which bullet is better for 1 in 28 twist barrel the heavy bullets or the lighter bullets 250 or 300 grains. thank u!!!

RE: 1 in 28 twist
 

In general because all rifles are different, the optimum sabot/bullet size for 1-28"s appears to be 300 grains for barrel sizes 22" to 28" -- yardageranges between 50 & 100 yards. A majority of 28s will shoot any sabot well with the right powder/primer/dry barrelload from 180-400 grains real well - if the rifle is solidly constructed.

Conicals are different thou. I'm assuming you are shooting sabots - so I'll end the discussion here.

RE: 1 in 28 twist
 

for a sabot bullet 300 grains and up is good, for a conical type bullet 400 grains is a very god weight.

RE: 1 in 28 twist
 

Only your rifle barrel knows that answer. It depends on the rifle make, the barrel length, and the design of the projectile also. Some of my inlines like large heavy bullets and sabot combinations, while others seem more then happy with a 240 grain class. I found the 250 and 300 grain are the best shooters for the most part in any of the inline rifles. Yet some of them will shoot about anything you stuff down them. My Black Diamond XR for instance will shoot a 200 grain Shockwave with excellent results. It will also shoot a 405 grain Remington FP with great accuracy as well. Only your rifle will answer that. What kind if rifle are you shooting? Perhaps the forum could offer some suggestions that worked well for them with a similar rifle. Not that it means yours will also shoot the same load well....

RE: 1 in 28 twist
 

and also was wondering if its ok to use a 3fff powderwith 300grains bullets and, if ok how much powder charge is safe to use? thank u guys!

RE: 1 in 28 twist
 

Yes you can use 3f powder for large sabots and even large conicals. At least I do it all the time with real good results. You need to rework you load a little as the 3f will produce higher pressures because of the rate of burn. I usually cut the 2f load that worked by 15% and try from there.

For instance.. if I was shooting 100 grains of Pyrodex RS and a 300 grain XTP and getting excellent results, but wanted to try Pyrodex P. I would start at 85 grains and then work the load from there to see where it comes in at.

Triple Se7en 2f and 3f is an area I am not familiar with. I only get the 2f in my area. Triple Se7en the poster would have more information for you on that.

Goex 3f I shoot all the time and like it a lot. It burns cleaner then Goex 2f and I like the way it shoots...

Good luck

RE: 1 in 28 twist
 

thanks cayugad! i am going to try 3f american pioneer w/ 300grains xtp

RE: 1 in 28 twist
 

if your going to shoot American Pioneer Powder then you definately want the 3f grade. The 2f grade looks like fish tank gravel it is so course. Good choice. Very little fowling there. I have a couple pounds of Pinnacle 3f I just bought to try some more shooting with.. Good luck with your powder.

RE: 1 in 28 twist
 

cayugad! is it safe to use 150 grains by volume 3f american pioneer w/ 300grains xtp? thank u!!

RE: 1 in 28 twist
 

You will need to check your owners manual to find out what the manufacturer says is the max load your gun can shoot. For example- if the max loose powder load is 120 grains of 2f powder you can shoot 3f but reduce it by 15%. Again it depends on the gun. What gun do you have?

RE: 1 in 28 twist
 

150 is the max less 15% that would be 135 grains.thank u!

RE: 1 in 28 twist
 

You never did say what gun you have. Max load is sometimes different for pellets and loose powder. Knights for example (don't know about their revolutions and the older guns are only rated to 120 loose) are rated for 120g loose powder and 150 in pellets. The owners manual should tell you for sure.

RE: 1 in 28 twist
 

Depending on what rifle you have.. that would answer that question. Some of the rifles allow 120 grains of loose as a max load in 2f. Some such as the BPI barrels and older inlines I think had a 100 grain max load limit.Again in 2f grade. When youincrease to the 3f grade you increase the barrel pressures. The usual number thrown around is 15% decrease in charge strength when changing from the 2f to 3f.

Also the length of your barrel will make a big difference. If your shooting a 22" barrel there is no need to shoot over 120 grains of anything because you are wasteing it. If the barrel I believe is 28" it will manage to burn off 150 grains of powder.

