Stevens 200 .223 1-9 twist?

Am I going to get 40 grain V-maxes to stablize with my 1-9 twist barrel? Don

I have a Stevens 200 .223. I don't have a clue what the twist is but I would guess 1-9. What ever rate it has, it shoots 40 grain Sierra HPs in .6-.7" groups at 100 yards. Since it does so good with these I haven't tried the V-maxes but I would expect about the same results.

Thats great to hear. Some have said the 1-9 won't shoot bullets under 50 grains. Don

Rule of thumb is heavier bullets go better with faster twists. Note that it is a general rule of thumb and does not apply w/o  fail to all rifles. Best thing to do is load a batch of ammo and try 'em out.

Thats what I'm going to do. If they won't stablize, at least I can sling some lead ;D. Thanks, Don

They'll stabilize just fine.  I'd be more concerned that if they are a lightly constructed bullet and you get them going too fast that they might "blow up" in mid air due to centrifugal force.  If you're shooting and not hitting the paper I'd look into that possibility.

With modern bullets the only issue with spinning the crap out of them is that any manufacturing flaw (non-uniformity in jacket thickness causing the center of gravity not to be in line with the geometric center of the bullet for example) will cause the bullet to wobble a bit or fly with the nose of the bullet not in line with the line of travel (stable but cocked up and to one side like a punt in football that has a good spiral on it) and hurt accuracy.  Your groups might open up a small bit with inexpensive lighter bullets.  With the better bullets, you won't notice it.  Short of spinning lighter constructed bullets (made for the .22 Hornet) apart, you can't really "overstablize" a bullet and that 1:9 twist will comfortably stabilize the heavier pills.

helotaxi - Has it right. Generally do not get a faster twist than the bullet you are going shoot needs. You do not see the benchrest crowd shooting fast twist barrels.

not too sure how much the spin rate will affect accuracy in your rifle but i have tried the hornady spsx in my rifle. the those frangible bullets didn't explode from spinning for me

Thanks guys, I have some 40 grain Hornady V-max-60 grain Hornady V-max and Midway 55 grain loaded with 3 different powders. Now all I need is this snow to melt so I can get to the range ;D. It's on a gravel road about 4 miles in a wildlife management area. Don

40 V-max's worked in my NEF 223 1:9. H380 powder, about 3100 fps. more accurate than the heavier slower bullets.

Will a 1 in 9 inch twist stabilize match bullets up to 77 grains?

I do not think so, but you need to try some to be sure. I would think a 1 - 9" twist would be very close to stabilizing it, but just not quite there. Remember, it is not the weight of the bullet, but the length that influences what twist rate it takes to stabilize it. Match bullets of that weight usually have a boat tail and a long pointy nose, these add up to a long bullet. You could look up the bullet manufacturers site and see what they recommend for a twist rate. Some of them list their recommended twist rate - some do not. I have built up a 22BR with a 1 - 8" twist for 75 - 80 grain bullets.

I have a 1/7" that will keep the 40 gr. vmax in 3/4" or so and will do a little better with the Hornady 69 gr. but for what I use the .223 for the 40 is perfect.  I have 223s in 7, 9, 12, and 14", the 12s may be slightly more accurate with the 40s but not much.

Most 1:9 will stabilize the Hornady 75gn HP (barely) but few will stabilize the A-max, at least not inside 100yds.

I have a Stevens 200 in .223 that shoots them both very well, and know of three others, personally that use the 75 A-Max for long range varmints, in 1-9 Savage rifles. There are many others posting load data and shooting them that love them. I will look on the 75BTHP box and see what the required twist is, but I am fairly sure they have 1-9 on the box. I know a guy with a Remington that can't shoot the 75 A-Max in his because they keyhole, but he shoots the 75's fine. I am out of the 75 A-Max, so I can not tell you what the twist says on the box. I run them around 2750, seated .020 off the lands, single load with VV540 and Remington 7 1/2 primers in WW brass.

The recommended twist rate for Hornady #22792 (75 GR BT A-Max) is 1 - 8". You will have to try them to be sure, but do not be surprised if they do not stabilize with a 1 - 9" twist barrel.

I agree some guns won't shoot the a-max with a 1-9 twish. Look them up at midway usa and look at the reviews.
