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

Triple Se7en

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.

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

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....

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!

cayugad

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

asianhunter

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

cayugad

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.

asianhunter

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

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?