So to answer you question I will say NO! it is not save to shoot 150 grains of loose American Pioneer Powder especially the FFFg grade. I would keep the loose powder 3f charge around 100-120 MAX. In 2f and pellet form the go ahead and shoot 150 grains. If your rifle allows such loads.

Do not be surprised if your accuracy flys out the window as fast as your money, shooting those large charges of powder. Especially when shooting pellets.

What kind of rifle are you shooting? I do not remember reading it in the posts... Good luck with your rifle.

RE: 1 in 28 twist
 

348 Grain if you use Powerbelts..............

cayugad! i have thomson center omega 28" stainles steel barrel.thank u!

RE: 1 in 28 twist
 

Asianhunter... you have an excellent rifle. One of the very best on the market. It is Stainless Steel. Your rifle will shoot 150 grains of powder anyway you want to put it in. If your shooting 3f powder I would limit the loose powder charges to 120 grains of loose powder just because of the increase in barrel pressures that 2f-3f conversions produce. Whether they actually do produce these differences I could not say. I never put them over a chronograph. But better to play it on the side of safe.

Some excellent long range projectiles for your rifle would be 120 grains of loose powder and a 250 grain Shockwave. With that load you should have all the power you need to make a 200 yard kill. If you want, you could also shoot 3 50 grain pellets with the same projectile and have similar results. Both will get the job done.

Good luck with that rifle. You sure got a good one there...

RE: 1 in 28 twist
 

No I would not consider 150 grains of FFFG (3FG) a safe load in most all "Magnum" MLs. There are a few custom ML's that are supposedly rated for higher loads.

Ensure you verify for your particular rifle first.
Safe estimates for the 150gr "Magnum" 50 cal ML's:
Up to 150grains FFG Max
Up to 120-125 grains FFFG Max (Accounts for about a 15% powder reduction).

With 3FG, you will find that around 120 grains powder is about all you can stand for sighting in. That's of course if that much powder will even be accurate. The best way to tell is by starting out moderate at say 70-80 grains 3FG and see how things print. Then bump up if you wish.

Also, the 300gr XTP comes in two flavors, the standard 44 cal (.430"and the XTP MAG which is tighter fitting (.452" Black Sabot). You will find that the standard 44 cal XTP (Green Sabot) will eventually skip the rifling if you push them too fast.

RE: 1 in 28 twist
 

You may wish to check your math.

15% of 150 is 22.5.

Subtract 22.5 from 150 equals 127.5.

Round down to 125gr 3FG.

yeh mysubtraction is wrong!

RE: 1 in 28 twist
 

asianhunter: I know you are new to this sport as you said so in another site post. I have the same rifle stainless Omega synthetic stock. I think you will find that you do not need to load anything near those maximum loads to get the job done. Unless you are planning on shots exceeding 150 yards anything over 100gr. of any of the powders is just overkill. I hunt elk and consistently shoot completely through the chest (as long as bone is missed) with 90 gr. of Black Mag'3 and 300gr. SST bullets. I did the same with 90gr. Pyrodex and a 295gr. Powerbelt aerotip. These shots were at less than 100 yards and the elk were fair sized cows. Still way bigger and tougher than any deer. I have had very good luck with Black Mag'3 although it is difficult to find in many areas. Most Omega owners seem to love the way it works in the Omega. Tripple Seven does not work very well in my Omega as it forms a real bad crud ring which makes second loads very difficult or impossible. I would start with Pyrodex either loose or pellets as a lot of the initial development of the Omega was done with Pyrodex from what I have been able to find out. It is also easier to find than most of the rest. It is pretty dirty but as long as you follow the normal shoot, spit patch , dry patch, reload and shoot it works just fine.

RE: 1 in 28 twist
 

MLKeith thanks for the advice, i will not overcharge!thanks again!

RE: 1 in 28 twist
 

By the way if you are going to shoot those heavy loads with the synthetic stock Omega you will likely want to get a simms limbsaver recoil pad. I put one on my Omega and the result is great. Best recoil pad I have ever experienced. They make one specifically for the Omega and Encore.

RE: 1 in 28 twist
 

I'll second that, the simms limbsaver recoil pad is excellent!
