Bullets for the 7.5x55 Swiss (k31)

Hi guys,

What bullets are you guys using in your K31 swiss rifles? I want the velocity of the lighter 308s but given that the rifle is sighted for 300 metres i know that light bullets will shoot very high.

This will be for service rifle competition so they need to be a decent bullet and ranges will be 100m, 200m and 300m - occassionally 500m

Thanks

I am still shooting the old 174 FMJBT used in US service rifle match ammunition and those bullets shoot just fine in a K31.

If you are serious about match shooting try the 168 match bullets first. Then the 175 SMK bullets.

Those should close to your ladder settings. I am not looking at my K31, but my recollection the lowest setting is 100 meters. Maybe 200.

The older M1911's, they don't go lower than 300 meters. (At least for my rifle, never had a carbine)

I do recommend buying a taller front sight, put it on, and file it to a good 200 yard zero with the ladder sight at 200. It is in meters but that will be close enough for "government work".

I've been shooting Widner's cheap 175 mil-spec's in mine lately. The most accurate that I've found were the 155 Palma's from Sierra. They were a bit more trouble to seat but once I figured out the OAL they were sub MOA. The 175's are pretty cheap and nearly as accurate.

How much higher was the POI on the 155s? There's an ad near me for some 155 gr matchkings that are going pretty cheap.

my reason for asking is that my current service rifle for competition is an m96 swede, but I cant shoot anything lighter then a 139gr because i have to aim off-target below the target to hit the 9 and 10 ring at 100m.

We're not allowed to modify the rifle in any way so higher sights aren't an option

With my K-31's I think the 155's were pretty close to POA with the standard sight. They are zeroed for 100 unlike my Swede which I had to put a higher front sight to get it to work at 100. With the iron sights I can't tell much of a difference between my 155's and 175's, but I'm old and my eyes are not that good anymore. My sub MOA groups have been with a scope mounted.

I'm getting ready to load my first batch....
H4350 and the 175 grain SMK's.

175 grain pills are as close as you can get to the 174 in the GP-11 ammo.

I figure I'm going to start with the bullet weight the ammo designed for it uses. Why go lighter?
