5th firing on this brass, never annealed. Sized with SAC bushing dies, primed, powder weighed with a Chargemaster, bullet seated to mag length, dry tumbled after loading to remove sizing lube. View attachment 699156View attachment 699164
Beauty of a group!!

12 shot group at 108 yards with a 7-300 Norma. 180 ELDM at 3150fps. Also no load development. Just consistent brass prep and forgiving bullet design.

Is everyone checking shoulder bump with a case gauge or comparator or just confirming they chamber in your rifle?

Both. Sometimes .002 on the bump gauge isn’t enough to allow totally free function of that bolt. So lately I’ve been pulling the bolt apart and knocking the ejector out so it’s totally free from tension, and then sizing the brass until it closes without any resistance.

But a .002 bump is going to allow you to close the bolt normally most of the time

I like this reloading method a lot.

Spun a new 6.5cm barrel onto my old T3 in January, its third barrel. Loaded up 20 rounds with 41g H4350, seated a 140eldm .020 off. Three shots to get on paper and rough zero. The next 10:

Adjusted up .1, then five more shots to true solver at 765 yards for a hunt. Shot #19 killed an Elk. Less than a box of rounds to be load-developed, zeroed, trued, and put 200+ pounds of meat in the freezer.

Shot another 200 rounds through this rifle in field practice, then spun on a muzzle brake to shoot a match. 10 shot group with the brake, adjust windage .3 right, and then true solver at 986 yards for the match. Same original load, and the barrel has never been cleaned.

Beautiful work!

I just did a 9 shot group in the evening to set my zero on my final load. 180 ELDM at 3160fps. Came up .1 and right .1.

Then in the morning went straight to 1220 yards to true the BC.


Came out to .385 G7. Impacts line up really well all the way out as well. Tested at 500, 700 & 900 yards afterwards.

I did do a small charge weight “tune” or test at 730 yards.

83.5gr

84gr.

While both groups were good. And potentially even the same shot over a large sample and repeated several times. I went with 83.5 for the lack of vertical dispersion in this small test.

How many rounds you shooting through the barrel before swapping them out?

Is that the barrel you haven't cleaned in like 600rds and PVA (IIRC) was begging you on IG? :LOL:
Yeah lol
Tumble after loading? Any particular reason for that as opposed to tumbling before loading?
Don't have to dump media out of the case or poke bits out of the flash hole. I know stuff in the flash hole probably doesn't matter, but knowing its there bugs me lol

Haha that's wild. I have never heard of anyone vibrating a batch of fully loaded rounds.

I definitely did some googling to see if anyone else had done it before I tried it lol. No problems thus far 😅
Once you prove it to yourself, that’s all that matters! If you eliminate some steps and still get good performance, can’t argue with that man! 👊🏼👊🏼
