I started working up a .270 load with a 110 gr ttsx . Started with h380 ,h4350 then ramshot hunter. 60 ish grains of Hunter has been the best powder I've used in 30-06 and barns online data has it listed as the fastest load for the .270 110's but I thought it was strange the max change was 65+ gr...Started at 63 gr and it almost filled the case completely. Either I need glasses or their data is bad. photo uploadH4350 was the slowest of the 3 but it was by far the most accurate.

It list it as a compressed load at max. What did you expect?

Nothing wrong with compressed loads.
Use a drop tube.

You may be able to barely seat a flat base bullet into the 63 gr charge but there ain't no way a boat tail and 2.7 more gr powder is going fit in that case. I've loaded a couple compressed loads before with RL19and 4350 but never compressed a ball powder load.

When I started rolling my own in they eighties, the Hornady load book listed a max charge of 53 gr 4350 with 139 gr bullets for 7x57. That charge would almost fill the case to the top of the neck.
Oh well. Place a bullet on top a listen to the powder crunch.
And a drop tube will help compress ball powders also.

I’ve got a load that I use in my 308 that I have to place the bullet on the powder. Lol. It’s a book max load. It’s an awesome load for me.

Here's hodgdon with Hornady 110gr and usually Barnes or all copper bullets call for less powder . This is why I like to use several reloading books or sources then make a educated guess at good starting point.yeah that 65gr does seem hot but I haven't looked at any other manuals to see

Yep, inconsistent loading depth is a real thing with compressed loads. Load a bullet in an empty case and use that as your baseline to compare loaded rounds.

You can always work your way up till you see pressure signs.ill load sometimes up to 2gr's over max in 3 round batches doing ladder test . usually what I do sometimes I have to pull bullets and use those for fouling shots later on but it's part of it.but alot sometimes I'm seating well beyond magazine length so I can play around with charge weights in those rifles. Just keep loading in small batches till find max and pull bullets in the rest.what I do anyway Then use info from those groups to start what internet guys call OCW test.pretty much what I've always done on load development
