I am about to load up some test rounds with the 155 scenar and was wondering if anyone could tell what the overall length of the cor-bon match 155 scenar ammo is? Thanks.

Re: Lapua 155 Scenar
I can't answer your question about corbon but I can tell you my scenars like to be jumped .010 to .015 in both my GAP and AI. I hope that info is useful.
Good luck... this is an amazing projo.

Thanks for the info, what is the overall length on your cartridges?

I'm not sure because I only measure with a comparator. With the comparator it's 2.245, but I think the OAL is somewhere around 2.86?

Re: Lapua 155 Scenar
I was thinking about just loading mine at 2.8, right now I am just trying them in a 5R Milspec, but have a GAP on the way. I am assuming the factory ammo loaded with these would be around 2.8, do your rifles not shoot with them seated that deep?

I'm not sure - I never tried.
If I could recommend two tools to you they'd be these:
this: http://www.midwayusa.com/viewproduct/?productnumber=570611 with http://www.midwayusa.com/viewproduct/?productnumber=459683
AND

Measuring OAL won't be nearly as consistent as measuring to the ogive. You should also know how long your chamber is so you know what you're jumping or jamming and can monitor your chamber/load as your throat erodes.

Re: Lapua 155 Scenar
I will definitely look into that if I do not get satisfactory results with a standard seating depth.

Re: Lapua 155 Scenar
I've found loading the 155 Lapua scenar at 2.214 ogive and about 2.835 oal in my Aw ,trg,and m40a1 seem to work really good.

Re: Lapua 155 Scenar
I find the scenars shoot best with little jump... I load mine to about 0.01 away from the lands

Re: Lapua 155 Scenar
I have loaded quite a few 155's for my 5R at 2.890 OAL and my Gap likes them at 2.855. I jump them. at least .010 in the Gap and about .050 in the 5R. They do well.

Re: Lapua 155 Scenar
Well I loaded up some test loads with varget and seated them at about 2.84 oal and 2 of the five loads printed sub 1/2 MOA 5 shot groups.
