6PPC - I'd like to try the sweet spot above 29 gr of N133

More powder = less brass life. If you are shooting in completion that is one thing. Informal matches are another.
Who sells Alpha brass and where is it made?

Midway & Brunos & Blue collar would be a few options to find the 6ppc brass.

Does Alpha Munitions manufacture their brass in house?​

All Alpha munitions products are designed and manufactured in our state of the art facility in Salt Lake City, Utah.

Like Chris and Charles are saying don’t get hung up or make the mistake in thinking you can shoot better or smaller at a hotter load.
BUT! Like Chris said on that day it may be the right place to be

I shoot a lot of group and score and still load at the range I’m not smart enough to pre load
Some days 30.4 is a hammer some days it’s spitting shots everywhere and 29.7 is hammering

You do need to learn a particular bullet. If I had to preload it would be 30 grains

Curiosity has gotten the best of me, i knew to the 6ppc and was wondering where the velocities are running with 30.4, 30.5 of N133 and what length barrel?
Thank you Sir.

Thank you Sir.

Out of a 22 inch LV barrel, around 3430 to 3450 fps.

Have you ever had the barrel set back an if not, have you checked the throat erosion now compared to when it was first chambered. Just wondering my reamer has .040 freebore I was just curious to see when the avengers start to see little bearing surface in the case neck after 1700 rds. Thanks.

No on the set back.
I'll look when i starting loading for it in a few days. I haven't chased the lands at all. Started at touch. sure it's cracked up and starting to copper.

I don't clean it hard down to the steel. Just a few strokes with a bronz brush and a bunch of patches. Boretec elemator, #9 mostly.
I have used wipe out, but the patches do not show allot after so i didn't deal with the mess.

The brass has gotten old and they have started sealing at the base of the shoulder. It's was black in the sholder area ! Still shooting really good.

Some of the pockets are really loose also but i hate to change anything. I think this is their 2nd barrel. So about 3k rounds ! I don't keep up with rounds on the brass, just the barrel.
The next barrel gets new brass.

Thank you for the response and I'll keep a lookout for your next post on this. Thanks again.

Perhaps it’s already been said as I didn’t read every comment. To find the sweet spot on a 6ppc “ my favorite cartridge of all time” you must learn to read groups and load at the range. It’s takes time and dedication. No magical powder drop can achieve this. With that said I’ve shot upwards of 31gr of 133 in the past with no issues in my Bat DS. You will need a long drop tube to do it. You don’t need to do it though.

How much extra powder will a .035 to .040 freebore allow, over a zero freebore?

The 6PPC usually has a freebore more than .035

It never differs from flatbase to boattail?

The boat tail on these 65 grain bullets isn't very long.

The trick to shooting N133 is to understand that you HAVE to constantly pay attention to your targets and the environmental and make adjustments if you want to it to shoot small.

Here's the scenario I've seen a thousand times.... a normal, average shooter with decent equipment tunes on Friday and starts the yardage Sat morning with in first place with a .130. He knows his tune is perfect. Second group is a .105 and he is smiling to himself, way ahead of the pack. By 10:45 the temp has come up about 10-15 degrees from where the day started, but the gun is so perfect. Third group has 4 shots in another .110, but the last shot blew it out to a .345. Still in 4th place, must have missed a condition... the load is perfect. Around 11:15 he shoots the 4th group and temp has only come up a few more degrees. ARGH - .405 - none of the bullets touch. Did the scope break? Middle of the pack again. Damn. Change the powder, up, down, doesn't matter, next group is a .290, and he finishes in 11th with a .255 agg.

After this happened to me (about 100 times!), I finally studied why it wasn't happening to those top-10 guys. The general advice boils down to this... change BEFORE the load blows up.

Change your powder, your seating depth, your tuner, your charge weight, change something! That tiny .105 is sending you a message that in 3-5 more degrees it will be a 4-and-1 or 3-and-2. Ignore that and a 5-of-diamonds is only 3-5 more degrees away.

When I was shooting 133, I could have preloaded for the whole season - shot 28.7 and never touched the seating die. But I adjusted my tuner just a smidge nearly every target. 1-1/4 thou per degree of temp change did a really good job of eliminating those big threes and fours.

P.S. Now I'm shooting LT31... the load and seating depth hasn't changed in 12,000 rounds. Still tweak the tuner just a smidge if the day gets hot to keep it honest.

Pure GOLD!!!!
