loads for Savage #12 LRP

Hi Everyone; flexible here and I'm about to start loading rifle ammo for the first time. I have decades of experience with handgun ammo but no rifle. I have purchased a Redding T7 press, type 'S' competition dies with a .290 bushing for the neck die. I also ordered a Sinclair mandrel expander. I have the usual other stuff; micrometers, RCBS Chargemaster, etc.
My rifle is a Savage #12 LRP, The brass is once fired Hornandy and virgin Lapua (small primer) I also have 130 Berger bullets & 140 gr Lapua bullets.
Does anyone have recommendations or favorite loads for a Savage #12?
thanks
flexible

Welcome flex.   NIce new stick to start loading for..
Hard to beat 41.9 gn H4350 under a 140 gn pill, in my SAV 10 (24" w/break), Hdy brass.
Also need to adjust for case capacity since HDY is more than Lapua, in order to get same fps from both cases.
Usual caution applies,, to work up the loads from a safe starting point..
... rule #9 ...

Welcome to our forum flexible!😊

You picked a good rifle to jump into the Creedmoor arena. You also have some great equipment and supplies for your reloading. Lot of similarities between handgun cartridge and rifle cartridge reloading. - and some differences. The basics are the same - when looking for the best load for your particular rifle, always start low and work up. No two rifles even from the same manufacturer are the same. Select one bullet and powder to work focus on initially and NEVER mix case types.
For the 140 gr Bullets and 26” barrel, it’s easier to predict for you that you will find an accuracy node somewhere in the low 2700 fps range and again in the low to midrange 2800s. Exactly what powder charge is not predictable.
When you can research our reloading section in the forum and do some reading on the net on the following load development techniques: Optimum Charge Weight, Ladder rest, Satterlee velocity test. The degree of your passion to shoot with great precision will determine how much of this material you will learn and employ.
Always a good idea to look at some reloading tables. Start your development with low to midrange charge recommendations and work up in charge weight looking for accuracy and indications in your brass that you are starting to push your charge weight too high for your brass and rifle. Just because there may be an accuracy node for your rifle in the low 2800s doesn’t mean that that is where you are going to get the best long term accuracy and barrel life.
Like I said, you are starting out with some great equipment. Do you have a reliable chronograph. If not, it’s something you should consider. Most serious reloaders feel a Magnetspeed (one example) will pay for itself just in the data it provides to minimize time and component waste during load development.
Good luck- we are here to help. This group of guys gets a kick out of helping other shooters maximize their rifle precision shooting.

Thanks everyone for all the great advice. Benn doing some more homework and I also have a Little Crow WFT for trimming and a hand deburring tool
BUT what about case annealing? I do not want to use a torch but the induction models I've seen are very pricey.
How often should i anneal the brass? Has anyone seen reasonably priced induction models?
thanks

Flexible; I also have a 12 LRP, ( love it). I started with a load workup and my gun liked 41.9 gn. of H4350, 139 gn. Lapua scenar, Starline brass and CCI bench rest Primers. I hope this at least gives you a starting point.

Do a search for hot salt bath annealing. Costs less than a hondo to get started and the temp is very controllable.

Thanks DMC000; this makes me feel more confident. I have H4350 coming in this week along with CCI BR primers - I already have 130 gr. Berger bullets & Lapua 130 scenar, plus Lapua brass. I started setting up the dies today and will finish this week when I have more time.
thanks again
