RELOADING FOR SAKO TRG22

[corpsman1]

Hey guys, I'm new to reloading and would like to know if I should set my bullet to jump to the lans or does it help with the trg22? Starting to shoot F class with SMK 175gr. and IMR 4895 and Lapua brass. Any advice well be apreciated.

You are going to have to find out what the load your working with likes. Some work well jumped others seated in the lands.

I start all my load development with the bullet just touching the lands. Then I work up my powder charge until I find what charge of powder works best/most accurate. I then start seating the bullet down (away from the lands) in .010 steps until I find the sweet spot.

I am by no means a expert on reloading but that is what works for me.

Take care,Stan

Hi I am using the 30 cal Dyer HBC-BJD 155grain Palma projectiles, Lapua brass. I tried the felt pen seating depth set up in my Sako TRG 22 1:11 twist to just missing the lands, resulting grouping all touching almost one hole at 100 yards. Got me a Hornady seating depth gauge set up I have 0,063" jump !!! I thought I was just missing. Tried closer as per all the advice still shoots best with the big jump !!!. My powder is 47.5 grains ADI AR2208 I think this is Varget you best check this out , Federal 210 primers. Velocity 26" barrel high 2898 fps low 2861 fps average 2885 fps, ES 37, ED 10. No pressure signs or bolt lift or brass issues. 300 yards 60 x60 500 yards 60x 60 900 yards 59x60 first try seams to work for me. Standard Sako TRG 22, Schmidt and Bender PMII 5-25x56, Sinclair F/Class bipod with their rail adaptor and rear bag.
Be careful work loads up safely per the manuals this works ok for me in New Zealand maybe not you. Have fun zero at 100 yards 300 4.00 moa 500 8.50 moa 600 13.5 moa 800 20.5 moa 900 25 moa 1000 30 moa. These are actual range tested data.

To this date all of my 308 rifles like some jump with the 175 SMK. None shoot well seated into the lands. The amount of jump varies with each rifle. Most are more than .020. Powders vary.

That's my experience too with this bullet. 20 thou' off the lands is a good starting point. You'll likely find it will perform well with this amount of jump. You don't say though if you plan to use it as a magazine rifle alongside your F-Class shooting. If so, it may be that the maximum COAL that the magazine allows is what you'll have to seat the bullets to, just checking that you're not jamming the bullet into the lands at that length (unlikely, the way most factory rifles are throated, but still essential to check).

No chrono data this trip. Wanted to see if it was worth the effort. I know it's not the powder you asked about but I thought the results were pretty good. These worked in my rifle, they may not be safe in yours.
