I found a good article by Brian Litz on the benefits of this “In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short.” “After all, when you seat the bullet out longer and leave more internal case volume for powder, your effectively making the cartridge into a bigger cartridge by increasing the size of the combustion chamber.”

My 7 saum is not far off a 7 prc with a 20” barrel velocity wise.

Gone to harder ADG brass from norma 300 saum necked down.

I think barrels make a difference too some just seem faster.

Both the ones I load for are 20” on short actions seated at 2.935 I have friends with xm actions with reloader 26 they pressure out the same the only effect on velocity is barrel length the long loaded rounds are better if using 2217 I don’t believe in faster barrels just tighter chambers pushing the pressure up you’ll find your 64.5 grains will be near the same pressure as my 62 grains

And yes the xm loaded long requires more powder to achieve the same velocity’s than loaded short but no matter the action length the velocity’s are relevantto pressure theirs still room in the case with 26 loaded at 2.935

Yeah I could probably work around 65 gn if i wanted to push to the max.

Sometimes results generate a bit of head scratching- first loads with RL26 loaded to 2.990” coal 63 gn = 2622 rather underwhelming to say the least. Read the Litz article and increased coal to 3.125 just off the lands 63 gn produced 2820. It surprised me that the change in coal increased pressure/velocity that much. I did change from a magneto speed to the garmin in between times but don’t feel that influenced outcome.

Closer to the lands less pressure escaping in front of the projectile not uncommon your sitting at a primo speed for performance with that pill you’ll have nothing but good times with it I’d say your velocity is right where it wants to be

Small 7mm addiction when you can load a little bit of a lot rather than a lot of one to brake a barrel in 5 of 10 different projos to break in the new saum barrel

Big weekend, lots of annealing and 100x 30-06 rounds loaded 50 x ai and 50 x fire forming rounds
Along with prepping 95 x 308win cases.

28x rounds of 30-40 US Govt for my 1885 which has been my primary rifle for the month.



W760 powder and Hornady 180 grain bullets.
Shot 2 goats and 2 deer with them in the last 2 weeks out to 215m and getting pretty confident that they are doing enough damage for it to be a 300m capable deer rifle

A couple for the young fellas 130 years old girl.

Just loaded another 8x 577-500 #2 Express rounds so I can go hunting properly

Left is a 222R
Right is a 30-40 US Govt

Well, someone on this forum's signature says it all - overkill is still dead!

I only have 11 rounds ( is that the right word for something that big ) with me, so I had better make them all count

A miss might scare it to death? not too dissimilar...

Took my new howa Superlite out today and used my last 4 handmade from my previous howa 1500 to see if it would shoot the same recipe.
Thankfully it does, so loaded up 50 more 165gn speer btsp's

Shot 4 rounds into under an inch....wish I'd noticed I was on 4x before the last 2 rounds, and it would have likely been even tighter group.
Will get some more group data when I krono the load later next week.
