On 6 May I sent Ruger a letter asking about the extra long throat on my 1979 Ruger #1A in 7x57. I enclosed a stamped addressed envelope. For a reloaded 154 grain cartrige to reach the lands the distance is 3.377". Maximum OAL is listed in my Nosler Reloading Manuel as 3.065" In my letter I asked Ruger if my rifle was made that way and if so why.
As of today, no reply. Can any Forum members explain to me why my rifle has such a long throat?

I have an older Ruger #1AB in 7mmx57 that has the same issue, so will be interested to hear thier response. With the long throat my rifle seems to handle heavy bullets best but I have taken a large number of deer with 139gr and 140gr. It shots well but has never been a tac driver. I've thought about having the barrel set back and adding an accuracy block to the forend but have not gone that far yet.

I have a 1V .243 with a long throat. I don't worry about what the manuals say about OAL, it's a single shot. As long as the bullet isn't falling out of the case I see no problems.

Thank you for your responses. I hope to get more.

The older #1's in 7X57 were designed around the original military loading which takes a 175gr round nose projectile. My RSI is one of those. With 175gr loads or heavier she'll cut one ragged hole at 100yds. Drop down to 140gr loads, and she opens up to a little over an inch at 100.

I took Ohiosam's idea and reloaded some Hornady 154 gr SST's with an OAL of 3.353. The bullets seem secure in the case. They should be about .02 from the lands. Next week I will go to the range and see what I have. With luck my groups should tighten up.

If this option doesn't improve my groups, I will go to a 175 bullet.

I look forward to hearing about your results. See if I'm a hero or a zero.

Have had #1s for years, they typically had long throats. This has never been a negative issue and as some have said, as long as the bullet doesn't fall out of the case, go ahead and seat them out.

My current #1S in 45/70 is the first #1 I have ever had with a short throat, and it is better said to have zero throat.

Keep em coming!

Reloading for my 1979 Ruger #1A in 7x57 with 154 gr. Hornady SST's with an OAL of 3.353 seems to have solved my accuracy problem.

Good to hear you are getting there!

Pretty well proves that some guns just are picky with what they like and don't like.

Years back, was loading for a 270 and it just didn't seem to like anything I fed it.

A friend suggesed a powder, which to my way of thinking was much too fast. He said try it , which I did and it worked.

AS I've said earlier, I have never found the #1 throught to be a negative factor in groups, but every rifle can/could be picky on the components which ring it's bell.

Seems you have found the sweet spot, but if you need to go deeper, the 160gr Nosler Partition is a good one!

Keep us posted.
