Yesterday I took the new (to me) SVT-40 out to the range to try to figure out whether to take it or the 1922 SMLE with me for this fall's walks in the woods.
For reference, in 7.62 I am firing 150gr .311 dia SPFT over 32gr of H4895.
In .303 I am firing 174gr .310 dia fmj over 29gr of H4895.
Both are within Hogdon's upper/lower limits for H4895 (via the 60% tech note).
Iron sights both.
My goal was to see which I could point more comfortably, which I could get a better aim with, and whatever else I could learn.
After tuning the gas port (1.3 works nicely, but 1.2 wasn't reliable), and the obligatory first-time-shooting-a-semi-automatic mag dump (which ended after 3 rounds because I couldn't control the muzzle rise), I started alternating the two rifles 5rds/each on a group of cardboard boxes I had brought to aim at.
Now please understand the following is my impression/opinion. I welcome other people's views.
Overall I found I had an easier time sighting the SMLE, and was more readily able to control the trigger break. That may be a factor of experience.
The semi-auto function is nice, and for something at close range makes the second shot as quick as you want it to be. I'm still looking at 4-5 seconds between aimed shots for anything at distance just to get my sight picture back and stage a smooth trigger transition.
The feel of the bolt coming back at me was unnerving. That may be a question of familiarity.
It threw casings in a randomly-forwardish direction, and not too far (5'-10'). A higher gas setting would have thrown them further I expect. Bolt damage to the brass is insignificant (just a small ding). Since I don't load anywhere near max (actually, even below starting) a bit less case volume is irrelevant.
This thing is FILTHY! The casings, which started off shiny, came out sooty and streaked and couldn't be readily distinguished from the carpet of old laquered steel 7.62x39 casings covering the place. I hunted around extensively, but only found 3/4 of the casings. The bolt and magazine same; black soot everywhere. This is understandable given that the bolt is unlocked while the barrel is still under pressure, but it takes the required cleaning into a whole new league.
When I asked, the young lady at the table next to me did not find the noise particularly unpleasant.
Recoil was not bothersome in either rifle although the SMLE was smoother (It's original config, so it has plenty of mass to broaden the impulse). I loaded them light, and neither is a 5lb rifle. With a 00 ball over a few grains of shotgun powder (my favorite), recoil was non-existent.
Accuracy, when all was said and done was good. I think I actually grouped better with the SVT-40, but both were serviceable, and neither one was much worse than my own laser-pointer-on-a-stick basic ability to point things.
Note to users: Do not pick up the 7.62 brass until it has time to cool. The chamber dwell time is much longer on the bolt action, and the brass cools to the barrel by the time you get it out. No so for the semi. -tssss- YOW!
I don't like the safety on the SVT-40. For the SMLE the safety locks the bolt, locks the firing pin, and locks the trigger. Since it is a ####-on-close you can also just chamber a round with the trigger held down, and not charge the firing pin spring until you want to (clik-click). Or, for the ultimate in safety, you can just chamber a round quietly when the time comes. Not so for the SVT; the safety only physically blocks trigger motion, and chambering anything without a low-budget-action-movie "CLA-SHLINK" sound is difficult.
So, the end result.
I like the SVT-40's looks, and it is mechanically neat to play with, but for what I'm going to be doing I just don't see it has any advantage over the SMLE I am already familiar with.
If I was in a situation where the follow-on shot could matter, I'd got with the semi-auto (and the SVT-40 is nice for a semi-auto).
But if I'm going our for deer with friends, I'll go with the old(er) beast.
I invite y'alls to share your own experiences in these regards.
