 225 AB is another good option that won’t disappoint.
You shouldn’t have any issues sizing up 7mm Rem Mag cases to 338 but I would recommend annealing the cases first and neck up to .308 and than .338 to prevent splitting the necks.
I’m my experience the 338 hits hard and kills fast.

I have had single digit extreme spreads and standard deviations with this 338 and several different powders and powder charges. Is than normal with this caliber? Ive never loaded anything close to these type numbers before. However, sadly, 63 grains of H380 underneath a 225 grain AccuBond at an ave of 2,512 FPS has been the clear winner. A 6-shot group was really tight especially when you factor in these temperatures and starting with a warm barrel. N-560, IMR4350 & H4831SC have produced unacceptable accuracy thus far. However, the ONE group that I shot with H4831SC was pretty good but barely 2,500 FPS. My new gun does NOT seem to like speed.

This is my private little rifle range. Reckon how many rifle balls it took to shoot all these big oak and sweet gum trees down? There's multiple trees on the dirt including two that would have been hard if not impossible for me to reach around. I've been shooting at this particular place for 6 or so years now. I tried to get down yonder and get you a picture of the huge hole in the ground that has been blown out. But I am wearing a pair of Alabama Crimson Tide Crocs and a pair of sleeping shorts.

That center target was shot with 73 Grains of H4831SC under the 225 Gr. Nosler AB. That group average less than 2,500 FPS and 1¾". Not great but it gives me hope considering some of the, what I call hubcap sized groups, that I've shot between yesterday evening and this morning.

I've just finished up cleaning, resizing and priming my brass with Remington Magnum Primers. I bought them a couple of years ago but I've always used WLRM. Any thoughts on the Magnum Remington Primers?

Ive been shooting my rifle as it came to me up until now. I cleaned the bore up good with solvent and such and a brash then a few cleaning patches. I'm about to go fire a fouling shot. Then I'm just waiting for the mail to run and hopefully load some 210 NP and get back at it.
