load data for 6ppc

[Webphut]

I have not been able to locate any commercially documented load data for a 6ppc using Berger 6mm 64 grain BR Column bullets with LT-32 powder.

My receiver and bolt are factory sako L461 with a custom SS straight contour .262 NK. 1-13.5" twist barrel.

I contacted Berger Bullets and they referrred me to their reload manual, which I have, but unfortunately it does not list LT-32.

Have you tried western powder to see if they have any info? In that rifle id start around 26gr and work up slowly

 

[Webphut]

Yes, I actually have printed copies of all the load data from both Berger bullets and Western Powder.

Funny thing, it’s suppose to be this super popular powder, but I guess just not in this particular combination.

If I had the experience as far as exploring with pressures and swapping bullets for powders, I would just do it and play with the loads until I felt safety was a concern, but I am uncomfortable with this because of Having zero experience with stepping outside of what’s documented and all the myths, legends, and what have you’s.

26 grains sounds about where I was thinking of starting. May you please define “slowly”? .5 grain increments? or more like .2 grain increments?

And then here is where my lack of experience with reading pressure comes into play...what am I looking for, to help me know when I have added too much powder? Split case necks? Primer falls out primer pocket when I eject the case? Worse case scenario... lug separation on bolt?, stress cracks where barrel and receiver mate ?

I always just load to what is in the books.

you look at the primer cup on the edges. if it doesnt have a defined edge youre getting hot. .2gr increments once you see it getting hotter, .5 before. on your rifle 28 or so will be getting close to your point to start watching. lt32 is one of the most popular powders out there second only to n133 in a 6ppc. you have a special circumstance here having a sako instead of the usual 6ppc in a custom action so even if you do find a load in a book it will most likely be from a BR rifle. the 6ppc is such a hotrod most folks wont put any data out there JUST because of the occasional sako shooter. like I said just put 26gr in there and go shoot a 3 shot group and look at the primers. if you have any questions post some pics of the primers or send them to me. you have to be real careful on who or where you get load data from. if your cases are already formed 26 should be your starting point. let us know how that goes. that is a light load but shooting that one first will give us some more info about where your max load will be (hint: it wont be above 29.5 or 30 like where most people shoot their PPC)

Great, thank you.

In my custom actioned BR 6PPC I was told to start at 27.3 and go up in .3s with LT-32, but also being new to the PPC, I started with 26.0 and worked up.

I agree with the others, you don’t *need* to find it in a book. I have a Sako 6PPC-USA with factory chamber so I would probably start at 25 or 26 he and work up in .3 grs increments. Like you I have no reason to push for higher velocity so If I found a good node I’d quit. There is no need to find the upper limit.

 

[Webphut]

Ok, Thank you all. I feel more comfort with the information. I will start at 26 grains and work my up from there. I too have a USA version in same rifle. I will apply this to that rifle too. Thank you all for the input.

L T 32 Start at 27.6 You can go to 30.0, that becomes a compressed load and i do not like it that hot. 29.1-29.5 is what mine likes with the same format you are shooting except the Berger bullets. 29.5 should give you 3450FPS 28.8 would be 3350FPS or there about

he is shooting a sako. that load is way too hot.

I said start at 27.6. In a PPC thats 3230 or there about

Hope your wife has a good life policy on you.

An EXCELLENT POLICY. I shoot 29.5 in My Bat 3L under 60 degrees and reduce the load 2 tenths for every 5 degree increase in temp. I holds the 3450 node with NO pressure signs. On a side note, that powder was developed by a Good friend of mine Lou Murdica. He was trying to duplicate T-32, the Original T powder from Thunderbird Cartridge Company here in Phoenix. Thats where the Name LT-32 came from."Lou's T-32. He got real close,but no CIGAR. Lou also wrote the Berger manual and tested ALL of Bergers bullets in his tunnel, to which i have an open invite to any time i want to use it.

A Sako is not a BAT action. 27.6 might be a max load for this action.

A Sako is not a BAT action. 27.6 might be a max load for this action.

27.6 is pretty lite. If he has a Bolt lift problem he can reduce the load or try RE-15, BLC-2 or V135

In my BAT 6 PPC, I have found LT-32 to be 1 full grain faster than N133. However, I found LOT #1 to be even hotter (faster) than subsequent lots. In one of my barrels, I normally shoot 29.3 gr. of N133, but equivalent velocity can be had with 28.3 gr. of LT-32 (LOT #2). For custom actions, I would start at 27.5 and work up from there. Good shooting....James

I don't listen to ANY load data given on forums and neither should any reasonable reloader. It's YOUR firearm and YOUR life. Published data or Quickload data only for me. My $.02 take it or leave it.

As we both know different lots are yielding different velocities and pressures. Lot 10 seems to be the middle ground.Not to Fast, not to slow.The guys from back east are shooting 30.2 of V-133- 15 lot pretty well. I cannot get that to work, and i have tried pretty hard, although we do not have the humidity those guys are dealing with back East. In the Cactus Wayne was shooting LT with an undisclosed amount. I suspect around 29.1-29.5

I agree 100% I trust NO ONE, except the Guys i know and trust. A lot of the powders that we use in short range benchrest are not even in quick loads or published manuals I E 18166,18167, 45710,144, WCC6196,12020,SG201, All 8208 variants, I can go on , but you get the idea

 

[Webphut]

I’m going to start at 26 and slowly work my way up. I have found low nodes with my Sako at 2980 FPS and then opens up to who knows when. This is not with all powders, and this is the FPS noted with the load data. This particular load with the Berger 64 br column bullets and LT-32 powder is definitely a time I could use a chronograph.
