Lightest bullet that can be shot out of 243 win w/ 1-8" 26".

[Fast1]

Picked up a Used model 12 from a guy here in town yesterday. He put a 1-8" 26" McGowen barrel on it. He only shoot's 105g Bergers
out of it. Got 300+ 105gr. bullets with it and 500 pcs. of brass. So my question is , What is the lightest bullet I can shot out of this
barrel. I also have another savage in 243 win. but, it has a 1-9 22" factory barrel on it and I use 70gr. Nos. B/T and 68gr Bergers in it.

Thanks for any input.

I have shot 68 gr bullets out of a 1 in 8 twist 6br, each barrrel has its own personality, the best way to see what your barrel likes is to give it a try.

I is confused... If your asking "can it shoot" 82 is correct, try and find-out.
If you are asking about the twist... That is a bullet maker question, but here is what I can say:
Hornady V-max has a PRM limit upwards of 430,000 RPM
Sierra Blitz has a very similar RPM limit.

+1 on seeing if the gun likes them. Ya never know until you try. Get some 55 b-tips or 58 v-maxes. A fast twist doesn't effect the lighter bullets like a slow twist will effect the heavier ones.It is not possible to over stabilize a bullet.It is possible to have them blow up due to high rpm's.I use to use the Hornady sxsp(now discontinued),60 gr I think,out of my model 7.Velocity max on them is 3200 fps per Hornady.They worked fine in the short barrel but when I tried them in my 24" SPS most of them won't make it to the target. I won't even bother using them in the 26" LRP.Good luck with the 243.I have 3 and love the cartridge.I've killed a pile of groundhogs and deer with mine.

I shoot both 58 and 65 Vmax's and 60 Sierra's from a full case of Varget, that's 44gr from a 26 inch 9 twist Mcgowen all well over 4000 fps, and none vaperize before there intended target.

Thanks Dean

58 and 65 Vmax's and 60 Sierra's from a full case of Varget

I have had the same experience.

if one googles 'bullet weight and barrel twist' several of the barrel makers will enlighten one....
