Hi everyone.

I just started shooting F class and love it. I shoot a Savage FT/R in 308. I have a question about the different types of projectiles for the .308 platform. I started with the 155 gr Berger and did ok but am wondering about the performance of the heavier bullets that are offered in this caliber.

Would it be worth using the bullet with the best ballistic coefficient and working up a new load for this new season. I see there are bullets ranging from 167 grs to 210 grains from various manufacturers.

Does anyone think there is an advantage to taking a couple of bullets with the best ballistic coefficients and working up a new load of the new season?

Thanks in advance for all your collective knowledge on the subject..

Every bullet from 155 to 210gr is presently being used. Each has their fans.

So see which your rifle, shoulder and wallet enjoy the best and have at it.

If you want to try an assortment, let me know...

Hey there!

What were you using at Winnipeg?

You are guided to a certain extent what your gun prefers. The 155 class of bullets work well, but gve some thought to the 185 grain LRBT from Berger - fantastic bullet with a VERY good BC for 30 cal.

Unlike TR where you are limited to 156 grains, the best FTR shooters balance velocity, accuracy and Ballistic coefficients. Listen very closely to advice from Terry Perkins, Scout and MPWolf..... These guys know their stuff.
 
155 grain Bergers

I was using 155 gr Bergers at the PGW shoot. I was just wondering if a heavier bullet would work better.. I shoot a Savage 12 F/TR with a 1/12 barrel so i guess i am limited by that.. I have been looking at the BC of the heavier projectiles and wondering if i could gain anything by using one of these.

Sorry about the not doing a search on this but i find the search function on this board very broad and difficult to use effectively.

You are NOT limited to anything with your gun. It is very accurate (I know from shooting with you), and a 12" twist will stabilize anything you can shoot from a 308, all the way up to 210 grain bullets if you wanted. Brian Litz even makes a foot note in his new ballistic charts that the Berger 190's will stabilize in a 13" twist with enough velocity
 
Thats good to know... Was thinking of trying a heavier bullet such as the 180 gr VLD but i may even try the 190s now... Thanks for the info... I am looking forward to shooting the Western Canadian PGW shoot this year.. Hope to see you there..

the search function works and works well with practice all the mysteries of life can be revealed in the CGN search function:)
 
Just discovered the advanced search function

Ok Thanks JBD.. after seeing your post i scrutinized the search function and found the advanced search... sorry for being so dimm...

The "top 3" 155-class bullets today are the Lapua 155 and the Berger 155.5 (essentially tied) and the Sierra 155 (#2156) (quite a close third place). It will be very difficult to improve on a Berger 155.5, in terms of performance in the wind, accuracy, and ease of achieving accuracy. It can be done, there are a _few_ heavier bullets that will do it, but most run of the mill heavier .308 target bullets don't actually outperform these three "super 155s" (e.g. the Lapua 185 does not, the Sierra 175 and 190 do not, etc)

The Berger 185BT (note "BT" not "VLD") will outperform these 155s and I think I understand that it is a straightforward bullet to get to shoot accurately. Some of Canada's top F/TR shooters are using this bullet, ask them for their experience and recommendations
 
if you want to try something heavier than the 155 class bullets, the 185 BT is the one to try first. Very easy to make shoot well, the usual .308 powders work, and most chambers/throats can digest them quite nicely. Remeber that heavier doesn't always equate to better ballistics.

what about 155GR Amax ???
is good for 1000Y??

It is good for 1000y shooting, though it is not one of the current state of the art 155s. (Meaning, if you are out to win a world championship match it might not be on your shortlist of bullets to use; but that's about the worse that can be said about them)
