How much can you safely compress a load?
I loaded some .308 cases with 56 grains of IMR 4350 and seated 168 grain Sierra HPBTs. This is a compressed load but even with compression the rounds are too long for my R-700 short action.
They are about three-eights longer than factory ammo.
Would it be safe to push them in more to make them fit or should I pull them and start over with new components?

4350 isn't really a 308 powder, and that charge weight seems high. Are you sure you didn't get into some 30-06 data?
Pull them, start over.

STOP!
You got your load data mixed up. That's a 30-06 powder charge for a 168 gr bullet. Nosler lists 50 gr of IMR 4350 as max @ 104% and Speer shows 49 grs as max.

Yours is a big load for the 308 Winchester with a boat tail bullet. I don�t know how long your bullet is or how deep you are seating. How long is this bullet? When you seat a bullet .300� deep in a 308 Winchester case you have enough room for 43.8 grains of IMR 4350 - uncompressed. With flat base bullets 50.5 grains is compressed load in my cases. Many new bullets have a long overall length and these are hard to load for your short magazine box.

That data is for a 30-06 , not a .308 . You couldn't compress that charge into a .308 case . I've always stayed away from compressed charges myself . It's just an unnessary headache . Charges that fill the case about 85% work well for me . It's just a matter of choosing the right powder .

I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

Can anyone give me a hunting load (not compressed) for the 168 grain Sierra HPBT?

I think I'd start out with another bullet.
Aim for the exit hole.

A 168 in a 308 is very tractable. RL15, Varget, H4895, IMR4895, IMR4064, TAC, W748, BL-C(2) and the like work well.

Pray tell, where did you get that load data? I am assuming you haven't shot it yet?
I think, therefore I am, conservative.

I made a mistake. Have not fired it and won't. Almost all the pills are pulled.

I've always had good performance from W-748 and 165-168 Gr. Bullets . Loads usually max out around 45 GR. . I took quite a few Deer with the old Speer 165 RN ( discontinued ) and that charge .

Only an idiot would give you load data you cant even tell 308win from 30-06 load data. Better give up before yoy kill someone.

purple... I think you will find that people here tend toward a higher level of sense and intelligence that what you're demonstrating. The OP understands the problem it appears and seems willing to learn and go forward. Insulting as a method of educating is both poor form and rather juvenile.
