22 ppc LOAD INFO PLEASE

[snert]

I have a base load of 25 grains LT32 and a 52 grain Berger. Any 22 PPC experienced guys that can tell me what the top end is so I stay away from it? I do not have a chrono and I am not seeing any pressure issues.

Most reloading manuals give a FPS reading (average) along with the load data they give for reloading a cartridge. What does the manual/s you use show ? That would give you a estimate of the FPS.

Doesn't matter what anyone says is their experience. Always watch for pressure.
When I am concerned about pressure, I work up to it slowly and carefully. Then I know not to go.

Littlebuddybr nailed it. Every firearm in different, what may be a safe load in mine, may be too high for yours. You must work up each load and what you are using, in your firearm and stop when it shows you it's limit.

My four manuals have no info on 22 PPC. I started at 25 grains. I'm looking for a max load (so I don't get near it)

Does not answer your question, but I had the best luck in mine shooting Ramshot Exterminator at 3500 fps. 52 grain Berger and 205.

My manual doesn't have LT32. Here are the MAX it lists:

748 - 29gn
H322 - 25.9gn
N-133 - 24.9gn
AA2230 - 24.6gn

Given that, you can definitely say 29 is too high for LT-32.

Here's something from the past: https://forum.accurateshooter.com/threads/22ppc-with-lt-32.3840520/

25gns is definitely in the ballpark, so why not work up from there to the first good node you find and use that?

Thanks Evan, I missed that thread in a search. I appreciate the help

I don't have any data on lt-32.
But here is what I found in my sierra manual.
Well, the picture is to large to load.
I don't know how to make it smaller.
If you send me a pm with an email or phone #. I can send it over that way

While it's not LT32 powder, Vihtavuori has data and burn-rate can help establish your upper ballpark. I don't suppose you've called Accurate Arms/Western Powders/Hodgdon for data. AA has data for the 20PPC and the 6PPC, seems they'd have something for the .22.

Work up in .3g increments, you will know when you hit top end.

Powder changes over time, I shot very tight groups from 27.5-28.5g with 52g Remingtons in Sako balloon case head brass.

I won a match with 25g of IMR 4198 and 52g Remingtons, agg was .189 and the Warm up was .069
Sako Balloon head cases, fed 205, Hart 14T

I use VV N133 with 52 Bergers. Shoots extremely well at 26.0 Grains in 22 inch barrel. Tried LT-32 with 52 Bergers-shot best at 24.5 Gr.
